Genetic variability, Correlation and Path coefficient analysis for yield and yield components in lentil (Lens culinaris M.) genotypes

Genetic Variability and Character Association Study for Yield and Attributing Traits in Lentil (Lens culinaris Medikus.) under Terai Agro-climatic Conditions of West Bengal

“…The variable effect of environment on the expression of the studied characters was validated with the phenotypic coefficient of variation being higher than the corresponding genotypic coefficient of variation for the characters which was in consonance with the observation reported by Vanave et al [15], Debbarma et al [16], Chowdhury et al [17], Bicer and Sakar [18], Haddad et al [19], Solanki [20] and Pandey et al [21]. High broad sense heritability was observed for all the characters under present investigation ranging between 66.50% to 98.13%; similar observation in lentil have been reported by Crippa et al [22], Chowdhury et al [17], Singh and Srivastava [23], Bicer and Sakar [18], Tyagi and Khan [14]. The range of genetic advance as percent of mean was classified as suggested by Johnson et al [9].…”

“…The yield plant -1 showed a significant and positive correlation with the characters viz., primary branches plant -1 (0.905), secondary branches plant -1 (0.416), pods plant -1 (0.846) pod weight plant -1 (0.992) and harvest index (0.432). The positive association between seed yield and primary branches plant -1 and secondary branches plant -1 was also reported by Singh and Shrivastava [23], Solanki et al [20], Kumar et al [28] and Chowdhury et al [17]. Plant height revealed a significant positive correlation with secondary branches plant -1 (0.406) and the number of seeds pod -1 while pods plant -1 was significantly and positively associated with primary branches plant Further partitioning of the total correlation as performed through path analysis and presented in Table 5 to study the direct and indirect effect of yield attributing characters on the yield revealed a residual effect of 0.0233 thereby establishing the effect of genotypes on the studied association.…”

“…The above interpretation on the effects of attributing characters on yield has been presented after Lenka and Mishra [33]. Chowdhury et al [17] similarly reported that days to maturity, number of primary branches plant -1 , pod plant -1 and 100 seed weight had positive direct effect on seed yield plant -1 . The highest positive direct effect of pods weight plant -1 and significant positive association with yield plant -1 suggested that selection for this trait could be instrumental for improvement of economic yield in lentil.…”

Assessing Genetic Parameter, Correlation and Path Coefficient in Spontaneous Mutant Progenies of Lentil (Lens culinaris Medikus ssp. culinaris) Variety DPL 62

“…Leaflet length and plant height revealed moderate GCV along with high heritability and genetic advance which pointed towards presence of lesser variability for these traits in the material studied; however, they can be improved through selection to a limited extent. These results are in partial agreement with the findings of Hussan et al, (2018), Chowdhury et al, (2019), Kumar (2020), Kumar et al, (2020) and Sharma et al, (2022).…”

Evaluation and path analysis for yield and its components in some genotypes of lentil (Lens culinaris Medikus) under Upper Egypt condition

“…High heritability for days to flowering, plant height, no. of pods plant -1 , 100-seed weight and harvest index and moderate for seed yield plant -1 were obtained by Sharma and Singh (2014), Chowdhury et al (2019) and Vanave et al (2019). Lentil area and production is declining for the last years due to the low yield potential of lentil varieties.…”
