ybridized combinations were designed using ‘Song 93-8’ as parent, and pedigree method was adopted to choose the future generations in order to verify ‘Song 93-8’ was high quality rice core germplasm resources. The results show that 23 new rice species were bred in 11 years. And the species bred had such characteristics as early maturity, superior quality, high yield and strong resistance, and were cultivated with the cumulative promotion area 2013000 hm2. Growth period and plant height, spike length, yield presented significant positive correlation, and presented extremely significant negative correlation with rice blast. Head Rice Ratio presented extremely significant positive correlation with brown rice percentage and chalkiness ratio. It was positive correlation between taste value and brown rice ration, head rice ratio, gel consistency, and negative correlation with chalkiness ratio, chalkiness degree, amylose content. So ‘Song 93-8’ had strong heritability and combining ability, was high quality rice core germplasm resources with a broad genetic base.
