Seed morphology, quality traits and imbibition behaviour study of atypical lentil (Lens culinaris Medik.) from Rajasthan, India

摘要

An atypical morphotype of lentil (Lens culinaris Medik.) was identified during mega germplasm characterization programme at ICAR-National Bureau of Plant Genetic Resources, New Delhi undertaken during rabi 2017-2018. On the basis of the comparative evaluation of lentil morphotype with two distinct subspecies, viz., L. culinaris subsp. macrosperma and L. culinaris subsp. microsperma, this atypical morphotype was classified under the latter subspecies. Based on comparative study with selected accessions for seed morphology, quality traits and physiology, this accession was identified with very distinct and prominent funiculus on the seed coat, higher rate of water uptake and nutritional traits (rich in sugar, starch, protein and minerals). Present studies identified this germplasm as unique type that deserves for the detailed study to explore its genetic resource potential.
