Abstract
In the conditions of the steppe zone of the Orenburg Urals, varieties of the forest Northern Russian ecological group formed 6-10 leaves; varities of West Siberian forest-steppe - 5-12 leaves; varities of East Siberian forest - 6-10 leaves; eastern forest-steppe and Volga steppe - 7-10 leaves; eastern steppe - 7-12 leaves; southern steppe - 5-10 leaves and Chinese - 6-9 leaves. The greatest number of leaves formed varieties of West Siberian forest-steppe and steppe eastern ecological groups. In arid years, the greatest variability was noted in varieties of Tyumenskaya 25, Omskaya 23, Sibirskaya 16 (forest-steppe West Siberian eco-type); Vatan, Chelyba zolotistaya (forest-steppe eastern ecotype); Spurt, Margarita (steppe Volga ecotype); FPR-Ppd-s0 (forest North-Russian ecotype); Taezhnaya Niva (forest East Siberian ecotype); Aktyube 19, Ishimskaya 92 (steppe eastern ecotype). In the unfavorable years of water availability, the period of the “flag” leaf life was longer in the varieties: Aktyube 3, Ishimskaya 92, Omskaya 36, Riks, Saratovskaya 29, Saratovskaya 66, Saratovskaya 70, Saratovskaya 74, Solomiya, Tulaykovskaya 105, FPCh-Rdd-0, FPCh-Ppd-s0, FPCh-Ppd-w0 and Shortandinka 95.
