图2 不同Wx等位基因特异分子标记的检测
A图为利用QRM190分子标记区分Wx^a和Wx^b的PCR检测结果, 泳道1为3611, 2为9311, 3~7为近等基因系NIL(Wx^b); B图为利用基因特异分子标记区分Wx^a和Wxⁱⁿ的PCR检测结果, 泳道1为3611, 2为IR64, 3~7为近等基因系NIL(Wxⁱⁿ)。

Fig. 2 Detection of specific molecular markers for different Wx alleles
(A): allelic specific molecular marker QRM190 for detecting Wx^a and Wx^b. Lanes 1-7: 3611, 9311 and their derived NIL NIL(Wx^b) (lanes 3-7), respectively. (B): allelic specific molecular marker for detecting Wx^a and Wxⁱⁿ. Lanes 1-7: 3611, IR64 and their derived NIL NIL(Wxⁱⁿ) (lanes 3-7), respectively.
