| 摘 要： | 本文对糙米性状进行了遗传力、遗传进度和遗传相关系数分析，提出了适宜的选择方法．结果表明：垩白指数受多基因控制，遗传力较高（82．03％），稳定旱，应在早代加以严格选择．粒认与百粒重存在微弱的负相关．粒长与粒宽、粒厚负相关显著．收重与拉宽、粒厚有极显著正相关．

| Abstract: | 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. |
