- 摘要:
- 以引进和选育的23份贵州紫心甘薯种质资源为试材,采用形态标记方法,研究了材料间的遗传多样性,以期为紫心甘薯新品种选育提供参考。结果表明:‘13-24-2’和‘13-24-7’的欧氏距离最近为0.25;‘13-4-2’和‘13-24-2’的欧氏距离最远为5.62。可将23份贵州甘薯种质资源分为3类,第一类包括16份;第二类包括6份;第三类只有1份。
- Abstract:
- Twenty-three introduced and breeding germplasm resources for purple sweetpotato in Guizhou were used as test materials.Genetic diversity among the materials was studied by cluster analysis of morphologic characteristic in order to provide theoretical guidance for new varieties breeding of purple sweetpotato.The results showed euclidian distance for ‘13-24-2’ and ‘13-24-7’ was 0.25,which was the nearest;the farthest euclidian distance was 5.62 for ‘13-4-2’ and ‘13-24-2’.The 23 Guizhou purple sweetpotato varieties could be classified to three groups,the first class included 16 germplasms;the second class included 6 germplasms;the third class only included one germplasm.
