Comparison of [S.sub.1] with open-pollination progenies in selection for yield in crested wheatgrass.(Crop Breeding, Genetics & Cytology)

From: Crop Science | Date: May 1, 2004| Author: | Copyright information

Genetic gain from selection for high dry matter yield in most cross-pollinated forage grasses has been an elusive goal, in spite of sustained breeding efforts. This study was conducted to determine the value of one generation of self-pollinating ([S.sub.1]) before selection for yield in crested wheatgrass (Agropyron spp.). Dry matter yields were compared at two locations near Mandan, ND, for synthetic populations derived from selection among and within [S.sub.1] of among and within open-pollination (OP) progenies from three source populations. Within each source population, the 20 parents ...
