- 摘要:
- 以皖82 -178(抗)×通山薄皮黄豆甲(感)组合衍生的重组近交系群体为材料, 以幼虫重为抗性鉴定指标, 对大豆抗斜纹夜蛾的基因(Q TL)进行SSR 分子标记研究。从大豆公共连锁图谱(Creg an et al ., 1999)7 个与抗虫性可能有关的连锁群上选取了103 对SS R 引物, 鉴定亲本和RIL家系DNA , 其中18 对引物在RIL 家系间表现出多态性。应用t 测验和方差分析法分析SSR 标记与性状的连锁, 并以R2 表示标记对性状变异的解释率。结果在D2 、C2 、H 连锁群上分别找到一个与大豆对斜纹夜蛾抗性有关的SSR 标记, 即Sat t135 、Sat t363 、Satt442 , 单个标记对抗性变异的解释率分别为5 .57 %、2 .89 %、8 .7 %。
- Abstract:
- There have been few reports about molecular marker analy sis of resistance to insect in soybean .Thisstudy w as to determine quantitative trait loci (Q TLs)associated with the soybean resistance to insect (Co ttonWorm)by estimating linkage to simple sequence repeat (SSR)markers.Recombinant inbred lines (RILs)constructed through a cross betw een Wan82 -178 and Tong shanbopihuangdoujia w as used .Larval w eight w as examinedin as index of resistance .Using the interg rated genetic linkage map of soy bean (Cregan et al .1999), wechose 103 SS R markers scattering on 7 linkage g roups (LGs)that had the po tential to map resistant QTL toscreen polymorphic markers betw een Wan82 -178 and To ngshanbopihuangdoujia .It w as found that 18 SSRprimers show ed polymo rphic DNA bands among these RIL lines.Wi th t -test analy sis and analysis of variance ,three markers (Satt135 , Sat t363 , Sat t434)w ere found linked w ith the resistance genes , situat ing on three LGs,i .e .D2 , C2 , and H .The individual ef fect of each marker was reported as R2 value , i .e 5 .57 %, 2 .89 %, and8 .7 % respectively .
