| 摘 要： | 对＂十一五＂通过四川省审定的50个中籼迟熟三系杂交稻组合的产量和稻瘟病抗性进行了分析,并研究了产量与稻瘟病抗性的相关关系。结果表明,50个杂交稻组合中丰抗结合较好的组合有1个;丰产性突出、感稻瘟的组合有7个;抗稻瘟病的组合有1个。区域试验产量与颈瘟平均级呈极显著正相关,与颈瘟最高级呈负相关;颈瘟鉴定的平均级与叶瘟的最高级和平均级呈极显著正相关。该试验为水稻生产的发展提出区域优势品种布局建议,并为培育超高产、抗稻瘟病能力强的强势组合提供参考。

| Abstract: | Fifty combinations of middle-indica ternary hybrid rice with late maturity approved in Sichuan during the 11th Five-year Plan were analyzed for yield and rice blast resistance and the correlation between yield and rice blast was studied.The results indicated that there was one combination with good yield and resistance,seven combinations had outstanding yield but were susceptible to rice blast and one combination with resistance to rice blast.The yield in regional test showed extremely significant relation ... |
