1.前言从最近日本苹果品种发展的动向来看,原产量高的元帅系减少,早熟品种“津轻”和晚熟品种“富士”成为主栽品种。尤其是“富士”苹果已占日本苹果总产量的50%以上。正值人们期待早、晚熟之间品种出现之际,“千秋”苹果作为中熟品种于1980年在秋田县进行了种苗登记。
1. Introduction From recent trends in the development of apple varieties in Japan, the high yield of the mandarin is reduced, early maturing varieties “Tsugaru ” and late-maturing varieties “Fuji ” become the main cultivars. In particular, “Fuji” Apple has accounted for more than 50% of Japan’s total apple production. At a time when varieties are expected to appear between early and late ripening, “Chiaki” apple was registered as medium maturing seed in Akita Prefecture in 1980.
