Badanie przebiegu wegetacji i cech użytkowych rodów soi korelatywnie związanych z plonem nasion [The studies on vegetation period and plant characters determining seed yield in soybean]

Jerzy Szyrmer

Abstract


12 Soybean strains bred by the author were tested with respect to their adaptation to different environments in the period 1975-1977. Better environmental conditions in Przecław (Rzeszów region) than in Radzików near Warsaw have beneficial effect on seed yield and the lenght of vegetation period in tested soybeans. Generaly, tested strains yielded better than population variety 'Warszawska' used as a check. Highest yield was produced by strain M-17/76 - 22,7 q/ha. This strain is already registered as a variety 'Ajma'. Seed yield, fat and protein content are determined by genotype and environmental factors. The negative correlation was found between seed yield, its components and the length of vegetation period. It suggests that selection of early and, at the some time, high yielding varieties can and should be done.
