Abstract:
A field experiment to study the genetic variability, correlation and path analysis for seven quantitative characters in early maturing thirty-one desi Chickpea lines was conducted at Agricultural Research Station, Adilabad, Professor Jayashankar Telangana State Agricultural University, Hyderabad. All the characters under study i.e., Days to 50% flowering, plant height, number of primary branches, number of secondary branches, number of pods per plant, test weight and grain yield showed significant mean sum of squares indicating the presence of significant variability among the test genotypes. The estimates of genotypic and phenotypic coefficients of variability were high for the traits, number of pods per plant and grain yield. High phenotypic coefficient of variability and moderate genotypic coefficient of variability was observed for the trait, number of secondary branches. Moderate levels of Phenotypic and Genotypic Coefficients of Variability were observed for the trait, number of primary branches. Moderate Phenotypic Coefficient of Variability and low Genotypic Coefficient of Variability were recorded for the traits, plant height and test weight. Low Phenotypic and Genotypic Coefficients of Variability was observed for the character, days to 50% flowering. High heritability coupled with high genetic advance over mean was observed for the traits, number of primary branches, Number of secondary branches, Number of pods per plant and grain yield per hectare. High heritability coupled with high genetic advance over mean indicates the presence of additive gene action for the traits, and their response to selection. Grain yield was significantly and positively correlated at genotypic and phenotypic levels with the traits; days to 50% flowering, number of secondary branches, number of pods per plant and test weight. Genotypic Path analysis revealed that, the characters; plant height (0.09797), number of primary branches per plant (0.12687), number of pods per plant (0.40957) and test weight (0.77133) showed positive direct effects.
