摘　　要：本研究利用Cmpmr2F隐性基因序列鉴定50份甜瓜资源材料,通过PCR扩增,利用与甜瓜白粉病抗性共分离的分子标记筛选抗白粉病的甜瓜资源,从50份资源材料筛选出了14份抗白粉病的资源材料、25份感性资源材料、11份杂合型抗性材料。这些材料经过田间进一步验证后,可以用于杂交育种,配制抗性杂交组合。Using Cmpmr2F recessive gene sequence to identify 50 melon resources,PCR amplification,and the resistant resources to powdery mildew were screened by using molecular markers which were separated from the resistance to powdery mildew of muskmelon.The results showed that 14 resistant materials and 25 susceptible materials 11 hybrid resistant materials were selected from 50 resistant materials.These materials could be used in cross breeding to make resistant cross combinations after further verification in the field.
