Heredity of Determination Coefficient in Cotton Plant Hybrids
Main Article Content
Abstract
The fiber yield and fiber length are strong, the weight of 1000 cottonseeds is average, and the weight of cotton boll in one piece is weakly determined. The weight of cotton in one cotton boll was recognized as ecological, the weight of 1000 seeds as biological, and the length of the fiber as genotypic indicator. The similarity of the first-generation hybrid with L-395 was 92.7%, and with L - 620-50.9%, according to the nature of inheritance of the degree and structure of correlations. This showed that the first-generation hybrid was similar to the L-39 range. When conducting breeding work in breeding, it is recommended to attach importance to the length of the fibers and the selection of genotypes, and to use the “correlation matrix comparison” method when comparing them.
