Sirinka Agricultural Research Center, North Wollo, Ethiopia
The field experiments was conducted at Kobo, Mersa and Chefa testing sites of Sirinka Agricultural Research Center in1999 and 2000 seasons for varieties adaptation and 2004 and 2005 seasons for genotypes selection. The experiments were conducted in randomized block design using three replications with the objectives of selecting adaptable variety for the lowland areas of Wollo. Analysis of variance for each environment revealed significant differences across the tested environments and from adaptation experiment variety Abasina is high seed-yielder (12.33 qt ha-1) and had low deviation from linear regression coefficient implying its stability for different environments. Therefore, Abasina was recommended for the lowland areas of northeastern Ethiopia and from genotype selection, Pungun yonggae showed stable performance and gave high seed and oil yield across the tested environments providing a seed and oil yield advantages of 99.0% and 94.9%, respectively over the standard check, while Kelafo 74 x C-22 sel 4 had specific adaptation to more favorable environments with a seed and oil yield advantages of 106.3 and 116.7%, respectively over the standard check. Therefore, based on their performances, Pungun yonggae and Kelafo 74 x C-22 sel 4 were officially released for production with the name of Borkena, and Ahadu respectively.
