| 摘 要： | 对有棱丝瓜10个品种的10个主要农艺性状进行了相关及通径分析。相关分析表明。瓜长、单瓜质量等2个性状与产量呈极显著正相关，前期产量、瓜形指数与产量呈显著正相关，始收期与产量呈极显著负相关，第一坐瓜节位与产量呈显著负相关；通径分析表明，结果数和单瓜质量2个性状对产量形成的直接作用最大。且对产量的决定系数总和达0．9812。因此，可以作为有棱丝瓜高产育种的主要选择性状。

| Abstract: | Correlation and path analysis of 10 agronomic characters were studied with 10 cultivars of sponge gourd( Luffa acutangula Roxb.).The results of correlation analysis revealed that very significant positive correlation were found between the fruit length,fruit weight and yield, and significant positive correlation were found between yield of earlier stage,fruit index and yield.While, very significant negative correlation was found between days of first harvester and yield ,and significant negative correlation was found between nodes of first fruit and yield; The results on path analysis showed that the yield was affected mostly by two agronomic traits, the number of fruits and average fruit weight by turn. |
