| 摘 要： | 为明确不同生态条件下各水稻品种的产量性状差异,通过比较169个水稻品种(系)2009年正季在哈尔滨和冬季在海南三亚种植的生育期和产量性状,结果表明:5种不同抽穗期类型的水稻品种(系)在三亚冬季种植条件下比哈尔滨正季种植抽穗期均缩短,且两地的差异达到极显著水平。同时各供试品种(系)在哈尔滨和三亚不同的生态条件下单株有效穗数、每穗实粒数、结实率和千粒重等各性状均有所变化,但品种间有所不同。因此在北种南繁时,应根据材料特性和当地气候条件采取相应的措施。在南繁选种时,应注意品种间各性状的差异,根据品种特性选择优良单株。

| Abstract: | The 169 rice germplasm(Oryza sativa.L)were grown in Harbin city and Sanya city in 2009 and 2010 year to understand the difference of yield traits under two different ecological conditions.The variance of growth period and yield traits were analyzed.The result showed that the heading stage of five different heading stage types was significantly shorter in Sanya than that in Harbin,and the difference reach remarkable significant.The traits of varieties(lines)were different in Harbin and Sanya,such as tillers per plant,grains per panicle,seed setting rate,1 000-grain weight.When northern varieties planted in south,should take the appropriate action according to the variety characters and local whether condition.The differences of various characteristics between varieties should be paid attention to and excellent plant should be selected according to variety characteristics in the breeding process in South. |
