摘　　要：为揭示辣椒各农艺性状间的相关关系,为良种选育时对各性状的选择及辣椒高产优质栽培提供理论参考,对国外引进的202份辣椒材料的主要农艺性状及其相关性进行调查分析,结果表明,株高和果形呈极显著正相关,与果肉厚、维生素C(Vc)含量、平均单果质量呈显著负相关;果形与果肉厚、Vc含量呈显著负相关,与胎座大小呈显著正相关;胎座大小与Vc含量呈显著负相关;平均单果质量除了与果肉厚呈极显著正相关外,还与果宽呈显著正相关,说明辣椒单果越粗,单果质量越大。选择高产辣椒时,可以选择叶片较大、果较宽偏向于灯笼形的株系配组,以提高单果质量;若以辣椒果实中高Vc含量为育种目标,应注重小株型厚果肉品种的选育。The main agronomic traits of 202 foreign pepper materials were investigated, and the correlationships among the main agronomic traits were analyzed. The results showed that plant height was significantly positively correlated with fruit shape, significantly negatively correlated with thick of flesh, Vc content and average weight of single fruit; fruit shape was significantly negatively correlated with thick of flesh and Vc content, significantly positively correlated with placenta size; placenta size was significantly negatively correlated with Vc content; average weight of single fruit was significantly positively correlated with thick of flesh thick flesh and fruit width, indicating that the wider fruit was, the more single fruit weight was. In high-yield pepper breeding, smaller leaves line can hybridize wider lantern-shaped fruit line, so as to improve single fruit weight;In order to breeding pepper with high Vc content, the variety which plant type is small and flesh is thick should be breeded.
