Sesame (Sesamum indicum L.) is one of themost important oilseed crops with high oil contents and richnutrient value. The development of a core collection couldfacilitate easier access to sesame genetic resources for theiruse in crop improvement programs and simplify the genebankmanagement. The present study was initiated to the developmentand evaluation of a core collection of sesame basedon 5 qualitative and 10 quantitative trait descriptors on 2,751sesame accessions. The accessions were different countriesof origin. About 10.1 percent of accessions were selectedby using the power core program to constitute a core collectionconsisting of 278 accessions. Mean comparisons using t-test,Nei's diversity index of 10 morphological descriptors andcorrelation coefficients among traits indicated that the existinggenetic variation for these traits in the entire collection hasbeen preserved in the core collection. The results from thisstudy will provide effective information for future germplasmconservation and improvement programs in sesame.Keywords : core collection, development, evaluation, samplingstrategy, sesame germplasm
