Progress 10/01/17 to 09/30/18
Outputs Target Audience:The target audience for this project are breeders and dry bean seed companies seeking to deliver stress-tolerant bean lines for producers across the world. A secondary audience would be agronomists needing the latest and highest-yielding cultivars and consumers interested in food quality related to the different cultivars. Changes/Problems:We did not have any major problems except for hail storms that compromised the yield results at Lingle in 2018. Heitholt moved his project to Powell, WY, which is in the heart of Wyoming's bean seed production region so this will be an advantage going forward. What opportunities for training and professional development has the project provided?Heitholt is on the receiving end of multiple learning experiences. These are primarily obtained during the annual W-3150 meeting and tours. On alternate years at the Bean Improvement Cooperative, the experience is a bit more intense. During the summer of 2018, Heitholt attended the W-3150 meeting at UC-Davis (CA) and learned about lygus on lima bean and drone (NDVI) evaluation of different bean progeny. How have the results been disseminated to communities of interest?Heitholt provided his MRPN and CDBN findings to the respective coordinator and has distributed his local CDBN data to bean producers and handlers in Wyoming. The Wyoming Bean Commission also received a copy of Heitholt's progeny results. The findings from 2018 will be published in the Wyoming Agricultural Experiment Station Field Days Bulletin. What do you plan to do during the next reporting period to accomplish the goals?Heitholt plans to advance his breeding lines in the field at Powell, WY during 2019. In 2018, we performed a seed increase on 15 advanced lines at Powell and about 15 more at Lingle. Crosses will continue to be made during the winter and spring months of 2019 in order to establish lines that have good agronomic traits. Breeding and evaluation of popping lines is also continuing in 2019 in collaboration with food scientists in Laramie. Heitholt will attend the BIC meeting in Fargo (ND) in 2019.
Impacts What was accomplished under these goals?
Some of the progeny from different crosses performed well in Powell and Lingle, WY. In Powell, three progeny lines outyielded the commercial checks so those lines are going to be studied again in 2019. These are pink and pinto lines. Multiple lines that under-performed were discarded. Jim Heitholt is participating in the regional Dry Bean Drought Nursery (DBDN), Midwest Regional Performance Nursery (MRPN) trials and the national Cooperative Dry Bean Nursery (CDBN) trial. All three of these tests were grown at Lingle and the CDBN was also grown at Powell. Three local entries that were grown in the Powell CDBN outperformed the 21 standard entries. Heitholt also collaborated in a test of three pinto genotypes, with three levels of irrigation, five seeding rates, and two row spacings grown at Lingle and Powell. Results of that test were mixed but it appeared that 50K plants per acre might be an adequate stand in some environments. Heitholt is also evaluating popping beans. Heitholt found that variation in canopy temperature among popular cultivars is correlated with yield with the yield higher for cultivars with cooler canopies. The idea is to predict and identify high yielding genotypes and possibly forego measuring yield during selection if the number of plots and lines are too many or accurate yield numbers are lost due hail or other events. During the winter months in the greenhouse, the parents (the tropical photoperiod sensitive lines along with adapted types) are grown in the greenhouse and crosses or backcrosses are being made.

Progress 10/01/16 to 09/30/17
Outputs Target Audience:Our target is dry bean seed companies and fellow plant breeders. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?One postdoc and one undergraduate participated in this project. These two individuals were trained in taking ecophysiological measurements of dry bean plants and canopies. How have the results been disseminated to communities of interest?The results from 2016 were presented in the Bean Improvement Cooperative Reports, at a Wyoming Bean Commission meeting, and in the Wyoming Agricultural Experiment Station Field Day Bulletin. Results from 2017 were presented to the Wyoming Bean Commission in early February 2018. What do you plan to do during the next reporting period to accomplish the goals?We expect to perform a replicated yield test with the advanced lines generated from the crosses listed above. Progeny from numerous crosses are being advanced and will be grown plant-to-row in 2018. In 2018, we will also conduct the Lingle and Powell sites for the Cooperative Dry Bean Nursery and for the Dry Bean Drought Nursery.
Impacts What was accomplished under these goals?
Nineteen F4-lines from a cross between Long's Peak and UI 537 were grown and three locations. In one location, the lines were grown under full irrigation and under drought stress. Results are still being analyzed as of January 2018. We also grew the Cooperative Dry Bean Nursery at two Wyoming locations, Lingle and Powell. Results were submitted to the CDBN coordinator and will be published during 2018. Numerous crosses were made and F1 seed is being grown in the greenhouse during January 2018. Other F3 lines from crosses made in 2016 and 2017 are going to be grown in the field in 2018. At Lingle, WY, we grew 33 advanced lines from other breeding programs in what is called the Dry Bean Drought Nursery. All 33 lines were grown under full irrigation and deficit irrigation. Samples are still being processed as of February 2018.

Progress 10/01/15 to 09/30/16
Outputs Target Audience:The target audiences for this multi-state project are dry bean breeders throughout the world and domestic seed companies that market bean varieties. Other audiences include pathologists, weed scientists, molecular biologists, and food scientists. Changes/Problems:In 2016, a hail storm destroyed five dry bean tests at Lingle (WY). We did not have any experimental material at that site but we lost a chance to evaluate would-be parental material. What opportunities for training and professional development has the project provided?Our program is training one Ph.D. student and one undergraduate student. The Ph.D. student is screening released cultivars and accessions from the USDA Phaseolus vulgaris Collection for tolerance to low soil N. Our undergraduate student is screening cultivars for drought tolerance. Each student is learning how to measure agronomic and ecophysiological traits as well as culturing rhizobia strains that are used in our research. How have the results been disseminated to communities of interest?The results are disseminated primarily through the Wyoming Agicultural Experiment Station Field Days Bulletin, the Bean Improvement Cooperative Annual Reports, and in-person at field days held in July at Powell (WY) and in August at Lingle (WY). What do you plan to do during the next reporting period to accomplish the goals?In 2017, we will screen newly developed lines from other breeding programs for drought tolerance and tolerance to low soil N. We expect to test 20 F4 lines derived from a cross between a Colorado State pinto cultivar and a University of Idaho pink bean. Seed from single plant selections will be advanced and tested again in 2018. We continue to make crosses with not only elite material but also accessions from the Phaseolus Collection that might bring in new drought tolerant genes.
Impacts What was accomplished under these goals?
For Wyoming in 2016, we screened dry bean genotypes for tolerance to drought and low soil nitrogen. At Powell (WY) and Lingle (WY), we conducted one location each of the Cooperative Dry Bean Nursery. At Lingle only, we conducted the Drought-Tolerance Nursery. At Powell, the yield results of the CDBN nursery are not yet available as of early December 2016. At Lingle, the CDBN was lost to hail as were all other tests. At Powell, genotypic variatio n (36 genotypes) in seed yield was negatively correlated with canopy temperature. This 2016 observation confirmed what our lab in Wyoming observed in 2015. How we might use canopy temperature as a selection tool going forward is unclear at this time but it remains an excellent opportunity.
