Genetic variation and Rht gene distribution across a century of breeding in North American spring wheat.

Abstract excerpt

Hard red spring wheat (HRSW) is an important market class of wheat in North America. We genotyped 1013 HRSW lines representing a century of breeding using single-nucleotide polymorphism (SNP) array and targeted Kompetitive Allele-Specific PCR (KASP) genotyping to assess changes in genetic diversity and Rht genes. Our results suggest that early breeding efforts broadened an initially narrow gene pool derived from...
