ASSESSMENT OF SPRING TRITICALE ADAPTIVE FEATURES IN KHABAROVSK REGION

Abstract

The article evaluates the adaptive properties of collection samples of spring triticale in terms of grain yield. The studies were carried out in 2015-2021 on the experimental fields of the Far Eastern Research Institute of Agriculture (Khabarovsk region). The object of research is 21 collection samples of spring triticale. On average, over the years of research, varieties with the maximum grain yield AC Certa (3592), Lana (3630), Uzor (3888), Zolotoy grebeshok (3677) were noted – 36.0-36.6 c/ha. As a result of the research, promising samples were identified in terms of adaptability parameters: adaptability coefficient (KA?1.00) – AC Certa (3592), Lana (3630), Dagvo (3645), Zolotoy grebeshok (3677), Uliana (3887), Uzor (3888 ), Lotos (3889), Mykola (3890), Kаrаvai kharkоvsky (3892), Yarilo (3895); plasticity index (IP?1.10) – AC Certa (3592), Lana (3630), Zolotoy grebeshok (3677); stability index (IS?3.00) – Victoria (3922); intensity index (II?2.00) - Yarilo (3895); genotypic effect (Ei?5) – AC Certa (3592), Lana (3630), Zolotoy grebeshok (3677), Uzor (3888); homeostaticity (Hom?4) – Victoria (3922), Zgurivsky (3960); breeding value (Sc?10) – Victoria (3922), Zgurivsky (3960), Sandio (3988). Triticale genotypes are divided into 2 groups: varieties of intensive type - Ukro (3644), Scoriy (3676), Pamyat Merezhko (3916), ZG 186 (3907), Rovnya (3935), Oberig kharkovsky (3961), Victoria (3922), Sandio (3988), Kobzar (3958), Tleridal (3986), Losinovske (3959), Zgurivsky (3960); and extensive type – AC Certa (3644), Uzor (3888), Lana (3630), Zolotoy grebeshok (3677), Dagvo (3645), Mykola (3890), Yarilo (3895), Kаrаvai kharkоvsky (3892), Ulyana (3887 ), Lotos (3889).
