利用抗、感矮化病毒病的花生品种ICGV86699和远杂9102为亲本配制杂交组合,构建重组近交系群体(RIL),采用SSR技术和BSA分析方法,结合F6各个家系接种病毒后ELISA的鉴定结果,得到1个与花生矮化病毒病抗性连锁的分子标记XY38。此标记与抗性基因间的遗传距离为7.5cM,具有作为抗性育种辅助选择技术的潜力。
F6 plants of a peanut RIL population derived from Yuanza 9102(susceptible line)×ICGV86699(resistant line) combination were used to identify DNA markers for resistance to peanut stunt virus(PSV) in peanut by SSR and BSA method.Based on ELISA results,an SSR marker XY38 linked to PSV resistance was identified with 7.5cM between marker and the resistance gene.
