> Evaluation of Malt Barley ( Hordeumdistichon L.) Genotypes for Grain Yield and Malting Quality Parameters at Koga Irrigation in Western Amhara Region

摘要

Background and Objective: Malt barley production demand increased due to the establishment and production capacity increment of malt and beer factories in Amhara Region. It is difficult to fortify the demand of malt and beer factories in the region only under rain fed production. Therefore, to evaluate and recommend malt barley varieties, the study was conducted at Koga irrigation experimental site of Adet Agricultural Research Center with the objective of selecting high grain yield ing malt barley varieties with acceptable malt qualities to boost malt barley production the irrigation areas. Material and Method: Twelve released malt barley varieties were tested in 2013 and 2014 irrigation session in randomized complete block design with three replications. Data of Plant height, days to heading, days to maturity, spike length, number of seeds per spike and grain yield data were collected and malt quality data grain protein and starch content of the varieties were analyzed using NIRS in Amhara agricultural research institute grain quality laboratory. Result: In the combined analysis Variety EH 1847 showed the highest grain yield (5.73 t ha ~( -1 ) ) while Holker had showed the lowest grain yield 3.2 t ha ~( -1 ) . IBON 174/03 was the early to head (61.67) and Sabini was early to mature 102.8 days respectively. Conclusion: Variety Sabini which showed higher grain yield and acceptable protein content 5.1 t ha ~( -1 ) and 11.07% respectively recommended for malt barley production. However, the activity should be repeated both over years and across locations to explore seasonal variation and environmental factors on malt barley genotypes grain yield and quality.
