Performance Evaluation of Improved Oat Varieties/Accessions at the Highland of Guji Zone, Bore, Ethiopia

Usman Semman


This study was conducted with an objective of introducing, adapting, see the yield, quality and recommends improved Oat accessions/varieties to the area in a randomized complete block design (RCBD) with three blocks. Accessions/varieties was (CI-8251, CI-8235, CI-8237, Lampton, Jasari, SRCPX80Ab2291, SRCPX80Ab2806, 79Ab384 (TX) 80SA95, 79Ab384 (TX) 80SA94 and Grayalegris), Bonsa and Bonabas. The analysis of data revealed that CI-8251 proved to be the highest biomass yielder accession, and as regards the other characters, it was found to be the highest in plant height, seed yield, harvesting index (HI) and less susceptible to disease and have no lodging, which reflects its better characteristics. 79 Ab384 (TX) 80SA94 was significant in seed yield and HI and less significant in disease attack and has short date of flowering and maturity and no lodging, where as JASARI was significant in disease attack and has short date of maturity and less significant in seed yield.. SRCP x 80Ab2806 was highest in Crude Protein (CP) content than the rest accessions followed by Grayalegris and 79 Ab384 (TX) 80SA94. Bonsa and Bonabas varieties are also good both in yield and quality aspect specially NDF content. Generally from this it is concluded that, considering all the agronomic and yield parameters accessions, CI-8251 was superior followed by 79 Ab384 (TX) 80SA94 and from quality analysis aspect SRCP x 80Ab2806 and Bonsa and Bonabas varieties both yield and quality aspect was selected and recommended to the area so that farmers are using for their livestock feed and go for further demonstration.
