ABSTRACT: The present study was conducted
in 4 × 4 half diallel cross fashion using the genotypes named as NL-2002,
NL-2006, Punjab Masoor-2009 and Markaz-2009 for the evaluation of gene action
in the inheritance of economic traits of lentil by following the Griffing
(1956) Method of analysis. Minirap 13.1 Copyright© 2000,
Minitab inc. Method II, Model I was used for the analysis and gene action was
computed by variance component analysis using Mixed Model with GLM (general
linear model) procedure. The F1 direct crosses along with the
parental genotypes were then evaluated by framing the experiment in RCBD in 3
replications. The data were recorded for the characters which are under the
study are, plant height (cm), number of primary branches, number of secondary
branches, number of pods per plant, number of seed per pod, seed yield per
plant, biomass (gram), 100 seeds weight (gram), harvest index (%), yield per
plant. The simple ANOVA for all the characters revealed that difference among genotypes
was highly significant. As significant differences were present between the
genotypes, it permitted subsequent analysis of the data. The Combining Ability
(CA) results showed that value of variance for GCA (General Combining Ability)
was significantly higher than that of those of the values of variance of SCA
(Specific Combining Ability). Hence current results clearly depicted the role
of additive type of gene action governing the characters under study.
