摘　　要：以12份不同来源的线辣椒自交材料为研究对象,采用方差-协方差分析法,对12份线辣椒的主要数量性状的遗传参数和相关性进行估算分析。结果表明:株高、单果种子数、单株结果数、单株产量、单果质量、单果干鲜比等6个性状具有较强的遗传效应,适于在早期世代进行选择,且性状改良难度较小,其余性状选择效率较低,改良难度较大;相关性分析发现存在6对极显著正向相关的性状,1对极显著负向相关的性状。12different sources inbred materials of line pepper were selected and treated by variance and covariance analysis,and 12 genetic parameters of the main quantitative characters in these materials were estimated and analyzed.The results showed that,the plant height,seed number per fruit,fruit number per plant,grain yield per plant,ratio of dry weight per fresh weight etc.six traits had an admirable genetic effect,these characters were suitable for selection in early generation,and easy to improve.The other traits were less efficient,and it was difficult to improve.The correlation analysis showed that there were 6pairs of significantly positively traits and 1couple of highly significant negative traits between these characters.
