Abstract:The experiment was carried out toevaluate the performance of mustard varieties for yield and yield components traits with specific adaptation. Therefore an experiment was initiated to assess yield and yield components trait of mustard varieties that are best suited to the western shewa zone of the Oromiya Regional state.The experiment was carried out in Randomized Complete Block Design in three replications at Holetta research center. The results of combined analysis of variance showed that, varieties were significantly different for seed yield, oil content, oil yield, date of flowering, date of maturity, primary branches indicating that the presence genetic variability for improving these traits, while none significant for number of seeds, number of pods, plant height and number of secondary branches. More important components of yield for the tested mustard varieties were number of seeds per plant, number of primary branches per plant, number secondary branches per plant and number of pods per plant. Based on these major traits of yield components three genotypes namely PGRC/E 208585, PGRC/E 208528/2, PGRC/E 208556gave comparable seed yield, oil content, oil yield, number of seeds per plant and these varieties were also comparable for their reaction to major disease. These varieties with the highest yield component characters can be selected for the improvement and grown in western zone of Shewa.
