Correlation coefficients between rice resistance to blast and qualities of 131 varietieswhich were tested in the region trial in the cold region in recent 5 years. The result showed: A significant negative correlation effect between resistance to blast and grain Length/Width (L/W) ratio in cold region early japonica rice varieties; A significant positive correlation effect between resistance to leaf and neck blast and chalkiness factor included chalky grain, chalkiness and chalk size; A significant negative correlation effect between resistance to leaf blast and protein content. Leaf blast showed different relationship to steaming quality and eating quality in different experimental ways. A significant negative correlation effect to gel consistency(GC), amylose content (AC) and eating quality in artificial identification.
