Progress 07/01/11 to 06/30/16
Outputs
Target Audience:Target audiences include wheat producers, extension personnel and colleagues involves in wheat research at KSU and other institutions Changes/Problems:The research and education component has provided for changes in producer behavior by supporting adoption of improved wheat varieties. Research discoveries related to FHB resistance in Everest have resulted in new breeding approaches for improving FHB tolerance. The work on genomic selection has resulted in changes of breeding methodology to increase the efficiency of the breeding program. Examples include prediction of subsets of materials to reduce the amount of plots harvested, resulting in breeding efficiency. Research on genomic selection for quality has provided a framework for increasing efficient selection for bread baking quality that will increase the efficiency of the breeding program and provide varieties with superior quality traits to the wheat industry. What opportunities for training and professional development has the project provided?The primary effort was graduate student training. Six graduate students were a part of the program at some point over the last five years. Numerous (>20) undergraduate students were exposed to a research environment during this time. How have the results been disseminated to communities of interest?Research results were disseminated to the research community through publication and presentations at professional meetings. Communication to producer groups came in the form of direct presentations (>50) at field days and wheat schools. An average fo three radio interviews per year were also targeted to producer groups. The PI also provide input and data to support extension publications. What do you plan to do during the next reporting period to accomplish the goals?

Impacts
What was accomplished under these goals?
Four new varieties (1863, KanMark, Larry and Zenda) were released during the course of this project. FHB resistance from Everest was mapped in two separate populations. One (Art x Everest) was phenotyped in the greenhouse and the other (Everest x WB-Cedar) was phenotyped in the field. Publications for both studies are in preparation and markers are being converted into forms that are amenable to marker assisted breeding. Phenotyping of the Art x Everest population for response to barley yellow dwarf is continuing. Heat tolerance lines derived from Jefimija have been re-incorporated into the breeding program. Much of the screening effort transitioned to evaluating novel sources. A set to Triticum dicoccoides accession with heat tolerance is under continuing evaluation and have been used for germplasm development. Genomic selection has been implemented in the breeding program resulting and results have been published. Additional work included identification of Aegilops geniculata accessiosn with tolerance to drought, development of a greenhouse based drought screening protocol using soil moisture sensors in a strucutre that allows access to root tissue. Seven T. dicoccoides accessions with tolerance/resistance to wheat streak mosaic equivalent to, or better than, Wsm2 were identified. More than 50 presentations were made to mad eto whea tproducer groups throughout the project. Ph.D. students trained found employment in academia and industry.

Progress 10/01/14 to 09/30/15
Outputs
Target Audience:The target audiences would include primarily include wheat producers through field day presentations and other communication activities and also other researchers through publication and other scientific communication. Changes/Problems:There are no major changes. The biggest modifications are in approaches to implementation of genomic selection in the breeding program as a result of knowledge gained. We will divide preliminary lines by pedigree, testing approximately one half of the lines in an environment and use models to predict the other half. This will make the program more efficient. We anticipate this change for the Fall of 2016. What opportunities for training and professional development has the project provided?The project is the home to five graduate students, including a Monsanto Beachell-Borlaug scholar. The students attended professional conferences including the Annual Meetings of the US Wheat and Barley Scab Initiative and the Plant and Animal Genome meetings. How have the results been disseminated to communities of interest?Results have been disseminated through publication, presentation of posters and abstracts at professional meetings and through producer field days. Presentations were made at seven producer events in 2015, with a total audience in excess of 400 people. Training was also provided to Extension agents to facilitate broader dissemination. What do you plan to do during the next reporting period to accomplish the goals?The primary focus is development of new varieties, which in an ongoing effort. Theis effort will be maintained. Implementation of GS will move to greater integration in the breeding program through implementing selection schemes that reduce field plot numbers without compromising data collection and initiation of rapid breeding methods implementing GS and doubled haploids. Evaluation of Aegilops geniculata accessions for tolerance to drought will be completed and an evaluation of a set of Triticum turgidum ssp. dicoccoides accessions for tolerance to high temperature stress will be initiated. Mapping of FHB resistance from Everest should largely be completed and characterization of potential new sources of resistance to wheat streak mosaic virus will be pursued. An initial screening of Aegilops geniculata accessions for resistance to barley yellow dwarf mosaic will also be carried out.
Impacts
What was accomplished under these goals?
Two experimental lines of wheat were proposed for increase for potential release in 2016. KS060106M-11 (tentatively named 'Zenda') is derived from Everest and combines the FHB resistance of Everest with better quality and resistance to stripe rust. KS060143K-2 (tentatively names 'Larry') is adapted across a broad swath of Great Plains and has excellent resistance to stripe rust, is intermediate in its response to FHB and has good drought tolerance. Genomic selection has been implemented in the program with good results. GS has performed as well, or better, than conventional phenotypic selection for yield. Excellent results were obtained in predicting quality phenotypes in the CIMMYT wheat program, which is a positive development toward implementation in the Kansas program. Heat tolerant lines derived from 'Jefimija' were cycled back in to the breeding program. Progress was made toward mapping of FHB resistance in Everest with completion of two greenhouse screening tests of an Everest x Art population and field screening of an Everest x Cedar population. Preliminary QTL maps hav ebeen made. Germplasm development efforts were focused on the use of Aegilops tauschii, Aegilops geniculata and Triticum turgidum ssp. dicoccoides. Amphiploids were created between wheat and 22 accessions of Aegilops tauschii and 2 accessions of Aegilops geniculata. The wheat-Ae. tauschii amphiploids were crossed with T. dicoccoides. Seed was obtained from crosses with 27 T. dicoccoides accessions. The primary goal of this work is the development of improved tolerance to abiotic stress, though disease resistances will almost certainly be transferred.

