Abstract/Contents:"Twenty seven St. Augustinegrass (Stenotaphrum secundatum [Walter] Kuntze) cultivars were planted in College Station, Texas on 15 August, 1996. No plots sustained extensive damage from cold weather in 1998, but Floratam suffered more winterkill than S 6-89 175, Winchester, MM 203, or S 80-47. There were no statistical differences between any genotypes in rate of spring greenup in 1998. For the year, NCSA 21, TX 8208, Floratam, S 6-89-194, S 6-89-174, and S 6-89-196 were rated lower in quality than the rest of the genotypes. S 6-89-156, S 6-89-194, CSR, S 89-14, S 6-89-175, S 6-89-174, FX 10, MM 1, and S 6-89-70 were rated in the top statistical group for turf density on all 3 rating dates and overall. The plots were rated for resistance to brownpatch (Rhizoctonia solani) and gray leaf spot (Pyricularia grisea) in late September. Ratings for most genotypes were statisticaly similar, except that Floratam sustained more damage from brownpatch than S 89-6-196, MM 203, TX 8208, Levi, S 89-6-174, and CSR. There were no significant differences between genotypes in gray leaf spot incidence in 1998."
