Abstract

Twenty selected Agropyron elongatum clones were evaluated in parent and progeny nurseries with each clone represented by 560 progenies. Agronomic characters evaluated on the progenies included degree of erectness, three height measurements, and green weight data. Correlations were calculated between the seed yields of the progenies and the forage yield of the parents. General combining ability was determined for the 20 clones.

The clonal source of variation for erectness was high. More variation existed within clones for green weight than for any other character studied. Two specific clones exhibited better over-all general combining ability than the others. Successive seed yields on the same nursery were highly correlated, whereas no correlation was found between progeny forage and parent seed yields.
