ABOUT OPTIMIZATION OF MOLECULAR LABELING OF WHEAT Waxy-GENES FOR MAS-SELECTION
M.V. Klimushina, P.Yu. Kroupin, M.G. Divashuk, G.I. Karlov
The results of the investigations show that the two molecular markers for Wx-A1 and Wx-B1 loci can be recommended for marker-assisted selection of wheat. They have been found to be suitable both for searching for the null-alleles among the variety of Russian cultivars and for MAS-selection for reduction of amylase content in grain. Using the selected markers the authors have developed the wheat lines containing two null-alleles of Wx-genes, which can be applied as donors to transfer these alleles to other wheat cultivars.
Key words: marker-assisted selection, molecular markers, Waxy-genes, bread wheat.
