Abstract
The phenological, morphological and productivity characteristics of six lentil genotypes (Idlib 1, Idlib 2, Idlib 3, Idlib 4, Balade and Kurdi) were assessed, using some genetic indicators (genetic and phenotypic variance, genotypic and phenotypic correlation coefficients, broad- sense heritability, and the genetic advance between seeds yield and its components at Dmsrkho area, in Latakia during two seasons (2014/2015) and (2015/2016). Randomized complete block design with three replicates was used, in order to investigate as much as possible, the genetic power of the genotypes to exploit them to the fullest extent and determine the appropriate selectorial evidence to improve lentils crop. Analysis of variance indicated that the genotypes differ significantly (P<0.05) for all studied characters. Moreover, years, genotype and years by genotypes interaction were significant for all studied traits. Phenotypic coefficient of variation was slightly higher than genetic coefficient of variation, and heritability values were high for most traits, this indicates the dominance of genetic factors and the low impact of environmental factors. Seed yield/plant (g) had a significant, positive genotypic and phenotypic correlation on number of pods/plant (rg=0.905** and rph=0.907**), while hundred seed weight (rg=0.294** and rph=0.294**) and biological yield (rg=0.76** and rph=0.78**). Biological yield had significant positive genotypic and phenotypic correlation with hundred seed weight (rg=0.62* and rph=0.59*) and seed yield (rg=0.93* and rph=0.95**). This indicates the possibility of selection for the biological yield through the selection of hundred seed weight and seed yield.
