本试验研究与估算了辣(甜)椒10个亲本配制的11个杂种F_2数量性状的广义遗传力,遗传相关及遗传进度的遗传参数。广义遗传力的高低顺序是:单果重>果实纵径>果肉厚>果实横径>单株产量>株幅>株高>始收期>始花期>单株结果数。单株产量同单果重之间的rg、rp,又同单株结果数之间的rg、rp均达到极显著正相关水平,表明可以通过这类性状的表型选择达到提高单株产量的目的。始收期与始花期之间的rg、rp都是极显著正相关,可以通过花期的表型选择达到熟性选择的目的。
This study studied and estimated the genetic parameters of the heritability, genetic correlation and genetic progress of F 2 quantitative traits in 11 hybrids of 10 parents of Spicy sweet pepper. The order of general heritability was as follows: fruit weight> fruit longitudinal diameter> pulp thickness> fruit diameter> yield per plant> plant height> plant height> initial harvest period> initial flowering period> number of single plant results. Rg and rp between single-crop yield and single-fruit weight also reached extremely significant positive correlations with rg and rp between single-crop results, indicating that the purpose of increasing the yield per plant could be achieved through the phenotypic selection of such traits . Rg and rp between the beginning of the initial flowering and the first flowering were extremely significant positive correlation, the phenotype of flowering can be used to achieve the purpose of maturity selection.
