PROJECT TITLE: Evaluation of fall seeded winter pea and lentil line performance. (Western Regional Winter Dry Pea and Lentil Evaluation Trials) EXPERIMENTS: 8207 & 8407 PROJECT LEADERS: D.M.

McPhee, Breeder, USDA-ARS, Pullman, WA R.W. Short, Agronomist, USDA-ARS, Pullman, WA J. Vavrovsky, Research Specialist, CARC, Moccasin, MT OBJECTIVES: To evaluate winter hardiness of fall seeded winter dry pea and lentil lines. METHODS: Winter dry pea and winter lentil trials were seeded September 26, 2006 into winter wheat stubble. The winter pea trial consisted of 16 winter pea lines from the USDA-ARS dry pea breeding program at Pullman, Washington and one Austrian winter pea (Granger; Table 1). The winter lentil trial consisted of 21 winter lentil lines from the USDA-ARS program and one Montana State University winter lentil release (Toni; Table 1). Biomass samples were collected at the 2-4 podded node stage. Grain harvest was conducted in mid- to late-July (see Table 2). Table 2 provides additional agronomical information. RESULTS: Dry Pea Winter Survival: A difference in spring stand (visual evaluation) amongst the winter pea lines was exhibited, with Granger Austrian winter pea having the best stand, but was significantly similar to five other lines (Table 3). Forage Biomass: When cut at the 2-4 podded nodes growth stage, dry matter forage production averaged 2,810 lbs acre-1 (Table 3). The yellow winter pea, Windham, produced the most dry matter (3,512 lbs acre-1), but was not significantly different (based on LSD0.05) than seven other lines. Grain Production: The winter pea trial averaged 1,851 lbs acre-1 of grain production (Table 3). Windham yellow pea showed the highest production (2,309 lbs acre-1), but had a similar yield (based on LSD0.05) to line PS9830F011 yellow pea. Seed Weights: The trial had an average test weight of 64.4 pounds per bushel (Table 3) with line PS0230F092(a) smooth green pea having the heaviest weight (66.1 lbs bu-1). One thousand kernel weights for the trial averaged 135.4 grams, with line PS0230F092(a) having the largest size with 151.1 grams per 1,000 kernels, which was similar in size (based on LSD0.05) to lines PS03101150 and PS03101160 smooth green peas. Lentil Winter Survival: Upon visual observations, large differences in winter survival among the winter lentil lines were observed (Table 4). Turkish-type (“T”) lines LC02600449T and LC03600295T had the poorest spring stands with an average score of 1.6 and 1.8 (out of possible of 5), respectively. Forage Biomass: Only lines, which showed visible potential for biomass production, were harvested. Those lines harvested had an average dry matter production of 1,657 lbs acre-1 at the 2-4 podded nodes stage (Table 4). Line LC9979062 lentil had the most forage production (2,266 lbs acre-1), but was significantly similar to (based on LSD0.05) four other lines. Grain Production: The lentils averaged 1,147 lbs acre-1 seed production (Table 4). Line LC9977116 had the highest grain yield (1,475 lbs acre-1), but was not significantly greater than six other lines (including Morton). Seed Weights: The winter lentil’s test weights averaged 65.8 lbs bu-1 (Table 4), with line LC03600232T being the heaviest (67.2 lbs bu-1). Seed size ranged from 24.5 (WA8649090) to 46.9 g 1,000 kernels-1, with line LC9440070R having the largest seed (significant, based on LSD0.05). Future Plans: Evaluation of winter hardy lines of dry pea and lentils will continue at CARC, with the continued hope of releasing lines suitable for forage and seed production in Central Montana’s environment.
