BREEDING INDICES IN THE EVALUATION OF WINTER RYE VARIETIES

the purpose of the study is to evaluate the role of breeding indices in assessing the yield of winter rye varieties in the open forest-steppe of the Krasnoyarsk Territory. The research was conducted in 2022 in the fields of the breeding crop rotation of the Krasnoyarsk Research Institute. The material was the varieties of winter rye Yeniseika, Krasnoyarskaya universalnaja and Arga. The ratio of the mass of grain from the ear to the height of the plant; to the length of the ear; to the length of the upper internode; to the mass of the ear; the ratio of the mass of the main ear to the mass of the straw of the main stem; the ratio of the number of grains in the ear to the length of the shoot; the ratio of the mass of the stem to the height of the plant. The most productive and lodging-resistant Arga variety was characterized by the highest breeding indices: Mexican, Canadian, Poltava, intensity.
