摘要： 1979～1987年,以朝鲜地一号（粳）为母本,印度杰雅（籼）为父本杂交后,用其F₁与垦77-9复交,经6代培育成晚品-28水稻新品种。该品种具有株型好、产量三要素搭配合理、抽穗早灌浆期相对长、抗逆性强、适应性广、品质佳等优良经济性状。产量高而稳,一般亩产550～600kg,高产地块达750～800kg,比当地主栽品种增产10～15％。目前已在河北省大面积种植,在天津、北京和山东等省市大面试种成功。

Abstract: The breeding procedure and the key culture technics for the new variety W anpin 28 were related,and its high-and-stable-yielding ability was analysed.Wanpin 28 has following advantages; 1.Ideal plant types 2,Optimum allocation of three elements for high yield (panicle number per mu, filled grain number per panicle and 1000-grain Wight;3,Earlier heading date and longer filling period; 4,Higher adverse resistance and better adap tability to unfavourable circumstances， 5,Good grain quality, Its yield is high and stable, generally, the grain yield is 550-600kg加u, and the maximum comes up to 750-800kg/mu, The yield is higher by 10-15} than that of other local varieties, Now the variety has been popularized in large areas in Hebei province and cultivated successfully in Beijing, Tianjin and Shandong province.
