Diversity and Phenotypical Effect of Allelic Variants of Rht Dwarfing Genes in Wheat

The review is devoted to the description of allelic variants of Rht genes and their effect on the traits associated with the growth, development, and yield of wheat plants. The effect of Rht genes on the growth and development of wheat plants through DELLA proteins is considered. A new classification of wheat plants by the height (stem length) based on the presence/absence of strictly defined alleles of Rht genes determined by molecular genetic methods in their genotypes is proposed.
