Abstract
Agronomic characters of core germplasm Luzhenzhan 8 and its pedigree grown in late-cropping season were evaluated and quality indices were tested systematically. Correlation analysis showed that yield was significantly positive correlation to seed setting rate, panicle length, flag leaf length and 2~(nd) leaf width and 3~(rd) leaf width; but significantly negative correlation to length of 2~(nd) and 3~(rd) leaf. Eating quality was significantly negative correlation to chalky grain and chalkiness and highly positive correlation to gel consistency. Principal component analysis indicated that panicle length factor had very significantly positive linear relationship to yield. Head rice factor had very significantly negative linear relationship to eating quality. Based on these studies, a ideal plant type for breeding of South-China late-cropping quality rice was constructed.
