Adaptive Potential of Triticale of Different Origins Productivity when Grown under Southern Dagestan Conditions

A study was carried out of the yield and elements of the productivity structure of 32 varieties of hexaploid triticale of various origins from the world collection of VIR. The work was carried out at the Dagestan OS – a branch of VIR, located in the southern flat zone of the Republic of Dagestan. For a comparative study, wheat varieties Nika Kubani and Tanya were used. The study showed that the studied triticale varieties exceeded wheat varieties in terms of such characteristics as: yield, ear length, number of spikelets, grains and grain weight per ear and 1000 grains. However, according to some indicators that determine potential yield, triticale is inferior to wheat – the number of productive stems and the number of grain-free flowers per ear. Based on a complex of economically valuable traits, triticale varieties were identified: PRAGi – 494, 415/3, 479, 468, 483/1, 470/1 and 473/2 (Dagestan), Presto 401 (Poland), Newton (France), TSW 2507 (Germany), which can be recommended as a source material in practical breeding work when creating new varieties with high productivity.
