Description
Summary:In the process of breeding work with the Pisum sativum culture, its manufacturability increases due to the introduction of new economically valuable features, as a result of the influence of abiotic factors on pea varieties is transformed. The work is relevant in timely identification of changes in influences and analysis of these transformations on the reconstructed genotype are important in breeding evolution. The material for the study was 12 samples of five varieties of Pisum sativum. The adaptability and stability indices of the samples - Indicator of the stability level of the variety, stability index, stress tolerance, breeding value, and the dependence of the adaptive properties of the culture on the complexity of its genotype were determined. The stress tolerance of the varieties was chaotic; its relationship with the evolution of the genotype is very weak. A strong positive relationship was revealed between the complication of the genotype and the coefficient of variation; a strong negative relationship was revealed between the resistance and stability index of the varieties. Strong negative dependencies were revealed between the evolution of culture and the stability index, as well as breeding value.
