早籼稻因其耐储藏、商品率高等特点,是我国也是浙江省粮食安全的重要支撑。本文分析了2003—2020年参加浙江省早稻区试品系的特征特性和变化情况,浙江省早稻种植面积、单产和总产的变化情况,浙江省代表性早稻品种在全国的推广应用情况,及浙江省早稻生产趋势,为进一步培育优异早稻品种、发展早稻生产提供参考。

Because of its characters of long-term storage and high commodity rates, early-season rice is an important support for food security in China, as well as in Zhejiang Province. Therefore, characteristics and trends of whole growth duration, yield and disease resistance were analyzed for the lines participating in the regional trials of early-season rice in Zhejiang Province in the past 18 years（2003—2020）. The changes of planting area, yield per mu, total yield of the early-season rice and application of representative varieties were further dissected in Zhejiang Province. The trend of early-season rice production in Zhejiang Province was discussed and concluded, to further provide reference for breeding elite rice varieties and dvevloping early-season rice production.
