摘　　要：以16个番茄自交系为材料,对番茄果实中番茄红素含量与7个农艺性状的遗传相关性研究结果表明,番茄红素含量与节间长度、始花节位存在极显著的负相关,与株幅、花序间叶数显著负相关;序间叶数、节间长度对番茄红素含量的直接通径系数和遗传相关系数方向相同,均为负值。Correlation and path analysis between lycopene content and other 7 agronomic characters of tomato was carried out by using 16 self-crossed lines.The results showed that there is very significant negative correlation between node length of inflorescences,first florescence node and lycopene content,and significant negative correlation between plant width,leaves between inflorescence and lycopene content,the direction of correlation coefficients and direct path coefficients of node length of inflorescences and leaves between inflorescences to lycopene content are the same.
