The results of analysis of the genome formation in interspecific hybrids of Triticum aestivum with T. timopheevii are reviewed. The spectra of substitutions and rearrangements are shown to depend on the genotypes of the parental forms and on the direction of selection. The frequencies of substitutions of individual T. timopheevii chromosomes significantly(More)
The karyotypes of 47 hybrid lines obtained from crosses of common wheat Triticum aestivum L. (cv. Rodina and line 353) with Triticum timopheevii(Zhuk.) Zhuk. (A t A t GG) and related species T. militinae Zhuk. et Migusch. (A t A t GG) and T. kiharae Dorof. et Migusch. (A t A t GGD sq D sq) were analyzed by C-banding. Most lines were resistant to yellow rust(More)
Hybrid necrosis genotypes have been identified in 125 Russian cultivars of winter bread wheat. More than half of them (56%) carry the Ne2 gene (genotype ne1ne1Ne2Ne2); others are free of necrosis genes (genotype ne1ne1ne2ne2). The possible causes of the increase in the Ne2 allele frequency and the loss of the Ne1Ne1ne2ne2 genotype in modern Russian(More)
Ninety-four lines of Triticum dicoccum isolated from 86 wheat accessions from Vavilov All-Russia Research Institute of Plant Industry (VIR, Russia) and INRA (Clermont-Ferrand, France) germ-plasm collections were studied using C-banding technique. Visual comparison of karyotypes of different accessions was performed to establish genetic relationships and(More)
Study of necrosis genotypes of 72 Russian cultivars of winter common wheat has confirmed a tendency towards “washing off“ of genotypes with the Ne1 gene. Fifty-six percent of cultivars have the genotype ne1ne1Ne2Ne2, and 44% have the genotype ne1ne1ne2ne2; i.e., they are free of hybrid necrosis genes. The results of the study indicate that the diversity of(More)
The distribution of hybrid necrosis genes in aboriginal wheats of Middle Asia (Tadzhikistan, Kyrghyzstan, Uzbekistan, and Turkmenistan) was studied. Necrotic genotypes were identified in 154 samples including 147 samples of Triticum aestivum, six samples of T. compactum, and one T. antiquorum sample. The absence of the Ne2 gene in this region was shown.(More)
