Abstract

The preliminaries characterization of a collection of twenty three Algerians accessions of lentil (Lens culinaris M.) were done before sown. Seed thickness (STH), Seed diameter (SDM), thickness/diameter ratio (T/D) and Weight of 100 seeds (WHS), are a quantitative traits measured. Altitude and Rainfall of location of origin of accessions are considered as a supplement variables. Also, qualitative characters: Grain form (GFR), Ground color of seed testa (GCT), Pattern of testa (PAT), Cotyledons color (COC), were considered. From the result of Principal Component Analysis (PCA), axis 1 explains 65.08% of the variance in the qualitative character and it showed a strange negative correlation with seed diameter (SDM), Weight of 100 seeds (WHS) and altitude (ALT).Whereas, it was positively and significantly correlated with thickness/diameter ratio (T/D) variable. The second component, accounting for 23.58 % of the total variation, was correlated positively with seed thickness (STH). Hierarchical discriminate analysis revealed major differences between accessions from different regions. Three major regional groups were apparent: 1) a Western group characterized by accessions of the Macrosperma type, 2) a more Northern group of the Microsperma type and 3) A mixture group gathered all regions and the two types. Regarding qualitative traits, the application of Multiple Correspondence Analyses (MCA) showed that seeds with globular form (Microsperma) are two types: 1) Brown or green tasta with dotted seed coat pattern or note and yellow cotyledons and 2) Brown tasta with orange cotyledons. In addition, seeds with flat form (Macrosperma) are divided into two types: 1) Brown, Beige or Green tasta with yellow cotyledons, 2) Brown tasta with dotted seed coat pattern and yellow cotyledons.
