Genetic Diversity Analysis of Pepper Inbred Lines

In order to use the pepper germplasm adequately, the genetic diversity of pepper inbred lines was analyzed by using SSR markers. The genetic diversity analysis of pepper inbred lines was performed with 12 polymorphic, stable and reliable SSR markers. 60 bands were amplified and the percentage of polymorphic loci was 100% with an average of 5 alleles per locus. The genetic similarity coefficients ranged from 0.33 to 1.00 among these inbred lines, indicating that the genetic diversity was significant in these materials. The cluster analysis results showed the genetic relationship of pepper germplasm was related to geographic origin and agronomic traits.
