- 摘要:
- 以2年生白花桔梗和紫花桔梗为试验材料，测定二者主要性状的遗传参数，研究桔梗各性状间的相互关系。结果表明：2年生紫花桔梗在开花期和结果期的根重、分枝数、开花数3个性状变异系数较大，均在25%以上；且根重、主根粗均与开花数呈极显著正相关。2年生白花桔梗在开花期和结果期根重、分枝数、主根长、开花数变异系数较大，均在25%以上，且根重与茎粗、分枝数均呈极显著正相关。因此，紫花桔梗育种可通过开花数间接选择根重，也可以通过根重直接进行高产类型的选育；白花桔梗育种可通过分枝数间接选择药材丰产性状根重。
- Abstract:
- Taking the biennial white flower P.grandiflorum and purple flower P.grandiflorum that from Jilin as the materials，their variance of genetic parameters of main quantitative trait and the correlation between different characters were studied.The results showed that in the flowering period and the fruiting period，the biennial purple flower P.grandiflorum root weight，the number of branch and the number of flowering had larger variation coefficient，all above 25%；their root weight and main root thick had significantly positively associated with the number of flowering.The biennial white flower P.grandiflorum root weight，branch number，main root length and the number of flowering had larger variation coefficient，all over 25%;their stem diameter，the number of branch had significantly positive associated with the root weight.Therefore，purple flower P.grandiflorum breeding could through the selection of number of flowering choose root weight，also could choose root weight for the breeding of high yield type.White flower P.grandiflorum breeding could through the branch number choose root weight.
