Abstract
Information on genetic variability of traits is prerequisite for further improvement of any crops. Currently, under Ethiopia korarima improvement project, large numbers of korarima accessions are collected from different major growing regions of Ethiopia by Jimma Agricultural Research Center (JARC). As far as the variability and heritability among characters in these accessions of korarima is concerned nothing has been done. Therefore twenty five korarima (Aframomum corrorima) germplasm accessions were tested using simple lattice design at Jimma Agricultural Research Center. Data were recorded on 21 characters with the objective of estimating the extent of variation between pairs of characters. Analysis of variance revealed that there was significance difference among the genotypes for the characters studied except internodal length, seed weight and dry matter content. High phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) recorded for bearing tiller, leaf area, and ash and crud fiber content. High heritability coupled with high genetic advance as percent mean were estimated for plant height, bearing tiller, number of capsule per plant, diameter of fresh and dry capsule, ash, crud fiber and oleoresin content; moderate heritability values coupled with higher genetic advance were observed for total tiller, length of fresh capsule, weight of dry capsule, length of dry capsule, volatile oil and crud fat content. This indicates that these characters could be improved through selection.
