Аннотация

Under conditions of the Volga-Vyatka region, which is characterized with the short cool growing season with unstable mode of moistening, 136 acces-sions of covered oats are studied in 2016-2018 on duration of growing sea-son and productivity for the purpose of specification of their classification by precocity, selection of sources for use in breeding on adaptability. Groups of genotypes are determined by precocity: early - the growing season is 65 - 80 days, mid-season – 74-88 days, middle-late - 79-93 days, late-ripening – 80-103 days. It is established that duration of period «seedlings - wax ripeness» is stable in these groups; correlation coefficients in pairs between 2016, 2017 and 2018 years of researches were significant positive (r = 0.60-0.87). The index of productivity was less stable; the dependence of productivity on the growing season varied from weak to average significant (r = 0.25-0.45). The mid-season sources are selected forming stable productivity regardless of a condition of agro-climatic resources: k-3624 II-4032-15C-8C-1C-OC, k-3717 CEV/OBS/PAR, and k-3754 AGA/ESM/SAI//CHI/OBS
