Abstract

Curcuma amada Roxb. (mango ginger) of the family Zingiberaceae is an under-exploited spice and tuber crop which grows luxuriantly on tropical soils. Being a marginalized crop, conservation and improvement are very important for the popularization of the crop as a food component, for product diversification and also for effective conservation of the genotypes. In Kerala, local landraces are being used extensively for cultivation and they show very high level of variability with respect to growth and yield. In this context a study was carried out during 2005–2009 to collect and conserve the available germplasm of mango ginger from Kerala and to evaluate their genetic potential. Fifty diverse accessions collected were evaluated in RBD in the first crop season for three consecutive years by adopting standard management practices. All the 15 growth/yield characters studied showed significant variation indicating the strength of the genetic base of the crop. Among the characters, the highest variability was observed in yield/plant followed by tiller number, leaf area and plant height. Accession No. CUM 34 showed the highest performance index with 494.44 g yield/plant followed by CUM 35 with 450 g yield/plant.
