线辣椒主要农艺性状相关性分析及产量因素通径分析

试验对20份线辣椒材料主要农艺性状进行了相关性分析,并对产量因素进行了通径分析。结果表明：线辣椒始花节位、叶长和叶宽与全生育期呈极显著正相关;果横径、单果果肉重、平均单果重与单株结果数之间存在显著负相关;而果横径与单果果肉重、平均单果重呈极显著正相关;株高与单株结果数、叶长、叶宽呈极显著正相关;线辣椒单株产量对总产量的贡献最大,并呈极显著正相关,平均单果重和单株结果数对总产量存在一定的正向影响,果横径对总产量有负向影响,果纵径对总产量影响不明显。

Correlation Analysis on Main Agronomic Traits and Path Analysis on Yield Components of Chili Pepper

The tested data derived from 20 different chili pepper materials were conducted to analyse the correlation of main agronomic traits of tors. The results showed that node of the positive correlation with total growth peri weight had a significantly negative correlat chili pepper and conducted the path analysis of its yield facfirst flower, leaf length and leaf width had a significantly od; fruit width, flesh weight of single fruit and per fruit ion with fruit number per plant; but fruit width had a significantly positive correlation with flesh weight of single fruit and per fruit weight; plant height had a significantly positive correlation with fruit number per plant, leaf length and leaf width; Single plant yield had the most important contribution to total yields, and it had a significantly positive correlation with total yields, per fruit weight and fruit number per plant improved the total yields, fruit width decreased the total yields, and fruit length had no obvious effect to total yields.
