Abstract

Finger millet [Eleusine coracana (L.) Gaertn] is an important crop used for food, fodder and industrial purposes. With the objective of increasing the utilization of finger millet germplasm in crop improvement, A composite collection consisting of 1000 accessions was developed and genotypically and profiled using 20 SSR markers. This study reported the genetic diversity and development of genotype based reference set with most diverse 300 accessions. Allelic data on 959 accessions and 20 markers based on quality index was used for further statistical analysis. A total of 231 (121 common and 110 rare) alleles were detected in the composite collection. Gene diversity varied from 0.200 to 0.850. The average frequency of multiple alleles were maximum (13.6%) in race spontanea wild types and ranged from 1.7 to 9.5% in other races. A reference set consisting 300 genetically most diverse accessions was established. This reference set had 206 (89.2%) of the 231 alleles detected in the composite collection, and showed high gene diversity (0.307 to 0.852).
