摘要
以新一代杂交黄瓜品种华黄2号为材料,研究了总产量与其他12个性状的相关性和通径系数。相关分析结果表明,采瓜数、平均单瓜重、坐果率、早期产量等性状与总产量呈显著正相关,早期产量与早期采瓜数等性状呈显著正相关;第1朵雌花节位与总产量呈极显著负相关。通径分析表明,总产量主要受采瓜数与平均单瓜重直接影响。
Correlation analysis and path analysis were carried out in cucumber huahuang No. 2 for their performance of yield and other 12 characters. The result of correlation analysis revealed that number of fruits per plant,average fruit weight, fruiting rate and early yield were related to the yield positively. Significant positive correlation existed between total yield and early fruit number and fruiting rate. Significant negative correlation existed between total yield and node of first female flower. The results on path analysis showed that the yield was affected mostly by two agronomic characters, the number of fruits per plant and average fruit weight,and was indirectly affected by fruiting rate.
