“…In line with the current finding [25], reported a positive and substantial link between tiller per plant and yield per plant, as well as a negative association between crude fiber content and yield in turmeric. Similarly [26,27], in fenugreek found that pod per plant and pod length had a positive connection with yield per plant. Likewise [28], found a substantial and positive relationship between the number of capsules per plant and the yield per plant.…”

In Ethiopia, the spice Korarima is one of the most important cash crops. The Jimma agricultural research institute recently gathered a large number of Korerima genotypes from Ethiopia's key growing regions to analyze genetic variations between genotypes and produce varieties. However, no characterization or genetic variability research has begun in these korerima collections. Thus, character association and path coefficient analysis was performed on twenty-five Korarima germplasm samples collected from various agro-ecological regions of Ethiopia to estimate the extent of correlation between characters at the phenotypic and genotypic levels, and compare the direct and indirect effects of the characters on yield. Each incomplete block has a 5 × 5 simple lattice design with two replications and five accessions in Jimma agricultural research center during the 2020 main cropping season. Nine plants were planted in each plot, with a row and plant spacing of 1.8 m. The genotypes were grown under Sesbania shade trees. At both the genotypic and phenotypic levels of significance, yield per plant had a positive and significant relationship with the total tiller, bearing tiller, number of leaves per stem, number of capsules per plant, the weight of fresh capsule, and length of dry capsule, indicating the possibility of correlated response to selection. The number of capsules per plant had the greatest direct effect on yield, according to genotypic path analysis. This proves that the correlation is real and that direct selection using these features will be quite effective. The diameter of the dry capsule, total tiller, dry capsule weight, and fresh capsule length all have a direct positive effect on yield. Varietal, environmental, and edaphic elements, as well as management practices, might all contribute to the variation. The findings might help with future breeding and quality-improvement efforts.
