A new tea variety named "Kanayamidori" is a clone suitable for green tea. It was bred by the Breeding Laboratory of Tea Agronomy Division, Tea Research Station, and registered with M. A. F. as a superior variety in April, 1970. "Kanayamidori" originated from the F1 hybrid of S6 (the Shizuoka native variety) × "Yabukita" (the superior green tea variety). Both mature and young leaves of this variety are smaller in size than those of "Yabukita", slightly elliptic in shape, glossy, and dark green in colour. "Kanayamidori" is a slightly late variety with a spreading growth habit and numerous shoots. The sprouting time of this variety is about eight days later, and the plucking time is about four days later than those of "Yabukita", respectively. The superior characteristics of this variety are strong cold-resistance, vigorous growth, high yield, and fine quality. Its yield is much greater than that of "Yabukita", and its quality is as good as that of the latter. Cuttings of this variety root readily and show good growth after rooting. "Kanayamidori" is adapted to the green tea areas of Tokai, Kinki and Kyushu regions, and also some hilly areas because of its tolerance to cold and its late plucking period.
