Abstract

Lentil (Lens culinaris Medik.) crop plays an important role in both the agriculture sustainability than in food security by providing nutrients to vulnerable people worldwide. However, climate change mainly during flowering and pods filling, impact negatively seed yield and quality. The aim of this study is to select lines with high productivity and good nutritional quality which will be integrated into breeding program of novel varieties development. Thus, current study undertakes the evaluation of 25 advanced lines using nine agro-morphological traits related to seed yields potential and yield components, and total phenolics (TP), total flavonoids (TF) and condensed tannin (CT). ANOVA analysis showed significant variability among lines for almost recorded parameters. The clustering of variability revealed five groups at 85% of similarity. The first cluster grouped earlier genotypes that produced high seeds size (1000-seed weight (41.9g)). The second cluster grouped the high yielding genotypes; while the third one, grouped lines with high polyphenols concentration TP (32.1mgEAG/100g fw), TF (165.5 μgEQ/100g fw) and CT (1010.1 μgEC/100g fw). The fourth cluster regrouped lines with high potential of seedlings (59.8%) and yield potential according to total pods number per plant(142), fertile pods plant-1 (111), number of seeds plant-1 (156), and weight of seeds plant-1(4.30g). The last cluster included one line (LN-52) that was distinguished with its high performance for almost all recorded parameters. The selection of lines (LN-03, LN-62 and LN-52) is proposed to be used in lentil breeding programs.
