Genetic Diversity and Population Structure Analysis to Construct a Core Collection from Safflower (Carthamus tinctorius L.) Germplasm through SSR Markers

Genetic resources are the fundamental source of diversity available to plant breeders for improvement desired traits. However, a large germplasm set is difficult preserve and use as working collection in genetic studies. Hence, present study evaluates 3115 safflower accessions from Indian National Gene Bank, including cultivars, develop manageable accessions, with similar variations studied. A total 18 polymorphic SSR markers were used. The analysis revealed that highly diverse there no correlation between geographical or sourcing germplasm. core was developed using hunter software different levels composition, it found 10% showed maximum gene represented an equal number alleles major allele frequency consisted 351 they validated various parameters ascertain true studied
