PROJECT TITLE: Evaluation of Fall-Seeded Winter Pea and Lentil Cultivars EXPERIMENT NO.: #820703 PROJECT LEADERS: C. Chen, Asst. Prof. of Cropping Systems, CARC, Moccasin, MT D. M.

Neill, Research Associate, CARC, Moccasin, MT J. Vavrovsky, Research Specialist, CARC, Moccasin, MT OBJECTIVES: To evaluate winter survival, performance, and yield of winter pea and lentil variety/breeding lines for grain and forage production potentials in Central Montana's dryland environment. METHODS: Nine winter pea and winter lentil varieties/breeding lines were seeded at the Central Agricultural Research Center (CARC) at Moccasin on October 16, 2002. Information for the test lines is listed on Table 1. Plot dimensions and management practices are shown in Table 2. Plant stands were counted in the fall and spring. Biomass samples were collected approximately a week prior to grain maturity and harvest. Grain was harvested by a plot combine at grain maturity during the period between July 28 and July 31.

Due to the dry summer in 2003, the yields of pea and lentil were generally low and little difference among the breeding lines of peas. Several lentil breeding lines performed superior than others (Table 4).
