摘要
水稻香型恢复系昌恢121分别与非香稻品种大粒稻、9311、02428、R527、C418、明恢63配制杂交组合,并采用KOH法对其后代的香味进行鉴定,研究分析了昌恢121的香味的遗传模式。并利用昌恢121与现有的香稻材料粤香占、苏香晚占杂交配成香/香组合,并进行香味基因的等位性分析,结果表明:供试香稻品种昌恢121的香味是由1对显性基因和1对抑制基因所控制,且与粤香占、苏香晚占的香味基因不等位,因此,昌恢121的香味涉及2对以上基因的控制,且不等位间的基因存在互作效应。
In this paper,the genetic mode of the aroma of aromatic rice restoring line Changhui 121 was analyzed by KOH method through the respective hybridization between Changhui 121 and non-fragrant rice varieties 9311,02428,R527,9311,C418,R527,Minghui 63.The allelism of the aroma genes in Changhui 121 was analyzed by the crossing between Changhui 121 and aromatic rice materials Yuexiangzhan,Suxiangwanzhan.The results showed that the aroma character of Changhui 121 was controlled by a pair of dominant genes and a p...
