Chromosomal Location of a Wheat Osmoregulation Gene Using RFLP Analysis

Abstract

The chromosomal location of an osmoregulation gene locus (or) was examined by exploring genetic linkage to restriction fragment length polymorphism (RFLP) loci which have been mapped on group 7 chromosomes or located specifically on chromosome 7A. The osmoregulation gene had previously been located on chromosome 7A, but its specific position was unknown. Analysis of linkage with the RFLP loci suggested a probable position on the short arm approximately 13 cM towards the centromere from RFLP locus Xpsr119. The findings, which were based on a relatively small sample, are of a preliminary nature and require confirmation with a larger set of genetic stocks.
