Description

The object of the study is the genetics of millet, the technological qualities of grain, the source of economic and valuable features. The purpose of the work is to study the peculiarities of genetic control of the characteristics of the technological qualities of millet grain (size, fillet, grain form) for the creation of genetic sources of high mass of 1000 grains, optimum filamentary and spherical form of grains in combination with other economic and valuable features. Stage - Determination of features of inheritance of test characteristics in hybrid populations of F2 by hybridological analysis of individual plants. Methods of research - field experiments with artificial crossings, laboratory for determining the technological qualities of grain; Statistical analysis of the results of the research. The main results of the study were obtained from hybrids of the second generation of three populations in total 232 plants for determining the technological qualities of their grains (1000 grains mass, filamentary and grain form) in order to study the features of the inheritance of these traits. In the second generation, the weight of grains was inherited predominantly by the intermediate type (48-64%), as well as positive (17-42%) and negative (10-27%) super-domination were observed; the sign "mass of 1000 grains" is controlled by an additive-dominant gene system. The softness of grains of millet in second generation hybrids was inherited mainly by the intermediate type (57-82%), and also observed as positive (low-film - 4-13%) and negative super-domination (coarse-grained - 10-38%). The splitting on the basis of the grain form in the second generation hybrids occurred in a ratio of 9 spherical to 7 oval, indicating the complementary interaction of dominant alleles of the two independent genes controlling this trait.
