Article Info Thirty-three accessions and three released varieties of black cumin genotypes were field evaluated at Debre Zeit Agricultural Research Center during 2015 main season using 6x6 simple lattice Design. The objectives were to assess the genetic variability, correlation coefficients of yield and its component traits into direct and indirect effects through path analysis. Analysis of variance showed significant differences among accessions for most of the traits, Partitioning the total variation revealed that, the genotypic coefficients of variation (GCV) was high for seed yield per plot. On the other hand, phenotypic coefficients of variation (PCV) were high for seed yield per plot and seed yield per plant. High broad sense heritability was not associated with high genetic advance for all characters under consideration. Although, moderate heritability and high genetic advance was obtained for flower duration and seed yield per plot. The phenotypic correlation was positive and significant for seed yield per plant with plant height, biomass per plot, seed yield per plot, days to maturity and harvest index. The genotypic correlation was positive and significant for yield per plant with days to maturity, plant height, biomass per plot, thousand seeds weight, and harvest index. Path coefficient analysis indicated that biomass per plot, days to 50% flowering, days to maturity, plant height, number of locules, harvest index, and seed yield per plant revealed positive direct effect on seed yield. In contrast, days to first flowering, flower duration and thousand seeds weight had negative direct effects on seed yield. Thus, there is enormous opportunity to use the existing accessions for direct selection as well as using distant parents for crossing purposes to improve specific traits.
Even if there are released Fenugreek varieties in Ethiopia, there is no variety specifically for color quality purpose. This study was conducted based on the objective of evaluation of different colored Fenugreek germplasm for yield and market preference in Ethiopia. Evaluation and preliminary variety trial were conducted at Debrezeit, Chefe donsa and Akaki locations. While national variety trial was conducted at Debrezeit, Chefe donsa, Akaki, Kulumsa, Sinana, Gonder, Sirinka, and Assosa having nine genotypes including check variety. The standard experimental procedures were used in the experiment. The result showed that, there is a significant difference among tested genotypes over locations; however, the objective of the experiment is to evaluate nine fenugreek genotypes including check variety considering both market seed color preference and yield. The study found FG-10(Bishoftu) variety had white seed color. This color is preferred color in international market. This variety therefore, was released for production for all fenugreek growing environments of East Shoa and similar environments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
