Molecular markers were used for screening of the onion plants of VNIISSOK's breeding for cytoplasmic male sterility. Allelic variations of the mitochondrial genes orfА501 and cob were reveled among studied onion samples. Use of the PCR-markers for these genes allowed identifying the cytoplasmic types of 14 onion genotypes. Application of these molecular markers in breeding program could help to select genotypes wit certain type of cytoplasm and may be useful for high throughput identification of cytoplasmic male sterile factors in large onion breeding populations.

Селекционная, д. 14 Тел. 8 (495)599 24 42, факс 8(495) 599 22 77 E mail: vniissok@mail.ru В статье представлены результаты изучения наследования окраски сухих чешуй лу ковицы лука репчатого. Показано, что различия по окраске луковиц (желтые, корич невые, белые, красные и другие окраски) обусловлены отличиями в генотипе растений от одного до трех генов.Ключевые слова: лук репчатый, расщепление инбредных (I 1 I 2 ) и гибридных потомств (F 1 , BC 1 ) по окраске луковиц, гены и генотипы окрасок.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
