- 摘要:
- 为促进专用型高粱选育,采用NCⅡ不完全双列杂交试验设计配制杂交组合,研究高粱单宁的遗传效应。结果表明:在选育单宁含量高的杂交组合时,首先要重视对双亲一般配合力的选择,在选择双亲高单宁含量的同时,注重特殊配合力的应用;单宁性状的广义遗传力较高,在后代中遗传能力很强,且主要受基因控制,受环境影响较小,能稳定传递;单宁的杂种优势较高,在杂交育种中较易获得高单宁的杂交种,但其超高亲优势低,要重点选择双亲平均值高的材料作亲本。
- Abstract:
- In order to promote the selection of special type sorghum,the hybrid combination was designed by NCⅡ incomplete double-column hybrid experiment,the genetic characteristics were studied.The result showed that to breed high tannin conten thybrids,general combining ability of parents should be paid more attention to,meanwhile,in selecting the high tannin content of the parents,the application of special combination should be emphasized.Broad-sense heritability of tannin content was high,and tannin has a strong genetic ability in the offspring,because these traits were mainly inherited by genes,not by enviroment and these traits can be transferred steadily.It was easy to gain hybrids with high tannin,because heterosis of these traits was high.Parents with high mean charactors should be selected,because heterosis of mid-parent was higher than that of over better parents.
