Genetic control system of the differences in duration of vernalization in winter common wheat
[Free Full Text (pdf)]
Hypotheses of differences in genetic control on duration of vernalization for winter wheat have been considered. It has been shown that differences in this character are controlled by independent Vrd gene system. Monogenic dominant near-isogenic lines have been created. They differ in two non-allelic Vrd1 and Vrd2 genes with unequal expression. The response of created lines to photoperiodic changes and Vrd genes effects on various agronomic traits have been characterized. Vrd genotypes have been identified in a number of winter common wheat cultivars.
