Abstract:The correlation analysis of Qingliuai No.1 and its pedigree showed that yield was highly significantly positive correlative to productive panicles and significantly negative correlative to spikelets panicle -1 , as well as filled grains panicle -1 ; The significantly positive correlation was also found between the length of the 3 rd top leaf and the length of the 2 nd top leaf, grain length, as well as gel consistency. Simultaneously , the length of the 3 rd top leaf was significantly negative correlative to spikelets density panicle -1 , chalky grain, chalkiness and amylose content. Principal component analysis indicated that plant height factor and spikelets factor had very significantly positive linear relationship to yield. The order of significance to yield was plant height factor>spikelets factor.The head rice factor had very significantly positive linear relationship to grain quality. It was proposed that attention should be paid for plant with more and longer panicles, less spikelets density panicle -1 , less spikelets panicle -1 as well as filled grains panicle -1 , a little taller plant height, longer and more transparent grain and bigger 1000 grain weight in selection for Qingliuai pedigree in Guangzhou. Other issues concerning further development of the pedigree were also discussed.
Keywords:Core germplasm  Pedigree  Character  Good quality rice  Principal component analysis
