Genetic variability, heritability and genetic advance in turmeric (Curcuma longa L.) germplasm under Gangetic alluvial plains of West Bengal
Author(s): Venugopal S and Pariari A
Abstract: The genetic variability, heritability and genetic advance over mean were estimated for yield and quality traits in five turmeric germplasm. Wide genetic variation was observed for all genotypes like plant height, yield per plot, number of leaves per plant and curcumin content. Considering genetic parameters, high GCV was found for curcumin content (52.69%) followed by yield per plot (19.07), number of primary rhizomes per clump (14.20) and number of leaves per plant (14.02) respectively. In all cases, phenotypic variances were higher than the genotypic variances except girth of primary rhizomes which were found exactly same. Based on high heritability (h2bs) oleoresin content (99.59%), yield per plot (98.63), number of primary rhizomes per clump (97.59), number of leaves per plant (96.75) and length of primary rhizomes (96.72) were found superior and high GAPM was observed for curcumin content (108.34%), yield per plot (39.01) and number of primary rhizomes per clump (28.90) found superior traits and representing additive genetic variance. Effective selection would be made considering these traits.
