| 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F_1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 Wanpin 28 were related,and its high-and-stable-yielding ability was analysed. Wanpin 28 has following advantages; 1. Ideal plant type; 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 adaptability to unfavourable circumstances; 5.Good grain quality. Its yield is high and stable, generally, the grain yield is 550-600kg/mu, and the maximum comes up to 750-800kg/mw. 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. |
