Abstract:
To identify elite collections to be employed in breeding programs, studies on genetic variability, heritability, and genetic advance as percent of mean were conducted among thirteen collections of red ginger. The results showed maximum phenotypic and genotypic co-efficient of variation for characteristics like yield per plant (GCV = 64.03%; PCV =65.05%) followed by length of inflorescence (GCV = 61.93%; PCV = 67.54%). The highest possible heritability values were attained in yield per plant (96.89%) followed by length of inflorescence (91.09%). High genetic advance as a percentage of the mean and a high heritability estimate were found for yield per plant (78.97%) followed by length of inflorescence (76.08%). High heritable variability was found for characters like days taken for flower bud initiation, length of inflorescence, girth of spike at the base, number of bracts per spike, fresh weight of stem, vase life and spike yield which can be used in future crop breeding programmes.
