粳糯产量与产量构成因素的灰色关联度分析
Grey Correlation Degree Analysis of Glutinous Geng Rice Yield and Yield Components
摘要
Abstract
In order to ascertain the influence of yield components on glutinous geng rice yield,grey correlation degree analysis was used to comprehensively evaluate the 11 yield-related characters of 15 glutinous rice germplasms.The results showed that grey correlation degree between yield components and yield in descending order were effective panicle＞seed setting rate＞filled grain number＞total grain number＞plant height＞thousand-grain weight＞growth period＞flag leaf width＞panicle length＞flag leaf length,and their correlation degree values were 0.785 6,0.738 2,0.723 8,0.710 5,0.708 9,0.675 2,0.673 7,0.667 5,0.661 3 and 0.655 5,respectively.Comprehensive analysis of grey correlation degree indicated that breeding of high-yield glutinous rice should focus on the selection of effective panicle,seed setting rate,filled grain number and total grain number.关键词
