Hereditability and recurrence of seed productivity determinants in summer russian turnip in the conditions of Tyumen' oblast'

摘要

The authors studied the reaction norm and degree of influence of different varieties of summer Russian turnip on seed productivity and stability of phenotypic diversity in connection with soil-climatic conditions. It was shown, that determinants of seed productivity in summer Russian turnip varieties depend to a great extent from genotypic heterogeneity of plants. The ecologo-genetic prerequisites for increasing the crop capacity of summer Russian turnip plants in the conditions of northern forest-steppe of Tyumen 'oblast' were discussed.
