Abstract

A study on mutagenic studies in black turmeric (Curcuma caesia Roxb.)” was carried out at College of Horticulture, Mudigere during the year 2021-22. Black turmeric is an underexploited medicinal plant of Zingiberaceae family. Since it is a vegetatively propagated crop, induction of mutation and isolation of desirable mutants are the means for producing genetic variability. Mutagens like gamma rays (10, 15, 20, 25, 30, 35 Gy), EMS (1, 1.25, 1.5 %) and colchicine (0.1, 0.2, 0.3 %) were used along with untreated control. The experiment was laid out in RCBD design with thirteen treatments and two replication. There was a slight difference between GCV and PCV for all the characters indicating they were least affected by the environment. High heritability coupled with high genetic advance over percent mean were observed for all the yield parameters which indicates that these traits are under the influence of additive gene action which can be improved through selection.

Keywords

Black turmeric, GCV, PCV, heritability, genetic advance over percent mean

Conclusion

Mutation treatment resulted in creation of variability in the existing black turmeric population. A moderate to high estimate of GCV and PCV were recorded for all the growth and yield parameters. High heritability coupled with high genetic advance over per cent mean were noticed for the all the yield parameters.
