Stability of yield and yield components of rice and correlation analysis of high-yield related characters
摘要
Abstract
In order to provide scientific basis for validation and application of rice varieties in arid and semi-arid ar-eas ,6 rice varieties (lines ) was planted in 6 different ecological sites in Heilongjiang Province to analyzed the stability of yield and yield components (spike per hole ,grains per spike ,1000-grain weight ,and seed setting rate ) of rice by using AMMI model .The results showed that the interaction of genotype and environment (G × E) affected significantly on yield and yield components of rice .Under the condition of various rice varieties (lines ) planted in different regions ,the stabil-ity of yield and yield components was much different ,in which the yield of Kendao 08-924 was the most stable .850 Farm and Junchuan Farm were suitable for regional test of rice .The number of secondary rachis per spike and spike length were correlated with all characters at significant or extremely significant level , except for seed setting rate and yield .The rice yield was positively correlated with spike number at significant level ,but it was not significantly correlat-ed with other characters .关键词
