Evaluation of oat varieties adaptive properties by productivity in the Priobskaya forest-steppe zone

Abstract

The results of evaluation of adaptive properties of released oat varieties of Siberian breeding by yield in the Priobskaya forest-steppe of Novosibirsk region are presented. The experiment was conducted on the experimental field of the Siberian Research Institute of Plant Production and Breeding in 2012-2021. The object of the study were 37 oat varieties included in the State Register of the Russian Federation and released in the West Siberian (№ 10) and East Siberian (№ 11) regions. Yield estimation and phenological observations were carried out according to the methodology of N.I. Vavilov All-Russian Institute of Plant Genetic Resources. For statistical data processing the method of B.A. Dospekhov was used. Potential productivity and adaptability of the varieties were determined by L.A. Zhivotkov et al. method, resistance of the varieties to stress conditions - by A.A. Goncharenko, the yield spread - by V.A. Zykin. Analysis of yields by groups of ripeness showed a natural tendency: as the growing season lengthens by groups of ripeness, the productivity potential also increases. The following varieties had high indicators of productivity potential in favorable years and adaptability to adverse environmental factors: Krasnoobsky, Mustang, Metis, Oven, Otrada, Talisman, Irtysh 21, SIR 4, Orion. The varieties Oven, Novosibirsk 5, CIR 4 showed high adaptability and stability. Four varieties were characterized by the ability to give not the maximum, but high stable yield under any conditions: Krupnozerny, Novosibirsk 88, Belozerny, and Korifey.
