Genetic Analysis of Rice Appearance Traits in Indica Rice

This paper discussed brown rice traits by the genetic analysis on heritability, geneticadvance and genetic correlation, and suitable selection methods for good cultivars. The resultsindicated that chalkiness index was controlled by polygenes, its heritbility was higher than othersand stabilized early, so strictly selection should be done in early generation. The slightly negtivecorrelation existed between. grain Iengthand and 100 - grain weight. There were significantnegative relationship among grain length, grain width and grain thickness. The positivecorrelation existed among grain weight, grain width and grain thickness.
