Abstract

Genetic diversity and fusarium resistance of 50 cultivated chickpea genotypes was studied using ISSR and RAPD markers. The results of both marker systems were consistent with each other, but was somewhat higher for RAPDs. A total of 48 fragments were obtained with both markers together, 32.7% of which were polymorphic. Molecular characterisation through ISSR and RAPD data indicated low genetic variation (GDI=0.39; PIC=0.21) among local and introduced chickpea accessions. The genetic distance values ranged from 0 to 0.134, with a mean of 0.05. The low genetic diversity indicated that new genotypes must be introduced to increase the variability of chickpea germplasm in Azerbaijan. As a result of screening for resistance to fusarium most of genotypes were found to have 600 bp fragment of OPJ20 linked with Foc01 resistance gene, while none of them had resistance gene to Foc4. The results could provide information for future chickpea breeding activities and conservation.

DNA标记在鹰嘴豆抗枯萎病及遗传多样性测定中的应用

利用ISSR和RAPD对50个栽培鹰嘴豆基因型的遗传多样性和抗病性进行了研究。两种标记系统的结果一致，但rapd的结果略高。两种标记共获得48个片段，其中多态片段占32.7%。通过ISSR和RAPD数据进行分子特征分析，遗传变异低(GDI=0.39;本地鹰嘴豆和引种鹰嘴豆的PIC=0.21)。遗传距离为0 ~ 0.134，平均值为0.05。阿塞拜疆鹰嘴豆种质资源的遗传多样性较低，表明必须引入新的基因型来增加其多样性。通过对镰刀菌的抗性筛选，大多数基因型的OPJ20均与Foc01抗性基因有600 bp连锁，而对Foc4抗性基因均无连锁。研究结果可为今后鹰嘴豆的育种和保护提供参考。
