    摘要:

    本文用灰色关联方法分析了40份湖南辣椒地方品种资源和12个杂交组合.结果表明,辣椒果实干物质、Vc和辣椒素含量、TMV、CMV和炭疽病抗性与第一花节位、株高、株幅、分枝数等植株性状的关系较近,与果长、果宽、单果重量、结果数和单株产量等果实性状的关系较远.根据灰色关联度的大小,从湖南辣椒地方品种资源中筛选出重要育种材料有伏地尖、河西牛角椒和湘潭晚辣椒,从杂交组合中筛选出优良杂交品种湘研1号、湘研3号、湘研5号、湘研9号和湘研10号,这些材料和品种均在育种和生产中发挥了重要作用,说明灰色关联分析方法能够用于指导辣椒育种.

    Abstract:

    Forty accessions of local pepper cultivars in Hunan and 12 combinations of hybrids were analyzed with grey relation grade method. The results indicated that the contents of dry matter, Vc and capsaicin in fruit, resistances to TMV, CMV and anthracnose were more related with the first flower node, plant height, plant spread and branches per plant, etc., but comparatively less related with fruit length, fruit width, weight per fruit, fruit setting number and yield per plant. According to their grey relation grades, some important breeding materials such as Fudijian, Hexinliujiaojiao and Xiangtanwanlajiao were selected from these resources, and excellent hybrid pepper varieties Xiangyan 1, Xiangyan 3, Xiangyan 5, Xiangyan 9 and Xiangyan 10 have been successfully bred from the cross combinations, and all of them have played an important role in pepper breeding and production in the country. It implied that grey relation grade analysis can be used to guide the pepper breeding.
