A new tea variety named "Ooiwase" is a clone suitable for green tea. It was bred by the Cultivation Laboratory of Shizuoka Tea Experiment Station and was adopted as a recommended variety of Shizuoka prefecture in February, 1977. "Ooiwase" originated from the F, hybrid of "Yaeho" (the superior early variety) ×"Yabukita" (the superior medium variety).<BR>"Ooiwase" is a early variety with a intermediate growth habit and numerous shoots. The sprouting time of this variety is about ten days earlier, and the plucking time is about five days earlier than those of "Yabukita", respectively.<BR>The superior characteristics of this variety are vigorous growth, high yield and fine quality. The yield is greater than that of "Yabukita", and its quality is as good as that of the "Yabukita" and it is the best among early varieties and clones. Cuttings of this variety root readily and show good growth after rooting and planting.<BR>The warm areas of Tokai, Kinki and Kyushu regions are adapted to cultivation of this variety. As "Ooiwase" is a early variety, the cultivation is recommended in the warm areas where the tea plant rarely suffers from frost injury or in frostless zones.<BR>One case of the varieties combination for the rational management of the tea industry is as follows ; a early variety "Ooiwase"-a medium variety "Yabukita" - a slightly late variety "Kanayamidori"- a late variety "Okumidori".
