What was accomplished under these goals?
Over the last five years, significant and substantial accomplishments were made towards thethree major goals of the project: 1) Newmethodologies to improve plant improvement were developed and applied; 2) Maize was improvedthrough breeding for South Central states, and 3) future generations of plant breeders and quantitative geneticists were educated and trained. However, within a five year project, these remain far from solved problems and substantial work, including new tools and technologies are needed to makeprogress overfuture years. Objectives Molecular Quantitative Genetics G1: Genetic relationships among grain maize lines were identified as were loci from using arious genetic mapping techniques for relevant phenotypic traits.G2: The genetic basis of yield, agronomic and specialty traits in maize wasinvestigated in newly developed populations. G3: The genetic basis of tillering ability, perennial growth habit and photoperiod sensitivity in the C4 grasses: maize, sorghum were better understood through newly developed populations ( given the timeline, these publications will be reported in future projects).G4:Computer simulations to increase knowledge for protocols of genetic investigation and plant breeding methodology (to be published next year) Maize Breeding for South Central States B1:Exotic maize alleles were introgressed into elite germplasm to increase the genetic diversity of US maize germplasm.B2:Yield, resistance to biotic (mycotoxins- especially aflatoxin) stress and tolerance to abiotic stresses (salinity, drought and heat) were improved through breeding in addition to charecterizations using genetics.B3:Maize inbred lines and populations processing improved quality attributes and properties for foods, feeds, and industrial products were produced, while enhancing agronomic characteristics for Texas growing regions.B4:Molecular techniques such as marker-assisted selection (MAS) were used to facilitate the selection of photoperiodism, an economically and agronomically important trait. Education E1:Fraduate students were involved on various projects for training and experience.E2:Projects were jointly developed and initiated by graduate students to deliver scientifically well-rounded, self-motivated and confident leaders of breeding and genetics for the future. Techniques:To accomplish these objectives in an effective manner, techniques were first developed for the program that reduced burdens in cost, labor and time.T1: Appropriate genetic marker screening platforms were selected.T2: Data handling pipelines to track and link germplasm with phenotypic and genotypic information were developed and used.T3: Methods of rapid phenotypic analysis, such as near infrared spectroscopy (NIRS) and automated field and laboratory based machines were developed.T4:Technologies that increasedthe speed of a reproductive and breeding cycle (CoGiV) were attempted, but deemed to be too difficult given program resources. T5:Improved methods to evaluate and increase safety in the handling of aflatoxin contaminated material were developed and evaluated.

Impacts
What was accomplished under these goals?
Activities in all proposed objectives were accomplished as evidenced by publications as well as presentations and students trained. Multi-disciplinary approaches in high throughput field-based phenotyping (HTFP) for maize breeding using unoccupied aerial vehicles / systems (UAV / UAS / i.e. drones) remained a major research focus. Students and colleagues worked on improving UAS measures as well as to conduct new measurements with this data. New approaches to data analysis and reanalysis were attempted to make better decisions in the program. Maize populations, inbred lines and hybrids were advanced for improving aflatoxin, yield, and/or other traits for Texas and southern US farmers. Elitelines were increased and both crossing blocks and isolation blocks were employed to create hybrids for future testing. Experimental hybrids were tested in replicated multi-location trials. The three SNP markers validated previously to increase yield in testcrosses were tested as heterogeneous inbred families (HIFs) and found to work in multiple biparental population backgrounds.NIRS calibrations were used, improved and applied to other genetic mapping and breeding germplasm. Additional progress was made on understanding GxE through the southeast regional aflatoxin trials (SERAT), genomes to fields projects, and a photoperiod sensitivity project supported by the Texas Corn Producers Board. A paper on the collaborativemaize ATLAS project was published. Perennial sorghum, perennial maize and colored (red, blue, purple) maize populations and germplasm were all advanced.

All personnel attended multiple professional and research seminars throughout the year and some presented their work at regional or national conferences includingthe ASA/CSSA/SSA meeting, the National Association of Plant Breeders meeting, two NIFA FACT meetings, and other local meetings. Personnel were introduced to outside visitors and encouraged to meet one on one. David Rooney, program staff, was awarded the Department of Soil and Crop Sciences Laboratory Support Staff award for his excellent work for the Department and in the seed lab. How have the results been disseminated to communities of interest?Scientists and colleagues were reached through presentations, publications, and collaborative research activities. Graduate and undergraduate students were reached through formal classroom instructions and in assisting and leading independent research projects. Farmers/ producers were reached through presentations, publications, field days and on-farm research.

