The study presents the results of the research on the productivity features and adaptability parameters of domestic corn hybrids under different irrigation modes and water supply under conditions of the Arid Steppe.
The research object was modern corn hybrids of domestic selection of different maturity groups. The hybrids were sown under different irrigation modes (common sprinkling, drip irrigation, sub-irrigation) and without irrigation to compare their drought resistance. The characteristics of the interaction genotype–environment, differentiation of the varieties by productivity and stability were realized by the method of Eberhart S.A. and Russell W.A. The coefficient of ecological plasticity bi and the variance of stability S2di were determined. The coefficient of drought resistance was determined by the correlation of productivity without irrigation and irrigation conditions. The methods used in the research are field, lamoratory, statistical and retrospective.
