- 摘要:
- 细菌性果斑病是由果斑病菌(Acidovorax citrulli)引起的病害，该病害是种传病害，对瓜类产业构成了巨大的威胁。以130份甜瓜种质资源为试验材料，采用种子浸种接种果斑病菌的方法鉴定幼苗的抗病性，研究甜瓜种子带菌对幼苗生长的影响。结果表明:供试材料中没有表现免疫的材料；表现为高抗的材料有2份，为NM90-1、M867，相对抗病指数分别为0.967、0.899，可以作为抗病育种的种质资源。中抗材料为32份，中感材料为54份，感病材料42份。
- Abstract:
- Bacterial fruit blotch (BFB) caused by the bacterium Acidovorax citrulli，the disease is seed borne diseases，posing a huge threat to the melon industry.Taking 130 samples of muskmelon germplasm as material, the effect of muskmelon seeds with pathogens on the growth of seedlings was studied by using the method of seed soaking to inoculate Acidovorax citrulli to identification of resistance in seedlings.The results showed that no immune materials,and the germplasm resources of muskmelon copy of NM90-1,M867 showed high resistant，relative resistance index were 0.967，0.899；moderately resistant material were 32 copies，moderately susceptible materials were 54 copies，sensitive materials were 42 copies.NM90-1，M867 showed high resistant to bacterial fruit blotch，they could be used as germplasm resources of resistant breeding.
