2012 Annual Report 1a.Objectives (from AD-416): Conduct advanced lentil, pea, and chickpea yield trials in several locations in MT and ND. 1b.Approach (from AD-416): Locations will include Kalispell, MT, Moccasin, MT, Carrington, ND, Hettinger, ND and Minot, ND. Lentil advanced yield trials will include approximately 20 advanced breeding lines, which will be selected based on performance in the Advanced Yield Trials conducted in WA and ID by the USDA-ARS Grain Legume Genetics and Physiology Research Unit (Pullman, WA). These will include the four highest yielding advanced breeding lines for each major market class (Pardina, Eston, Turkish Red, and Large Seeded Green). Lentil checks will include the varieties Eston, Pardina, Crimson, and Riveland. Kabuli chickpea advanced yield trials will include approximately 10 advanced breeding lines, which will be selected based on performance in the Advanced Yield Trials conducted in WA and ID by the USDA-ARS Grain Legume Genetics and Physiology Research Unit (Pullman, WA). Chickpea checks will include the varieties Dwelly, Troy, Sierra and Dylan, which represent high yielding varieties of both the Café and Spanish White Kabuli classes. Pea advanced yield trials will include approximately 10 advanced green pea breeding lines and 6 advanced yellow pea breeding lines, which will be selected based on performance in the Advanced Yield Trials conducted in WA and ID by the USDA-ARS Grain Legume Genetics and Physiology Research Unit (Pullman, WA). Green pea check varieties will include Aragorn, Ariel, Columbian and Medora, while the yellow pea checks will include Universal and Carousel. Each entry will be grown in 6 ft x 20 ft plots with three replications per entry per location. Recommended management practices will be employed at each location with respect to seedbed preparation and the control of weeds and insect pests. Data on days to flower, days to maturity, plant height, seed size (gm/100 seed) and yield will be collected for each entry. Tolerance to lodging will be inferred from the ratio of plant height at maturity/plant height at harvest. Appropriate statistical analysis will be conducted to detect significant differences among entries for each data class. 3.Progress Report: Several pea, lentil and chickpea advanced breeding lines and check varieties were evaluated across multiple locations in Montana and North Dakota. Two lentil lines, LC01602300R and LC01602273, produced yields that greatly exceeded that of their respective comparative check varieties, Richlea and Eston. Breeder seed of LC01602300R is being produced at the present time. The results of this project relate to Subobjective 1A (Develop pea, lentil and chickpea cultivars with broad adaptation to diverse production environments and with resistance to fungal and viral pathogens) of the in-house associated project. ARS PI monitoring activities to evaluate research progress included: phone calls/conference calls, on-site Cooperator/ARS meetings, email communications, discussions at professional conferences/meetings, discussions at annual workshops/conferences, review of Accomplishment Report.
