This paper presents the results of collecting missions undertaken from 2008 to 2011 and assessment of seed diversity of indigenous lentil (Lens culinaris) germplasm in Oman. 11 seed samples/accessions of lentil were collected of which Al-Dhahira & Buraimi governorates had the highest (6), followed by South Batinah-coastal governorate represented by mountains of Rustaq (3) and Al-Dakhliya (Interior) governorate (2) with no contribution from other agriculturally important Sharqiya (eastern), North Batinah and Southern Dhofar governorates. Seed accessions were diverse with respect to four seed traits investigated like seed length (cm) and width (cm), 1000-seed weight (g) and seed color. Seed length varied from 0.33 cm to 0.45 cm; seed width ranged from 0.320 cm to 0.405 cm and 1000-seed weight ranged from 22.5 g to 32.5 g. With respect to seed color, the accessions were classified into five groups based on simple to complexity of color combinations with scores from 1-5 with varying frequencies / numbers. These accessions were grouped into 4 genetically diverse clusters corresponding to their spread in four quadrants of the biplot graph based on the Principal Component Analysis (PCA) using seed traits which showed substantial contribution of seed length (38.095 %) followed by seed width (32.930%) and 1000-seed weight (28.733%), with the least contribution by seed color (0.242%) to the first principal component (PC1 or factor 1). Of the six-character combinations, only two correlation coefficients viz. between seed length and seed width (0.864*) and between seed length and seed weight (0.710*), were significant (p<0.05).
