Abstract

Abstract : 'NUF‐76' (Reg. No. CV‐276, PI 674513) St. Augustinegrass [ Stenotaphrum secundatum (Walt.) Kuntze] was developed from a series of complex crosses and is suitable for use as a turfgrass in lawns in the southern United States. It is resistant to southern chinch bug ( Blissus insularis Barber) biotypes in Florida and North Carolina, is the first diploid (2 n = 2 x = 18) cultivar possessing resistance to the most damaging insect pest of St. Augustinegrass, and is currently the only commercially available resistant St. Augustinegrass cultivar. It is also resistant to certain races of the fungal disease gray leaf spot, caused by Pyricularia grisea, and the planthopper ( Liburnia pseudoseminigra Muir & Gifford). NUF‐76 has short fine‐textured leaves relative to other St. Augustinegrasses. NUF‐76 has a significantly slower leaf extension rate compared with 'Floratam' and thus requires fewer mowings, reducing maintenance inputs. It produces a dense, high‐quality turfgrass that is similar to or better than Floratam which is the most widely used St. Augustinegrass for lawns in Florida and south Texas.
