A century of breeding has preserved genetic variation, accumulated favorable alleles, and shaped the Rht gene portfolio in North American spring wheat

This study analyzes genetic diversity and Rht gene changes in North American spring wheat over a century, showing shifts in allele frequencies and their impact on plant height.

Genetic Gains from Sixty Years of Spring Wheat Breeding in the Northern Plains of the US

This study quantifies genetic gains in HRS wheat over 60 years, finding annual yield gains of 0.61% but no improvement in grain protein since 1995.
