辣椒雄性不育系的品质指标分析

以31份辣椒杂交组合为试验材料,利用品质指标评价方法,研究了辣椒雄性不育系杂交组合,以期为选育加工辣椒提供参考。结果表明:固形物、干物质、维生素C含量、出成率和红色素含量的变幅分别为1.94%～10.56%、10.16%～24.60%、20.31～191.81 mg·(100g)^-1FW、69.61%～76.40%、0.36～13.52 g·kg^-1。利用聚类分析,将31份辣椒杂交组合按5个指标分为五大组群,在维生素C含量上表现出多样性。其中3份材料综合品质好,是选育加工辣椒的优良材料。依据红色素含量进行聚类分析,可以将136份辣椒杂交组合分为六大组群,材料具有很好的多样性。高红色素含量的杂交组合有4份,所占比例较小(2.94%)。筛选出的优质材料可用作培育新品种。

Analysis of Quality Index in Breeding of Pepper Male Sterile Lines

With 31 pepper hybrid combinations as materials,the quality index was used to evaluate the hybrid combinations of pepper male sterile lines in order to provide a reference for the selection and processing of pepper.The results showed that the variation range of the solid content,dry matter,vitamin C content,yield rate and red pigment content was 1.94%-10.56%,10.16%-24.60%,20.31-191.81 mg·(100 g)^-1FW,69.61%-76.40%and 0.36-13.52 g·kg^-1,respectively.Using cluster analysis,the 31 pepper hybrid combinations were divided into 5 groups according to 5 indicators,showing diversity in vitamin C content.Among them,3 materials had good comprehensive quality and were excellent materials for breeding of pepper.According to the cluster analysis of red pigment content,136 pepper hybrid combinations could be divided into 6 groups,and the materials had agood diversity.There were 8 materials with high red pigment content,which account for a small proportion(2.94%).The selected high-quality materials could be used to breed new varieties.
