Abstract: The experiment on genotypic variability, heritability and genetic advance for yield and yield contributing characters in fourteen Alpinia galanga (L.) Willd accessions were carried out at the Division of Floriculture and Medicinal crops, ICAR-IIHR, Bengaluru during the year 2019-20. Data were recorded on the parameters like plant height (cm), leaf length (cm), leaf width (cm), leaf area (cm²), petiole length (cm), inflorescence length (cm), Flower bud size (cm), pedicel length (cm), relative height between androecium and gynoecium (cm) and yield/tiller (g). The genotypic coefficient of variation was less than the phenotypic coefficient of variation in all the characters studied. The phenotypic coefficient of variation as well as the genotypic coefficient of variation was higher for the characters like petiole length, leaf area and inflorescence length. Broad sense heritability values showed high heritability for characters like petiole length (83.35%), plant height (74.47%), leaf length (68.95%), which was on par with leaf area and inflorescence length (68.03%) and pedicel length (64.87%). The Higheest estimates of GAM were recorded for traits like petiole length (52.72%), inflorescence length (31.26%), leaf area (29. 38%) and pedicel length (23.47%).
