为了研究ISSR标记与韭菜杂种优势的对应关系，在对27个韭菜杂交组合及其父母本性状调查的基础上，计算植株分蘖数等5个性状的杂种优势，并把分蘖数、单株质量和鞘长的杂种优势与父母本的ISSR标记遗传距离进行比较分析，结果表明，强优势杂交组合多数集中在父母本遗传距离≥5.0的位置。

In order to study on the corresponding relationship between ISSR markers and heterosis of leek ,this paper calculated the heterosis of tiller number and other traits ,and compared the of heterosis of tiller number ,plant weight and sheath length with ISSR genetic distance of the parents based on the investigation of the traits of 27 hybrid combinations of leek and their parents .The inquiry elicited the strong heterosis was mostly concentrated in the position of genetic distance over 5 .0 .
