Abstract
There are presented the estimation results (2007-2017) of oat varieties collection of Siberian and Far
Eastern origin in order to select material for new variety producing. There were studied 5 oat early ripening varieties with shoots - waxy ripeness period of 69 - 72 days and 22 medium-ripening varieties with the period of 73 - 76 days. The varieties were study in the nursery on the leached medium-loamy chernozem in the conditions of Priob’e forest-steppe of Novosibirsk Region. Over the years, there was reported a significant variation in economic valuable characteristics for all genotypes. There were revealed genotypes with high ratio value of yield and panicle productivity average for 11 years to the duration of shoots – wax ripeness period. The greatest average yields were formed by the following varieties: Mutik 559 (632 g/ m2 for 71 days); Novosibirsk 88 (630 g/m2 for 72 days; Monar and Bogachkov’s Memory (638 g/m2 and 649 g/m2 for 73 days); Togurchanin and Sig (661 g/m2 and 649 g/m2 for 74 days); Orion (675 g/m2 for 75 days) and Malysh (686 g/m2 for 71 days). The varieties showed the highest ratio value of the yield to the duration of shoots - wax ripeness period in comparison with the varieties equal in development velocity. Polar correlation indices between shoots - wax ripeness period and productivity were demonstrated by studied varieties of Coryphaeus (r = 0.39 with 609 g/m2 average productivity) and Talisman (r = 0.83 with 671 g/m2 average productivity) and the same varieties showed polar indices of correlation between shoots – wax ripeness period and panicle grain mass (r = 0.18 and r = 0. 80 respectively). Correlation coefficients variation of the varieties confirms a great genotypes influence on development duration and plant productivity. The promising varieties were selected: Mutik 559, Novosibirsk 88, Monar, Bogachkov’s Memory, Togurchanin, Sig, Orion and Malysh on optimal combination of yield and duration of shoots-wax ripeness period; Tayozhnik, Monar, Bogachkov’s Memory, Sig, Orion and Altai coarse- grained on optimal combination of panicle productivity and duration of shoots - wax ripeness period.
