Technical Abstract: Flowering time in orchardgrass is critical for tolerance to abiotic stresses and forage quality. Most forage producers prefer late flowering orchardgrass whose flowering time matches that of alfalfa or clover. There are two genes in the constans (CO) gene family that respond to photoperiod and induce downstream flowering genes. We sequenced a large region of each of those genes in 48 diverse orchardgrass plants and determined the linkage and allele frequencies.
