Results of ecological testing of spring barley varieties in the southern forest-steppe of the Southern Urals

Abstract. The aim of the research was to adjust direction barley breeding towards creation semi-intensive and intensive varieties, for farms with different levels agricultural culture, according economically valuable characteristics adapted conditions Chelyabinsk region. An assessment ecological testing spring varieties in southern forest-steppe zone Southern Urals during sowing fallow grain predecessor 2018 – 2020 parameters adaptability yield carried out. Methods. studies were conducted from 2020. In region, GP “Troitskoe”. A detailed analysis is given: coefficients environmental index (Ij), adaptation, genetic flexibility, plasticity (bi) stability (2d) are calculated. selection all studied obtained. Results. results this test showed that whole set, have high period: Omsk 95, Orda, Nutans 236C158, 272F677, 193C93 an coefficient greater than 1. Nutans193C93 maximum 3 years when predecessor, they had a consistently adaptation 1 under any weather conditions. increase flexibility found pairs 1.61 3.09. For risky farming, most plastic potential distinguished: 207C74. Pallidum 297C151, 99, 96 103G177 reacted sharply changes vegetation Scientific novelty Groups been identified stability, simplifying further process. Varieties 99 Vakula can be used drought resistance.
