Selection on many mealies as one of methods to increase the productivity of corn

In article results of estimations the general and specific combinational ability and genetic estimation of parameters the quantitative attributes of new and perspective for Kabardino-Balkariya many mealies lines of corn received at participation of chemical mutagens are brought. It is shown, that the majority of lines possess high general combinational ability. In genetic control of an attribute "the number of mealies" at the studied lines is established incomplete domination. In the genetic control of attributes "productivity of grain" and "the number of grains from a plant" at lines is established overdominance and symmetry in distribution prepotent and recessive alleles.
