Генетические корреляции признака толщина соломины второго междоузлия у сортов и линий пшеницы озимой

Abstract

The studying of genetic correlations between character ―culm thick- ness of second internode‖ (CT-2I) and some quantitative characters of gener- ative and vegetative parts of winter wheat. It was establish that correlations of CT-2I with grain weight per ear are stable high by sowing terms and investi- gation years. The general tendency of correlation decrease of CT-2I with several generative and vegetative characters in late sowing terms was noted. The selection of winter wheat lines on early stages of breeding can be im- proved by using data from genetic correlations
