Dissection of rye chromosome 1R in common wheat.

Abstract

Rye chromosome 1R contains many agronomically useful genes. Physical dissection of chromosome 1R into segments would be useful in mapping 1R-specific DNA markers and in assembling DNA clones into contig maps. We applied the gametocidal system to produce rearranged 1R chromosomes of Imperial rye (1R(i)) added to common wheat. We identified rearranged 1R(i… (More)
