摘要: 用单株穗数、主穗粒数、生长率、收获指数、生物学产量与籽粒产量的回归关系,分析了水稻的5个经济性状共26种组合。结果表明,只要有收获指数、生物学产量单独参与或共同参与组合的,回归就显著;没有这两个性状参与的就不显著,并且以生物学产量的 Up 最大。通径分析表明,生物学产量对籽粒产量的贡献最大,收获指数次之,生长率对

Abstract: Multiple regression relationships of grain yield of rice on the numberof panicles per plant,number of grains in the main panicle,growth rate,harvest index and biological yield were analysed in 26 combinations ofcharacters.The regressions were significant wherever harvest indexand/or biological yield
