Leguminous plants belong to the family Fabaceae and play a crucial role in human nutrition and agriculture due to their high-protein content and nitrogen-fixing ability. This study aimed to evaluate the amino acid composition of lentil (Lens culinaris L.) and common bean (Phaseolus vulgaris L.) genotypes grown under standard agronomic conditions. The analysis of variance revealed significant (P ≤ 0.01) differences among the 46 lentil and 15 common bean genotypes for yield-related traits. The results disclosed that 21.7% of the lentil genotypes were high-yielding, 45.7% were medium-yielding, and 32.6% were low-yielding. In common beans, 33.3% of the genotypes were high-yielding, 26.7% were medium-yielding, and 40% were low-yielding. The results provided a tangible basis for forming core and trait collections from the national gene fund, supporting breeding programs aimed at improving protein quality and essential amino acid profiles in lentils and common beans.
Lentil (L. culinaris L.), common bean (P. vulgaris L.), yield potential, yield-related traits, breeding
Significant genetic diversity was evident among the lentil (L. culinaris L.) and common bean (P. vulgaris L.) genotypes for both quantitative and qualitative traits. This diversity represents an important resource for plant breeders, offering opportunities to enhance the protein content and nutritional quality through targeted breeding strategies.
