| 摘要: |
| 对辣椒的13个杂种一代及其16个亲本的总产量等16个性状进行分析,结果表明,辣椒的总产量与早期产量及果实胎座宽度呈显著正相关,与干物质含量呈显著负相关;单果重与胎座宽度及果肉厚度呈显著正相关,与单株果数呈显著负相关。株高与播种至花期天数,始花节位与播种至花期天数及维生素C含量与果实长度之间也呈显著正相关;单株果数对总产量的直接影响最大,果实胎座宽度及早期产量也对总产量有明显的直接影响,而其它性状则仅对总产量产生有限的直接影响。 |

| Abstract: |
| Phenotypic correlation analysis and path analysis were carried out in 13 F1 hybids and their 16 parents of pepper (Capsicum annutum L.) for their performance of total yield and other 15 characters. Significant positive correlations existed between total yield and early yield, total yield and placenta weidth of fruit,fruit weight and placenta width , single fruit weight and fruit wall thickness, plant height and days to 50% flowering, Vitamin C content and fruit length. Significant negetive correlations were fount between total yield and dry matter content of fruit, fruit weight and fruit number per plant. Fruit number per plant had the greatest direct effect on total yield, width and early yield had marked direct effect on total yield as well, while other characters had only a limited direct effect on total yield. |
