摘要
以筛选出来的69份无刺红花资源为材料,利用相关性分析及聚类分析对其花瓣色价、单株果球数、单株果球种子数、果球直径、百粒重、单株种子产量、单株花瓣产量7个性状进行评估。结果表明:69份材料间存在较大的差异,对红花种子产量贡献最大的农艺性状是单株果球数;对红花花瓣色价进行分析,将69份红花资源分为3类,色价在6.3~14.1之间,其中色价极高型材料有14份,平均值达到12.38。对7个性状指标进行综合聚类分析,可以将69份红花资源分为5大类群,各类群性状变化丰富,其中组Ⅳ综合表现最好,是选育高色价、高产红花的优良材料。69份红花资源在色价和产量指标等方面表现出多样性,遗传较丰富,但色价高的资源材料相对较少。红花种质资源色价及主要产量性状的综合分析,可为红花资源的有效利用及选育高色价、高产红花新品种奠定基础。
In this study,the phenotypic traits including color value,number of fruit per plant,number of seeds per plant,fruit ball diameter,weight per 100 seeds,yield per plant and petal yield per plant were investigated by using 69 non-thorn safflower（ Carthamus tinctorius L.） germplasm accessions. The results showed that there were significant differences among the 69 materials and the agronomic trait that contributed the most to the safflower seed yield was the number of fruit bulbs per plant. Based on analysis of color value of the safflower petals,the 69 safflower germplasm resources were divided into 3 groups. The color value ranging from 6. 3 - 14. 1,of which 14 were very high-color value materials with an average value of 12. 38. Based on cluster analysis on 7 characters,the 69 safflower germplasm resources were divided into 5 main groups,the characters of each group were different and the differences were abundant. The group-IV have the best overall performance,which were chosen as excellent resources for safflower breeding. Safflower breeding resources showed great diversity in color value and yield characters,but the resources with high color value had small proportion. The comprehensive analysis of color value and main yield traits established foundation to efficiently utilize the safflower germplasm resources in breeding for new safflower varieties with high color value and high yield.
