摘要:

白粉病严重危害网纹甜瓜的产量与品质,利用甜瓜自身的抗性基因进行抗病育种是控制白粉病最安全经济有效的途径。本研究通过比较公共数据库中抗性品种(PI414723、MR1)、网纹甜瓜品种(Dulce、Harukei)、甜瓜基因组注释品种(AY)的序列,结合已报道的抗病基因定位区间,开发InDel标记pmc2pi717,并成功将其运用于子代的鉴定。pmc2pi71标记的开发和利用,为今后甜瓜抗白粉病基因聚合育种工作的开展奠定了基础。

Abstract:

Powdery mildew (PM) significantly and negatively affects the yield and quality of muskmelon (Cucumis melo L.var.reticulatus Naud.). Using the resistance genes of melon for breeding is the most economical and environmentally safe way to control powdery mildew disease. Through comparative genome analyses between the PM resistant varieties (PI414723,MR1), the reticulatus cultivars (Dulce,Harukei) and AY (the annonated melon genome),combined with the reported loci of disease resistance genes, we developed a new InDel marker named pmc2pi717 and successfully applied it to the resistance screening in the F2 generation population. This study laid a foundation to pyramid multiple resistance genes into new cultivars in the future via marker assisted selection.
