【摘要】 以籽用南瓜农家品种为供试材料 ,采用随机区组试验设计 ,用方差分析法估算了单株结瓜数、单瓜重、单瓜种子数和籽粒重的广义遗传力 .结果表明上述 4个产量性状的广义遗传力分别为 6 9 90 % ,90 73% ,96 6 5%和 80 0 0 % .本文还对籽用南瓜产量性状遗传力分析结果及其在育种中的应用进行了讨论更多还原

【Abstract】 Farm varieties of seed squash were used as experimental materials. The randomized block design and analysis of variance were adopted to estimate broad sense heritabilities of fruit number of single plant, weight of single fruit, seed number of single fruit and seed weight. Results showed that the broad sense heritabilities of fruit number of single plant , weight of single fruit, seed number of single fruit and seed weight were 69 90%, 90 73%, 96 65%and 80 00%. The results of heritability analysis and the utilization of heritability in crop breeding were discussed in this paper.更多还原
