本文报道咖啡产量指数选择效率的研究结果,这些结果是将植株头2、3年各种形态特征和产量与生产10年后产量的直接选择进行比较选择取得的。本研究是在肯尼亚品种试验估算出的小粒种咖啡若干数量性状的表型、基因型方差和协方差基础上进行的。
This paper reports the results of the study on the efficiency of coffee yield index selection. These results are obtained by comparing the first two or three years of plant head morphological characteristics and yield with the direct selection of the yield after 10 years of production. This study was conducted on the basis of the phenotypic, genotypic variance and covariance of several quantitative traits of small-grain coffee estimated by the Kenya breed test.
