الروسية. Изучены два ДНК-маркера митохондриального гена cob, характеризующие S- и N-типы цитоплазмы, маркер митохондриального региона orfA501, выделяющий S- и T-стерильные типы цитоплазмы и два маркера, косегрегирующие с Ms или ms, ядерными генами, контролирующими фертильность фенотипов с S-цитоплазмой, лука репчатого (Allium cepa L.) на примере сортов белорусской селекции.
اظهر المزيد [+] اقل [-]إنجليزي. The article analyzes two DNA-markers of mitochondrial gene cob characterizing S- and N-cytoplasm, marker of mitochondrial region orfA501 with S- and T-cytoplasm, and two markers co-segregating with Ms or ms, nuclear genes which control the fertility of phenotypes with S-cytoplasm in the onion (Allium cepa L.) varieties developed in the Institute of Vegetable Growing. For the research 2 onion varieties of belarusian selection have been used. Evaluation of cobS marker of individual maternal onions of varieties Vetraz and Scarb has been made. Distribution of cytoplasm types and nuclear alleles of sterility fixing agents and reducing substances of individual plants of onion has been analyzed. Inflorescence seed number within difficiency of open pollination has been calculated. Polymorphism of anthers of onion maternal plants of different genotypes has been analyzed. Analysis of fertility of hybrid combinations of seed plants has been made. Comprehensive evaluation of polimorphism of different onion varieties has been carried out. Сompatibility of alleles has been analyzed.
