EVALUATION OF LcyE AND CrtRB1 GENE POLYMORPHISMS ASSOCIATED WITH AN INCREASED CONTENT OF PROVITAMIN A IN MAIZE GRAIN (ZEA MAYS L.) IN THE COLLECTION OF SAMPLES OF DIFFERENT ECO-GEOGRAPHICAL ORIGIN
Abstract
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.
