Ecological adaptive selection of late-ripening cabbage in the Republic of Dagestan

Due to natural climatic, soil, agroecological conditions, the Republic of Dagestan has the opportunity to grow thermophilic and cold vegetable crops in the spring-summer and summer-autumn periods. As a result of the studies, promising late RIPing white cabbage hybrids were identified for adaptability and stability in the extreme conditions of the mountainous and coastal regions of Dagestan. The research was conducted for 4 years, from 2014 to 2017. The results show that the hybrids under study are diverse in adaptivity. Hybrids Kolobok F1, Astra F1, Aggressor F1 are resistant to stressful abiotic, and are responsive to the beneficial effects of the environment. The latter explains the high value of the regression coefficient (bi> 1). The F1 hybrid is a source of potential productivity, while the Astra F1, the F1 aggressor, is an environmental sustainability. The data obtained by us can be used for the purpose of selection for adaptability.
