Chinese Abstract

採用RAPD技術對中國38個啤酒大麥品種的遺傳資源進行了聚類分析。結果表明:從篩選出的28個有多態性的隨機引物中,共擴增出153條譜帶,其中91條譜帶具有多態性,占59.4%。每個引物可擴增出1~8條多態性譜帶,平均3.3條。聚類分析表明,在遺傳距離GD值0.27水平上38個啤酒大麥品種可聚成兩大類,下分5個亞類。品種間遺傳距離GD變幅為0.00952~0.37846。RAPD標記揭示出這38個啤酒大麥品種遺傳變異較小,遺傳基礎比較狹窄。

English Abstract

The genetic relationships among 38 genotypes of beer barley from China were investigated by RAPD. The results showed that 28 arbitrary primers produced 153 distinctive bands in total and 91 of them were found to be polymorphic, which accounted for 59.4%. Each primer could amplify 1 to 8 polymorphic bands with an average of 3.3 bands. Cluster analysis showed that 38 beer barley could be classified into 2 groups at the level of GD 0.27, which were respectively classified into 5 subgroups again. The GD varied from 0.00952 to 0.37846. Most beer barley had showed certain regular distribution in every subgroup. The results indicated that the genetic basis of them was rather narrow.
