Abstract

Ginger is grown as a number of landraces and locally popular cultivars in Karnataka, India and there is a need for the assessment of variability present among landraces and locally popular cultivars growing in Karnataka. Therefore, a set of 45 ginger collections were collected from several parts of Karnataka was subjected to field evaluation in augmented block design by using four checks in four blocks. This investigation was conducted to study the genetic variability of ginger collections for growth and yield parameters. For all of the parameters studied, there was a broad genetic variation among the collections; high PCV and GCV was recorded in dry rhizome yield per hectare, followed by rhizome yield per hectare, length of the primary rhizome, rhizome yield per plant and number of secondary rhizome, respectively. In every case, high phenotypic variances were observed than the genotypic variances. Depends on high heritability together with high genetic advance as per cent of mean, number of secondary rhizomes, length of the primary rhizome, rhizome yield per plant, length of secondary rhizome, girth of secondary rhizome, girth of primary rhizome and number of primary rhizomes were identified as superior traits and exhibit additive genetic variance. These characteristics would be considered in effective selection.

Conclusion

The growth and yield characters evaluated had genotypіc and phenotypіc coefficіent of varіation in the present study. That demonstrates the genetic diversity of ginger grown in Karnataka, India. The number of secondary rhizomes, length of the primary rhizome, rhizome yield per plant, length of the secondary rhizome and girth of the secondary rhizome were estimated to have hіgh heritability together with hіgh genetic gain, indicated that clonal selection for these parameters can be successful in ginger.