What opportunities for training and professional development has the project provided? The project currently houses six graduate students. Four of the students are working toward Ph.D.s while two are working toward M.S. degrees. One student is a Monsanto Beachell-Borlaug International Scholar and has attended the World Food Prize event, as well as two professional conferences. Two other students attended professional conferences. Two Assistant Scientists on the project attended the American Seed Trade Association meetings. How have the results been disseminated to communities of interest? Results have been disseminated through publication, presentation of posters and abstracts at professional meetings and through producer field days. Presentations were made at six producer events in 2013, with a total audience in excess of 300 people. What do you plan to do during the next reporting period to accomplish the goals? We have made consistent progress toward the stated goals. We will continue to pursue the ongoing projects. The breeding program will follow the protocols that have served us well over time and supporting research will be carried out primarily through graduate student research. Funding for the project is strong and includes public, private and wheat producer support. Primary objectives for 2014 include assessment of lines derived from heat tolerant parents and, if appropriate, use of those lines for breeding and as recurrent parents for the transgenic starch synthase. We will also collaborate with Jesse Poland to map phenotype a population derived from Jefimija for heat tolerance. A prelimary QTL map of FHB tolerance from Everest and Art will be generated. Materials carrying Lr34 and Lr67 will be evaluated under field conditions. A project to map BYDV resistance from Everest will be initiated using the existing Art/Everest population. Genomic selection projects will be continued and refined. We anticipate the release of at least one variety in 2014 and will likely put at least two more lines on increase for potential release in 2015 or 2016.
Impacts
What was accomplished under these goals?
Two experimental lines of wheat are on increase for potential release in 2014. KS061406-LN~37 is a hard red winter wheat with excellent yield potential in central Kansas and is resistance to prevalent races of leaf, stem and stripe rusts. 'Everest' compises 25% of the pedigree and some, but not all, of the tolerances to barley yellow dwarf virus and Fusarium head blight are expressed in the line. KS030887K-6 is a hard red winter wheat with excellent yield potential. It has performed well across the entire state but its short stature may limit its utility in western Kansas dryland conditions. It has excellent milling and baking quality and is resistant to prevalent races of leaf, stem and stripe rusts. One of the parents of this line is a CIMMYT spring wheat that carries race non-specific resistance to leaf and stripe rust. KS030887K-6 carries the markers for Lr46 but the rest of its resistance package is unknown. Several new lines emerging in the program carry race non-specific resistance and almost all crosses are made with at least one non race-specific parent. The impact of this effort is that we are having to focus less on identification and incorporation of new genes for leaf rust and are better able to focus on additional objectives. A doubled haploid population of the cross Art/Everest was phenotyped in the greenhouse. Both parents are intermediate to moderately resistant to Fusarium head blight. The data will be used for QTL analysis. A preliminary evaluation of the data indicates that the resistance in each of the lines is conditioned by different gene(s). A set of 35 lines of wheat that are derived from heat tolerant parents were selected for advancement in 2013. They will be further evaluated and tolerance lines will be used in a doubled haploid program to rapidly produce heat tolerance cultivars. A provision patent was filed on a transgenic approach to heat tolerance. Experiments showed that the expression of a soluble starch synthase gene from rice significantly increased the yield of wheat under heat stress. Additional testing is underway and, since the original construct was in a 'Bobwhite" background that does not retain green leaves under heat stress, the gene is being moved in to cutlivars that do retain green leaf area to see if the effect is enhanced in these backgrounds. In addition, a set of roughly 200 accession of Aegilops geniculata were screened for tolerance to heat. More tolerant accessions will be used as targets for germplasm enhancement. Genomic selection projects for yield in Kansas and grain quality in the CIMMYT program were advanced in 2013. The model for grain quality traits was quite predictive and should allow the prediction of quality without the labor and expense of extensive laboratory analysis. Yield results were less encouraging but there are many refinements that need to be made and additional data that needs to be incorporated into the prediction model. A "breeder versus GS model" is planted in the field for 2014 to determine the efficacy for GS for yield at this point in time. Also, one Ph.D. student complete his degree in 2013 and is currently employed at the Noble Foundation in Ardmore, OK.

