Детермінація ознак продуктивності рослин, урожайності та адаптивна здатність гібридів цукрової кукурудзи

Abstract

In the northern Steppe of Ukraine there is studied variability, degree of association and adaptive ability sign witg individual productivity and grain yield of hybrids of the sugar corn. When shaping the productivities there is installed  the advantage of the sign "mass of the cob" in comparison with the cob number. The presence of compensation mechanism cob variable structures and grain yield determinates the low level genotype-environment dependencies of the present module of productivity. Plastic and homeostatic genotypes identification has a prospect of the use in the conditions of moisture provision and sloppy agrarian background, forming a  maximum and stable level of productivity of marketable products
