Abstract:

The genetic diversity and the population structure of 183 germplasm resources of eggplant were analyzed by using SRAP markers. Overall, 215 bands were generated with 7 binds per primer on average. The mean genetic similarity coefficient was 0.623 among the cultivars (0.276-0.813), which suggested genetic differentiation among the germplasm resources. The germplasm resources were divided into four groups with a similarity coefficient of 0.345 6. Introgression exists in the four groups based on population structure analysis. The boundaries among different groups are obvious, and gene introgression among varieties is high.

Key words: eggplant, genetic diversity, population structure, SRAP analysis