OUTPUTS: Experiments at 9 locations across Kansas were conducted and analyzed in support of the breeding program. Data were/will be used for the K-State variety release committee to make decisions regarding release of future K-State varieties. Additional experiments on heat tolerance, genomic selection for yield, genomic selection for quality and high throughput phenotyping were conducted and analyzed as well. Information was disseminated through posters at professional meetings. Four graduate and three undergraduate students were mentored during this time frame. Oral presentations were made at six producer field days in 2012. Presentations were primarily on wheat varieties available to producers and the characteristics of those varieties. A new hard red winter wheat varieties was released and named '1863'. A variety information sheet was prepared and shared with seedsmen who are members of the Kansas Wheat Alliance. Those seedsmen who chose to carry '1863' were allotted seed from Kansas Foundation Seed Service to initiate production of seed that will be for sale in the Fall of 2013.

Martin and Guorong Zhang (KAES WK-ARCH)--Collaboration on testing of experimental materials TARGET AUDIENCES: Producers who may adopt the varieties released from this program and who rely on our program for information. Primary methods of communication include radio interviews, field day presentations, interaction with KAWG and Kansas Wheat Commission, extension publications such as variety performance test results and disease and insect ratings and speaking at various meetings such as the Kansas Crop Improvement Association. Other wheat scientists who work in related areas of wheat research. Primary means of communication is through publication and presentation of results at scientific meetings. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Everest, a 2009 release from the breeding program, was the second leading variety in the state in 2012 and was the leading variety in central and eastern Kansas. Producers were made aware of Everest's attributes by field day presentations and extension publications. Everest has become an important variety in Kansas because of its traits such as Fusarium head blight and resistance to barley yellow dwarf virus that increase productivity and limit risk for Kansas wheat producers. Data we developed in collaboration with Dr. Erick DeWolf was used to educate producers regarding the benefits of fungicide application and identification of conditions when such an application is warranted.

Progress 01/01/11 to 12/31/11
Outputs
OUTPUTS: Field experiments were conducted at eight locations in Kansas under this project. Much of the data were used to facilitate development of new varieties of wheat. Data from three locations were reported by the Variety Testing Program through their website and publication in the High Plains Journal. Extension demonstration strips at two locations were also harvested and data provided to County Extension Agents for distribution to wheat producers. Seven field day presentations were delivered throughout central Kansas. The presentations were focused on attributes of varieties and new research being conducted. A regional wheat workers field day was also held and attracted approximately 80 wheat researchers from the hard winter wheat region. The field day served as an opportunity for exchange of data, discussions regarding continued interstate collaboration, and discussion of critical issues facing the wheat industry. We also filed for and received Plant Variety Protection certificate on 'Everest' wheat. PARTICIPANTS: Allan Fritz (PI) coordinates and leads the project. Andrew Auld, Kim Suther and Robert Steele are Research Scientists on the project who help coordinate and conduct experiments, analyze data and communicate with the public. Adam Krizek, Keely Kiefer and Danielle Hill are undergraduate students who provided labor on this project. TARGET AUDIENCES: The primary target audiences for this project are Kansas wheat producers and member of the wheat industry including the milling and baking industries PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
The primary product of the this research is new wheat varieties. Fuller, a 2006 release, was the second leading variety in Kansas in 2011 and the fourth leading variety in 2012. Everest, a 2009 release, was the fifteenth most popular wheat variety in 2011 and second most planted variety for the 2012 growing season. Everest has a unique set of traits including moderate resistance to barley yellow dwarf virus and Fusarium head blight. Both diseases can cause significant yield loss and there are few varieties that provide resistance. Fusarium head blight also results in the accumulation of mycotoxins in the grain.The rapid adoption of Everest by producers is an indication of the economic value of this combination of traits. Additional benefit is expected to accrue to the milling and baking industry through the reduction of mycotoxins in wheat grain grown in central and eastern Kansas
