Research Project: Developing Improved Varieties of Peas, Lentils, and Chickpeas for Growers in the United States

Location: Grain Legume Genetics Physiology Research

Project Number: 2090-21000-034-004-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Dec 1, 2016
End Date: Nov 30, 2021

Develop and release improved cultivars of pea, lentil, and chickpea that are adapted to existing and emerging areas of production for cool season grain legumes in the U.S.

Cyclical hybridization including single, double and triple crosses will be conducted to combine favorable alleles for traits of interest. Parental lines will include adapted germplasm, commercial cultivars and germplasm accessions from the various international germplasm repositories. Parents will be selected based on their performance for traits of existing and emerging importance, including yield, resistance to selected diseases, seed quality, early maturity, and winter hardiness. Generational increases of populations will be conducted in field and greenhouse environments. Select populations and breeding lines will be increased at counter-season nurseries. Promising lines, populations, and check cultivars will be evaluated in replicated field plots in preliminary yield trials in Washington. Entries that exhibit excellent performance in preliminary yield trials will be tested in replicated advanced yield trials that are conducted annually at several locations in Washington and Idaho. All yield trials will be conducted using conventional management practices for weed and pest control. The most promising advanced breeding lines will be distributed to cooperators in Washington, Idaho, and other states in the U.S. for independent evaluation in regional yield trials. The decision to release a promising breeding line as a new cultivar will be based on a rigorous comparison of its performance relative to that of commercial check varieties representing appropriate market classes. Decisions regarding the release of new cultivars will be made following consultations with cooperating researchers, growers, processors, industry representatives, and the USDA, Agricultural Research Service (ARS) Office of National Programs and Office of Technology Transfer.
