Analysis of variance revealed significant difference among the accessions in leaf length, leaf width, leaf area, number of primary branches, fruit length, bean length, bean width, bean thickness, hundred bean weight and green bean yield. Number of secondary branch, stem girth, fruit traits (fruit length, fruit width, fruit thickness) and bean traits (bean length, bean thickness and hundred bean weight) had the highest positive correlation with green bean yield both at genotypic and phenotypic levels. Bean width and coffee leaf rust had negative correlation with green bean yield both at genotypic and phenotypic levels. Number of secondary branch was the on...

However, the production and adoption of cowpea at the study area is mainly constrained by drought and lack of high yielding varieties. Therefore, the experiment was conducted to identify promising and better yielding improved cowpea varieties for drought tolerance related traits. A total of six improved cowpea varieties were evaluated using a randomized complete block design (RCBD) with three replications at Mieso during the main cropping season of 2018 and 2019. The study identified the superior performing cowpea varieties for different studied traits. The combined analyses of variance revealed the presence of tremendous genetic variation among improved cowpea varieties for all the studied traits, which implies the availability of substantial genetic variation among varieties. Overall, White Wonder and Black Eyebean had better performance compared to the other varieties for yield and the yield related traits. White Wonder (1524.66 kgha-1) and Black Eyebean (1235.69 kgha-1) varieties recorded the highest grain yield and identified as the superior improved cowpea varieties. Therefore, based on the results of adaptation experiment, White Wonder and Black Eyebean were recommended for production and adoption at Mieso and other similar environments.

It plays significant role in collaboration between breeders, farmers, marketers, processors, consumers, and policy makers. It also allows farmers to take part in the development of new varieties more suitable to marginal environments and to organic farming agronomic practices. Several different improved sorghum varieties are released at different international and national research institutions in different times, however the technologies were not properly addressed the farmers based on participatory, client oriented and demand driven. Therefore, the experiment was conducted in Eastern part of Ethiopia of Oromia regional state to evaluate the performance of improved sorghum varieties and to identify farmers' preference traits through continuous performance evaluation at different stages of the crop. Five sorghum varieties along with local check collected from study area were evaluated in randomized complete block design in 2019 main cropping season. Farmers' evaluation was made at two different stages of the crop, namely at flowering and maturity using both direct-matrix and pair-wise ranking methods of selection scheme. Farmers' set; grain yield, disease resistance, grain color and seed size as selection criteria to evaluate and identify their preferred varieties. The results of analysis of variance indicated the existence of highly significant differences among varieties for all traits measured except plant height at 5% probability level. The highest mean grain yield was obtained from the variety Dibaba (11325 Kgha-1) and Jiru (10200 Kgha-1) respectively. Grain yield had positive and highly significantly correlated with thousand seed weight (0.95**) and also positively and significantly correlated with days to 50% flowering (0.85*). Likewise, based on the overall farmer's preference (from both pair-wise and direct matrix ranking evaluations), Dibaba and Jiru were ranked first and second and followed by Adelle, ETS2752 and Chiro respectively. Thus, the varieties Dibaba and Jiru were chosen for their performance in the field and from farmers' evaluation perspective. Moreover, this study indicated participatory varietal selection is a viable method to gain greater insight into farmers' perceptions, preferences, merits and shortcomings of sorghum varieties. Therefore, based on the results of this study, Dibaba and Jiru are recommended for multiplication and distribution to farmers through both formal and informal seed systems. Generally, the integration of plant breeders and farmer's perception used to increase the adoption rate and design a good breeding program for future improvement.

It was executed at Badessa and Doba district of Western Harerghea Zone in main cropping season of 2019. The variety selection process was carried out from different dimensions including utilization, marketing and fi eld performance. Maturity period , cob size, seed size, grain color, disease and pest tolerance/ resistance , market demand and yield were identifi ed as important farmers criteria in the trial sites. Using these criterias the farmers identifi ed varieties that suit their respective location. Accordingly, trial farmers showed special interest to BH 546 and BH 547 varieties. As the preference of the farmers in each sites have already been identifi ed, it will be productive if the extension service consider farmers' preferences in varietal promotion activity and are recommended for further scaling up to reach large small holder farmers through government organizations, Non-government Organizations, research institutes and other stakeholders works on maize technology promotion.

Cup quality determines the relative price as well as the usefulness of a given quantity of coffee. Eighty eight accessions of Coffea arabica L and five standard checks were tested at Tepi National Spice Research Center during the 2016 growing season. The objectives of the study were to assess variation among these genotypes in order to identify and classify genotypes based on cup quality traits. The results showed that very high significant (P<0.01) variation among genotypes for flavor and overall quality, and also significance (P<0.05) for aromatic quality. Genotypes were evaluated using eight cup quality traits by professional coffee tasters at Jimma agricultural research center, Ethiopia. Cluster analysis based on cup quality traits grouped the accessions into four divergent clusters. Shannon-Weaver diversity indexes ranged from 0.31 to 0.7, astringency having the lowest and body cup quality the highest value respectively, ind...

The varieties were laid out in a randomized complete block design with three replications. The environment by variety interaction analysis showed highly significant difference for the varieties, implying that there is best fit cultivar independently for each location. Accordingly, the highest grain yield at Arberekete was revealed by shasho, Habru, Chefe and Kasech consecutively; while at Chiro; Yelibe, Habru, Ejere and Kasech demonstrated top four yield scores. Therefore, Shasho, Habru, Chefe and Kasech varieties were adapted for Arberekete and similar agroecological zones of the western Hararge; Yelibe, Habru, Ejere and Kasech varieties were adapted and promoted for Chiro and similar agro-ecological ...
