Discriminant analysis use for validation of genetic distance between the samples of rice in case of a pair selection for hybridization

Abstract

The varieties of a domestic breeding were studied against the four backgrounds of an inorganic nutrition for the analysis of the variability of 24 attributes. When discriminant analysis uses, the experience tab, which provides a wide variation of the trait, makes it possible to validate more reliably the genetic distance between the samples and evaluate not only morphological traits, but also the variety's response to changes in the environment. As a result of the study, the combinations with the maximum distance between the parental forms are distinguished, which are characterized by an increased probability of heterosis in a number of ways.
