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.
