| 摘 要： | 摘要：为了对现有色素辣椒品种资源进行色价的评估，以便于为其专用品种育种提供参考依据, 采用类平均法对109份色素辣椒的色价聚类分析，依据遗传距离将其可划分为5类群：极高型、优型、较高型、普通型和极低型；109份辣椒的色价介于4.72～33.34，当前主栽品种的色价均值近12；不同遗传型色价极差为5～23.95，变异系数13～29%，表明品种资源中色价存在着丰富的差异性和多样性；甜色素椒是高色价育种的优势类群；杂优利用中须重视筛选高特殊配合力的组合。 |

| Abstract: | Abstract: In order to assess the color value unite of the Paprika red chilli resources, and provide a reference for its special varieties of breeding grounds, by using group average method the hierarchical cluster was made on 109 dry chilli materials based on the color value unite. The results showed that the 109 materials could be divided into five categories: the extreme high content type(G1), the excellent type(G2), the high content type(G3), the normal type(G4) and the low content type(G5). The color value unite of 109 materials was between 4.72～33.34, the range of different gene types was 5～23.95 and the variation coefficient was 13～29%. It showed that variety resources that exist in the rich color value differences and diversity; sweet pepper is a high-pigment color value the advantages of breeding group; heterosis utilization of screening must pay attention to a combination of high specific combining ability. |
