Distribution of Hybrid Necrosis Genes in Genotypes of Winter Soft Wheat (Triticum aestivum L.) Cultivars of English Selection

The genetic diversity of 15 cultivars of winter soft wheat of English selection has been studied. It was found that 11 (73.3%) of the cultivars studied carried the Ne2 gene (genotype ne1ne1Ne2Ne2), and four cultivars (26.7%) were free of hybrid necrosis genes (genotype ne1ne1ne2ne2). The Ne1 gene was not detected. Cultivars with the Ne2 gene differed in allele strength. Moderate (Ne2^m) allele was identified in four cultivars, and moderately strong (Ne2^ms) allele was identified in the genotypes of seven cultivars.
