Registration of “Bullaallaa” Newly Released Durum Wheat ( Triticum turgidum L.) Variety for Bale Mid and Highland Areas

摘要

Durum wheat is the major staple cereal crop in Ethiopia. Including checks 20 durum wheat genotypeswere evaluated in randomized complete block design (RCBD) with three replications. The study was took placefor two consecutive years during 2012 and 2013 main cropping season at four locations, namely; Sinana, Agarfa,Ginir and Gololcha representing of the major durum wheat growing areas of South Easter of Ethiopia. Theobjective of the study was to evaluate the most stable, high yielding, disease resistant and quality durum wheatgenotype for mid and highland areas of Bale. The analysis of variance (ANOVA) showed significant (p 0.01)variation among varieties for all traits. After evaluation of genotypes across location and years Bullaallaa witha pedigree designation of “Durum ICARDA/Ethiopia PDYT-322” was selected and verified for one year atmultilocation during 2016. Bullaallaa is a common name given for thisnewly released durum wheat variety.The study found that Bullaallaa (Durum ICARDA/Ethiopia PDYT-322) variety had above average yieldperformance in most tested environments, out yielded for Tate, Toltu and Ingilizechecks. The mean grainyield across locations and years of Bullaallaa was 56.4quintal per hectare. It was more yielder, stabile, diseaseresistant and uniform than checks. Finally, it was evaluated by National Variety Releasing Committee andrecommended for release in 2017 for the studied area and similar agro- ecologies.
