title: Differences in the alternate varieties of soft wheat for Vrn-1 genes of development type
abstract: Purpose. To study the response to vernalization and to identify Vrn-1 genotypes of modern alternate soft wheat varieties of various origins. Methods. Temporal vernali­zation, hybridological analysis of the development type according to the Vrn-1 gene system, dispersion and correlation analyses, criterion c2 for assessing the correspondence of the actual splitting results to the theoretical hypothesis. Results. Alternate varieties vary considerably in the length of the period before earing under
