Implication

Study reveals genetic variability and clustering of groundnut genotypes, suggesting effective phenotypic selection.

Key Points

  • Significant genetic variability was identified among groundnut genotypes for yield traits, indicating potential for improvement.
  • High heritability and genetic advance were recorded for key yield traits, suggesting additive gene action predominates.
  • Mahalanobis D² analysis grouped genotypes into five clusters, aiding in identifying distinct parents for breeding.
  • The biological yield per plant contributed most to total genetic diversity, highlighting its importance in breeding programs.
