ASSESSMENT OF GENOTYPES OF YARN BARLEY FROM THE COLLECTION OF VIR FOR ADAPTIVITY AND PRODUCTIVITY UNDER CONDITIONS OF EASTERN SIBERIA

Abstract

The results of a comprehensive assessment were analyzed for 238 samples of the world collection of VIR named after N.I. Vavilov for 2014-2017 years on the yield and the degree of its variation (Cv,%), stress stabil-ity (Уmax-Уmin), ecological stability (St2) and plasticity (bi), relative stability of genotypes (Sgi), general and specific adaptive capacity (GАСi, SАСi), selection value genotypes (SVGi), the adaptation coefficient (CA). It is established that the greatest grain productivity was received from Codac, Etienne, Diamond, AC Albright (Canada), Vaughn C.I. 11367, Kindred (USA), Bagretz (Sverdlovsk region), Ubagan (Chelyabinsk region), Talan, Tanay (Novosibirsk region) and Abalak (Krasnoyarsk territory, Tyumen region). A low coefficient of variation in yield was observed in varieties – Koral (USA), AC Albright (Canada), Domen (Norway), Cirstin (Germany), Asem (Kazakhstan), Nutans 302 (Samara region), Zernogradets 770 (Rostov region) Yasny (Ros-tov region), Novichok (Kirov region), Pervotselinnik (Orenburg region), Tarsky 3 (Omsk region), Abalak (Krasnoyarsk territory, Tyumen region). Among varieties with an increased breeding value of genotypes (SVGi) for the "grain mass with m2" attribute are – AC Albright (Canada), Cirstin (Germany), Talan (Novosi-birsk region), Tarsky 3 (Omsk region), Abalak (Krasnoyarsk territory, Tyumen region). High responsiveness to improving the growing conditions ar noticed among Duplex C.I. 2433, Kindred, Heritage, Hazen (USA), Loyolla, Jackson, BVP-2D-1, AC Stacey, CDC Mc Gwire (Canada), Sv. 66905, Kinnan (Sweden), Mojar (Norway), Bingo Carlsberg (Denmark), M 1913/88 (Czechoslovakia), Olbram (Czech republic), Margret (Germany), Phoenix, Corona, Kozak, Effect, Symphony, Harmony (Ukraine), Hadjibey (Belorussia), Ilek 16 (Kazakhstan), Tonus (Rostov region), Binom (Sverdlovsk region), Raushan (Moscow region), Siberian avangard (Omsk region), Kolchan (Altai region).
