Abstract
Manila grass (also South Japanese grass; Zoysia matrella L.) usually completely withers at the leaf part in winter in an area where frost occurs. The present variety of Manila grass is characterized by the ability to maintain green leaves (evergreen) in a whole year, a trait which has not been observed in other Manila grass varieties. The general characteristics of the present variety include somewhat straight grasses, slender leaf blades, and vividly green leaves, as well as dense greens which can be maintained in all seasons. The variety is somewhat resistant to turfgrass rust disease and is also resistant to usual pests, thereby reducing the cost of pesticides. In addition, the frequency of sprinkling, fertilization, and trimming can be reduced, so that labor can be saved in cultivating the variety.