The public was reached through popular press presentations, publications and social media. What do you plan to do during the next reporting period to accomplish the goals?Many of the same projects will continue in the next reporting period so that additional data can be collected and breeding material advanced. Emphasis in developing and usinghigh-throughput field phenotyping (HTFP) will focus increasingly on unmanned aerial vehicles and systems (i.e. UAVs, UASs, drones) and the analysis and use of the large datasets that result. Not much emphasis onnovel ground vehicles will be undertaken.Breeding program and genetic mapping activities will continue as proposed. Emphasis on graduate student training and undergraduate experiances will continue. Emphasis will continue to be placed on data management, data analys and data analytics of existing data (primarily phenotypic) as well as improving data science abilities and automation in both research and teaching.
Impacts
What was accomplished under these goals?
Multi-disciplinary approaches in high throughput field-based phenotyping (HTFP) for maize breeding using unmanned aerial vehicles / systems (UAV / UAS / i.e. drones) remained a major research focus. Aninbred genetic mapping population wasevaluated with standard agronomic measurements but also subjected to weekly UAS flights by both fixed wing and rotary wing aircraft. Data are still being analyzed but we found and published some relatedwork on UAS.The ground vehicle was operated very infrequently due to mud and lack of an operator with availible time. Students and colleagues worked on improving these measures as well as to conduct new measurements with this data. New approaches to data analysis and reanalysis were attempted to make better decisions in the program. The UAS approach was furthered by USDA NIFA-AFRI project funding to expand these HTFP approaches to three different management plantings of the genomes to fields (G2F) project. HTFP technologies remain verypromising but will require a large investment and multi-disciplinary collaborations to make the data collected useful to plant breeders. Different populations were advanced for improving aflatoxin, yield, and/or other traits for Texas and southern US farmers. Elite lines were increased and both crossing blocks and isolation blocks were employed to create hybrids for future testing. Experimental hybrids were tested in replicated multi-location trials. The threeSNP markers validated previously to increase yield in testcrosses, continued to be backcrossed by an undergraduateinto different backgrounds to create near isogenic lines as a research project. NIRS calibrations were used, improved and applied to other genetic mapping and breeding germplasm. Additional progress was made on understanding GxE through the southeast regional aflatoxin trials (SERAT), G2F, and the maize ATLAS project. Perennial sorghum, perennial maize and colored (red, blue, purple) maize populations and germplasm were all advanced.

Impacts
What was accomplished under these goals?
Greater emphasis continued to be made developing and applying multi-disciplinary approaches in high throughput field-based phenotyping (HTFP) for maize breeding using ground vehicles and unmanned aerial vehicles / systems (UAV / UAS / i.e. drones). For the second year an approximately 30 entry hybrid test and an inbred genetic mapping population were evaluated with standard agronomic measurements but also subjected to weekly UAS flights by both fixed wing and rotary wing aircraft; the ground vehicle was operated very infrequently due to mud. Data are still being analyzed but we found and published that UAV plant height had good repeatability and good correlations with manual measurements. Students and colleagues are working on improving these measures as well as to conduct new measurements with this data. New approaches to data analysis and reanalysis were attempted to make better decisions in the program. The UAS approach was furthered by USDA NIFA-AFRI project funding to expand these HTFP approaches to three different management plantings of the genomes to fields (G2F) project. HTFP technologies are very promising but will require a large investment and multi-disciplinary collaborations to make the data collected useful to plant breeders. Many different populations were advanced for improving aflatoxin, yield, and/or other traits for Texas and southern US farmers. Additionally elite lines were increased and both crossing blocks and isolation blocks were employed to create hybrids for future testing. Many experimental hybrids were tested in replicated multi-location trials. We confirmed three SNP markers increase yield significantly in testcrosses, and in inbred lines per se; an undergraduate has been backcrossing these into different backgrounds to create near isogenic lines as a research project. NIRS calibrations were used, improved and applied to other genetic mapping and breeding germplasm. Additional progress was made on understanding GxE through the southeast regional aflatoxin trials (SERAT), G2F, and the maize ATLAS project. Perennial sorghum, perennial maize and colored (red, blue, purple) maize populations and germplasm were not advanced this year but will be next year.

