Title: Genetic Diversity of Salt-Tolerent Eggplant Cultivars by SRAP and ISSR Markers
Abstract: Genetic diversity in 14 salt-tolerant eggplant cultivars were assessed using sequence related amplified polymorphism (SRAP) and inter simple sequence repeat (ISSR) makers. These results suggested that there was a high level of genetic diversity among 14 salt-tolerant eggplant cultivars, and ISSR makers were superior to SRAP. In SRAP analysis, each primer could amplify 8 to 15 polymorphic bands with an average of 12.12 bands. A total of 315 bands were observed in 26 primers, among which 263 bands were polymorphic and the percentage of polymorphic bands (PPB) was 83.49%. Among the eggplant accessions, the SRAP-based genetic similarity (SRAP-GS) ranged from 0.212 to 0.923 with a mean of 0.755. In ISSR analysis, the number of bands from each ISSR marker ranged from 5 to 16 with an average of 10.87. A total of 163 bands were detected, among which 141 bands were polymorphic and the PPB was 86.50%. The ISSR-derived genetic similarity (ISSR-GS) ranged from 0.333 to 0.957 with a mean of 0.736. The cluster analysis indicated that all satl-tolerant eggplant accessions could be distinguished by both SRAP and ISSR markers. Mantel test indicated that SRAP and ISSR markers were significantly associated (r=0.904, P0.01).
