| 摘 要： | 蔓枯病是由真菌葡萄壳梭孢引起的危害甜瓜生产的主要病害，可以侵染西瓜和黄瓜等其他瓜
类作物，造成不同程度的减产。本文介绍了蔓枯病病原菌的相关研究内容、不同接种鉴定方法对抗性鉴定
结果的影响以及我国近年来审定的部分抗蔓枯病的甜瓜新品种。甜瓜蔓枯病抗性鉴定结果容易受病原菌自
身致病力和外界环境的影响，需要通过相关的分子标记来辅助抗性种质的选育。然而，现有的一些分子标
记还存在很多不足，影响了育种的进程。因此，应该明确不同病原菌之间致病力的差异，选择合适的接种
鉴定方法，不断完善种质资源遗传多样性的评价体系，明确甜瓜种质遗传多样性的分布特点。

| Abstract: | Gummy stem blight（Gsb）is one of the main diseases in melon（Cucumis melo L.），
caused by grape shuttle spore shell，and can infect the other cucurbit crops including watermelon and
cucumber．This disease can result in different degrees of production loss．This paper introduces the
related research progress in gummy stem blight pathogenic bacteria，the effects of different inoculation
methods on resistance identification，and the new melon varieties resistant to gummy stem blight
recently bred in China．The resistance identification results can be easily affected by its virulence and
the environment．Thus relevant molecular markers should be pass to assist the resistance breeding．
However，the existing molecular markers have a lot of deficiencies， which influenced breeding process．
Therefore，researchers should clarify the different pathogenicity of pathogens，choose the appropriate
inoculation and identification methods，and continuously improve the evaluation system on genetic
diversity of germplasm resources，so as to pinpoint the distribution characteristics of melon germplasm
genetic diversity. |
