In order to highlight the sources of economically valuable traits in 2017-2018 years, 131 varieties of pea collection (Pisum sativum L.) were clustered using a hierarchical agglomerative algoritm based on the minimum of Euclidean distanced. Under conditions with sufficient moisture (2017, GTC=1.35) and moisture deficit (2018, GTC=0.76) in two morphological groups different in leaf type, the varieties were combined into clasters according to similar yield values (g/m2), the protein content in seeds (%) and the duration of the growing season (day) from full germinition to economic maturation. In 2017, in groups with a leafless and a common type leaf, eight clusters were distinguished in each of them, in arid conditions (2018), their number was, respectively, nine and seven. For use in breeding to increase the gross yield of protein, clusters with high yields and protein content are proposed, mainly in the leafless group, which have a higher resistance to lodging. In this morphological group, under conditions with suficient moisture varieties of the sixth cluster Yamalsky, Yamal-2, Aksaysky 55, Stepnyak, Krasnoufimskiy 11, Berkut, Terno with a yield of 380-492 g/m2 and a protein content of 23.23...27.81%, in arid conditions (2018) the varieties of the fifth cluster Faraon, Fokor, L-1599, Pamjat Khangildina, Samarius with indicators, respectively, 268...312 g/m2) and 22.61...22.93% were distinguished. In 2017 among the leaf varieties of the fourth cluster Kudesnik, Argon, L-2516 with the combination of high values of productivity (400...428 g/m2) and protein content in seeds (23.67...25.32%), UG-95888-2, in 2018 varieties of the fifth cluster Intensive 92, Janus, Chishminsky 229 with indicators of 268...320 g/m2 and 22.51...25.42% were distinguished. Varieties Veles and Kazanets with consistently high yields (304-328 g/m2, CV = 0.6 ... 1.3%) are of breeding value as sources of drought resistance

Field studies were conducted in 1973 and 1974 to evaluate the effects of light intensity on the quality and yield of the green field pea (Pisum sativum L.) ’Triumph’. The treatments included a control with no shading (80 klx) and shading with one (31 klx) or two (9 klx) layers of screen material for a 3-wk period before maturity. Shading resulted in a significant decrease in seed weight and yield and a significant increase in protein content of the seed. The effect of shading on viscosity of the cooked samples was quadratic, implying that viscosity only decreased at very high levels of shading. Shading also tended to reduce loss of green color in the seed cotyledons.

Simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] was applied at rates of 0.002–0.800 kg a.i./ha to field peas (Pisum sativum L.) as soil and as foliar applications for 4 yr. Band applications to the soil surface over the seeded rows and incorporated beside the seeded rows in a clay soil had no effect on seed yield or protein content. However, seed yield was increased 25% in the year that seeding was early (3 May) in a fine sandy clay loam, and seed placed into the center of a band into which simazine at 0.4 kg a.i./ha had been rototilled to a depth of 10–12 cm. There were no differences in weight per seed or protein content. Foliar applications were not effective.

Field Peas

Diquat treatments were applied to green-seeded field peas (Pisum sativum L.) over a 5-yr period to determine the effect of applications at various stages of maturity on some agronomic and quality characteristics. The spray application effectively hastened drying of the plants, eliminating the need for windrowing. The rate of 0.28 kg a.i./ha was adequate. The earlier harvesting permitted by the treatments reduced loss of green color and germinability associated with weathering and reduced yield loss from shattering. Applications made as early as the 50% brown pod stage did not markedly affect yield, protein content, seed size, cooking quality or germinability. However, a later stage of spraying may be advisable under conditions of slow maturation.
