Проведена оценка ключевых полиморфизмов генов LcyE и CrtRB1, ассоциированных с повышенным уровнем провитамина А в зерне кукурузы (LcyE 5′TE, LcyE 3′Indel и CrtRB1 3′TE), в коллекции из 54 образцов различного эколого-географического происхождения. В изученном материале не выявлено присутствия благоприятных аллелей гена LcyE. Выделены генотипы (35 % образцов), несущие благоприятный аллель 1 функционального маркера СrtRB1 3′TE, которые представляют интерес для селекционных программ кукурузы, направленных на повышение качества зерна.

The collection of 54 maize samples of different eco-geographical origin was evaluated for the key polymorphisms of the LcyE and CrtRB1 genes (LcyE 5′TE, LcyE 3′Indel and CrtRB1 3′TE) associated with the provitamin A content in maize grain. Favorable alleles of LcyE were not detected in the studied material. Selected genotypes with favorable allele 1 of СrtRB1 3′TE functional marker (35 % of the samples) are of interest for maize breeding programs aimed at improving the grain quality.
