ABSTRACT
During 1994 and 1995, 273 native buffalograss accessions were collected across a 480000 km2 area of the Lower Great Plains. In the tall of 1995 and the spring of 1996, these accessions and seven cultivars were evaluated for fall dormancy and spring green-up at Lubbock, TX. Significant differences between accessions were observed at all four evaluation dates for the onset of fall dormancy and for the initiation of spring greenup. Nine accessions were identified for delayed onset of fall dormancy and five accessions were selected for early spring green-up that could extend the growing season of buffalo-grass.
