Analysis and Appraisal on Quality Traits of Indica Hybrid Rice in Fujian

CHI Xiao-wen(Seed Station of Fujian Province,Fuzhou 350003,China)  
According to the agriculture industry standard NY/T593-2002,eleven quality traits of milled rice of 282 indica hybrid rice varieties involved early-season,mid-season and late-season collected from Fujian regional test of cultivars from 2003 to 2005 were analyzed and appraised.The results showed that from 2003 to 2005,the three types of indica hybrid rice showed little difference in rate of brown rice,rate of milling rice,grain length,alkali value,gel constency,amylase content and protein content.While the significant dif- ference was detected in quality traits,such as percentage of head milled rice,percentage of chalky rice,de- gree of chalkiness and translucency.The coefficient variation of the corresponding traits showed the similar trend.The fine qualified rate of colligation appraisal only varied from 2.78% to 16.12%,especially early- season indica hybrid rice had the lowest value.Besides,the quality characteristics of high-quality hybrid rice and main strategy of rice breeding for high quality was proposed as the decrease in percentage of chalky rice and degree of chalkiness,the increase in percentage of head milled rice and simultaneous consideration to other quality traits indices.
