摘要: 采用RAPD技术,以4个小麦株高基因近等基因系(分别含有rhtRht1Rht2Rht3)为材料,对296个单一随机引物(10个核苷酸)进行了筛选。发现25个引物的扩增产物在近等基因系间表现出特异性。在6次重复试验中,有18个引物的特异扩增片段不能重复,6个引物可以重复2~3次,唯有OPAM01在全部试验中均能稳定重复,其特异扩增片段OPAM011860可以作为rht基因的RAPD标记。

Abstract: Four near-isogenic lines which contained rht,Rht1,Rht2,Rht3 respectively were used for polymorphic analysis at molecular level by RAPD technique. Out of 296 10-mer oligonucleotide primers screened, 25 showed polymorphism among near-isogenic lines. During 6 repeat tests of these primers, 18 could not give the repeat results, 6 could repeat 2 to 3 times, only primer OPAM01 showed the stable results in which a 1.86 kb additional band was found in rht line. OPAM011860 could be identified as a RAPD marker linked to rht gene in wheat.

Key words: Triticum aestivum L, Gene marker, rht gene, RAPD
