A field experiment was conducted at the Kulumsa Agricultural Research Center in Southeast Ethiopia during the meher season (July to November 2019 and 2020) to evaluate the extent of variability, heritability, and genetic advance of eight yield and yield-related variables among 25 Ethiopian coriander accessions. A 5×5 simple lattice with two replications was used to arrange the accessions. The combined analysis of variance revealed highly significant differences (P< 0.01) for the eight examined traits. The results showed a large degree of variation in all traits that were studied, pointing to the possibility of simultaneously boosting yield and traits that are related to yield. The estimated broad sense heritability (H2b) ranged from low for seeds per umbel and thousand-seed weight during the first and second growing seasons, respectively, to very high for seed yield (t ha-1), number of umbel plant-1, and number of umbellets umbel-1. The seed yield plant-1 (g), seed yield (t ha-1), and number of umbellets umbel-1 were shown to have the highest genetic advances as a percentage of the mean (GAM (%)). According to these findings, cultivar selection based on traits of high H2b in combination with high GAM (%) could enhance offspring performance and increase coriander yields. The results had practical implications for breeders and farmers. More investigation is compulsory to identify processing qualities and assess the phenotypic and genetic diversity among Ethiopian coriander accessions. [ABSTRACT FROM AUTHOR] |
