摘要
以50个‘凤丹’单株为材料,对其生长及结实性状的变异进行了研究,结果表明:单株间‘凤丹’生长、结实性状间变异丰富,选择潜力大,分枝数、单株产量及荚果数为变异程度较高的指标;单株产量与荚果数间存在极显著的相关关系(r=0.776^(**)),荚果数可作为‘凤丹’产量的预测指标;以平均单株产量()加2倍标准差(2s)作为高产‘凤丹’的选择标准,入选率4%。
In this study,50 individuals of‘Fengdan'were selected and their growth and yield traits were analyzed. The results showed that there existed abundant morphological and yield diversity among‘Fengdan'individuals,and there was a significant positive correlation between yield and pod number( r = 0. 776-(**)),and pod number was useful for yield prediction. If the average yield per plant with two times of standard deviation was taken as its selection criteria for high yield‘Fengdan',its selected ratio was 4%.