Personnel were introduced to outside visitors and encouraged to meet one on one. How have the results been disseminated to communities of interest?Results were disseminated through: peer reviewed publications, oral/ poster presentations at regional or national meetings, one on one meetings, webpages, social media,graduates with jobs, and other informal interactions. What do you plan to do during the next reporting period to accomplish the goals?There will continue to be an increasingemphasis in developing and usinghigh-throughput field-based phenotyping (HTFBP), including novel ground vehicles and UAVs, and analysis and use of the large datasets that result.The breeding program and genetic mapping activities will continue as proposed. There will be continued focus oncommercializing successful material and participating in larger cooperative projects: southeast regional aflatoxin trials (SERAT), the genotypes to fields initiative (G2F), the maize ATLAS project, etc.
Impacts
What was accomplished under these goals?
A greater emphasis than past years was made on developing and applying multi-disciplinary approaches in high throughput field-based phenotyping (HTFP) for maize breeding using ground vehicles and unmanned aerial vehicles (UAVs / drones). A fourreplicate20 to30 entry hybrid test was planted and subjected to HTFP and conventional yield and agronomicphenotyping throughout the growing season in four environments across Texas; an inbred genetic mapping population was also subjected to the same approaches. Data are still being analyzed but plant height had good repeatability and good correlations with manual measurements. These technologies are very promising but will require a large investment and multi-disciplinary collaborations to make the data collected useful in plant breeding. Many different populations were advanced for improving aflatoxin, yield, and/or other traits for Texas and southern US farmers. Additionally elite lines were increased and both crossing blocks and isolation blocks were employed to create hybrids for future testing. Many experimental hybrids were tested in replicated multi-location trial. Additional progress was made on confirming three SNP markers that increase yield significantly in testcrosses, it was discovered that these SNPs also have an effect in inbred lines per se.NIRS calibrations were improved and applied to other genetic mapping and breeding germplasm. Additional progress was made on understanding GxE through the southeast regional aflatoxin trials (SERAT), the genotypes to fields initiative (G2F), and the maize ATLAS project. Perennial sorghum and perennial maize populations and germplasm were further advanced.?

Progress 12/08/14 to 09/30/15
Outputs
Target Audience:Undergraduate and graduate students were reached through both formal classroom instruction and in assiting and leading independent research projects. Other scientists were reached through presentations, publications and collaborative research activities. Farmers/ producers were reached through presentations, publications, field days and on-farm research. The public was reached through presentations, publications. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?All employed personnel were pursuing a degree (graduate students and technical support were pursuing MS or PhD, undergraduates were pursuing BS) and took classes; visiting scholars sat in on classes. All personnel attended multiple professional seminars throughout the year and some presented their work at regional or national conferences. Personnel were introduced to outside visitors and encouraged to meet one on one. How have the results been disseminated to communities of interest?Results were disseminated through: peer reviewed publications, oral/ poster presentations at regional or national meetings, one on one meetings, webpages, graduates with jobs, and other informal interactions. What do you plan to do during the next reporting period to accomplish the goals?The breeding program and genetic mapping activities will continue as proposed. Additional focus will be made on commercializing successful material and participating in larger cooperative projects: southeast regional aflatoxin trials (SERAT), the genotypes to fields initiative (G2F), the maize ATLAS project, etc. Additionally, there will be a much stronger focus on high-throughput field-based phenotyping (HTFBP) and analysis and use of the large datasets that result.
Impacts
What was accomplished under these goals?
Many different populations were created and advanced for improving aflatoxin, yield, and/or other traits for Texas and southern US farmers. Progress was made on confirming three SNP markers that increase yield significantly in testcrosses. A large genetic mapping population detected multiple new loci (QTL)for traits such as height, flowering time and leaf rolling. NIRS calibrations were improved and applied to bother genetic mapping and breeding germplasm. Progress was made on understanding GxE through thesoutheast regional aflatoxin trials (SERAT), the genotypes to fields initiative (G2F), and the maize ATLAS project. A large multi-disciplinary project on unmanned arial vehicles/systems (UAV/UAS) was pursued to better phenotyping the germplasm in the field.
