ABSTRACT:

Bermudagrass (
Cynodon dactylon
(L.)) ‘P-18’ is a new and distinct cultivar of turfgrass which is developed for golf greens, tees, fairways, athletic fields and home lawn grass.
BACKGROUND
An important characteristic of a good turfgrass is density. Maintaining good density at very low heights is particularly vital when used one golf course greens which are typically maintained at a height of {fraction (1/18)} inch. At this height, density is critical to avoid sunlight from reaching the surface of the soil. When this happens, weed invasion becomes more a problem but most greens receive a daily irrigation which allows algae to begin to grow on the soil. Algae causes the turf to lose even more density creating thinning or even bare spots on the greens.
In order to accommodate the low mowing heights on a putting green, it is desirable to have a variety which exhibits a fine leaf texture and a vertical leaf orientation. Due to frequent mowing, leaves which grow vertical are beneficial in providing a flat surface for golfing.
Turfgrass varieties selected for putting greens must have quality characteristics of: 1) density; 2) low, creeping growth habit; 3) tolerance to close mowing; 4) fine leaf texture; 5) excellent reproduction rate; and 6) good uniform color.
SUMMARY OF THE INVENTION
This invention relates to a new and distinct Bermudagrass (
Cynodon dactylon
) designated P-18 which is outstanding because of its 1) extremely fine leaves; 2) its improved density; 3) its rapid growth rate; and 4) its uniform green color. The claimed Bermudagrass P18 was primarily selected for these characteristics. This selection was made from a breeding program designed to develop improved varieties of seed producing Bermudagrass in Yuma, Ariz.
ORGIN AND ASEXUAL REPRODUCTION
Asexual reproduction of this turfgrass by vegetative propagation was directed by me, such reproduction establishing that the plant does in fact maintain the characteristics described, in successive generations. ‘P-18’ was first produced in 1992 and is a mutant obtained from a Bermuda line believed to be TifDwarf Bermuda grass which was grown in a greenhouse owned by H&H Seed Company in Yuma, Ariz. ‘P-18’ was selected and evaluated for traits and characteristics as described in the patent application. ‘P-18’ has been asexually reproduced for several generations and the traits have been stable.
