50年代以来,我省种植的早稻品种达500多个,种植品种从高秆到矮秆、农家品种到引进育成品种、单一熟期到早、中、迟熟搭配,产量稳步提高。但近10年来,早稻品种出现多、乱、杂,当家品种不突出,产量徘徊不前。本文通过对我省38年早稻品种演变的回顾,揭示品种与产量的关系,分析探讨当前品种应用存在的问题,提出今后早稻品种选育与推广的发展方向
Since the 1950s, more than 500 varieties of early-season rice have been planted in our province. The cultivars have grown from tall stalks to short stalks and farmers’ varieties have been introduced into bred varieties. The yield has been steadily increased from a single ripening stage to early, middle and late ripening. However, over the past 10 years, early varieties of rice appeared more, chaos, miscellaneous, when the species is not prominent, output stagnated. Based on the review of the evolution of 38-year-old rice varieties in our province, this paper reveals the relationship between varieties and yield, analyzes and discusses the problems existing in the application of current varieties, and points out the development direction of future breeding and promotion of early-rice varieties
