Abstract

Assessing variability and correlations for agro-morphological traits of lentil are the important aspects in the development of lentil varieties. Six lentil genotypes were evaluated in randomized complete block design (RCBD) with four replications at Agronomy Research Farm of Institute of Agriculture and Animal Science (IAAS), Paklihawa, Rupandehi, Nepal during winter season of 2018/19 to assess the genetic variability, heritability and genetic advance for agro-morphological traits. Analysis of variance revealed significant differences for all traits. The values of Phenotypic Coefficient of Variance (PCV) were higher than Genotypic Coefficient of Variance (GCV) for all the characters, and the number of pods per plant exhibited high estimates of both PCV and GCV indicating substantial scope of improvement through selection. The number of secondary branches showed the highest PCV (0.89) and GCV (0.50) whereas the lowest PCV (0.02) and GCV (0.00) were recorded for date to 50% maturity. High heritability (0.62) coupled with high genetic advance (192.63) as percent mean was observed for the grain yield. Grain yield showed positive and significant phenotypic correlation with number of pods per plant (r=0.424) and plant height (r=0.420). The highest positive direct effects were observed in plant height followed by number of grains per pods, number of secondary branches and number of pods per plant; suggesting the importance of these characters and the necessity of adopting them as selection criteria for grain yield improvement.

Key words: Lentil, Grain yield, Heritability, Correlation, Path analysis.

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.
