Characterization of Nutritional and Process Quality of Some Faba Bean Varieties and Advanced Lines Grown at Bale, South Eastern Oromia

Abstract

Faba bean is said to be poor man’s meat as it is the most important protein source for most of world’s population. Field experiment was carried out at Sinana and sinja site if Goba districts of Bale highland to see the effect of faba bean genotypes and growing environment on some physico-chemical and nutritional qualities of faba bean genotypes. For this experiment, fifteen faba bean genotypes including released and promising lines were evaluated for their physico-chemical quality characterization. From the result it was seen that most quality characters measured have shown significant variation (p<0.05) due to faba bean genotypes. The nutrient contents of the grains of the test genotypes across two testing environments, crude protein vary from (22.43-24.34%), phosphorous (0.62-0.70%), sodium (405-262.31 ppm), potassium (1.77-1.40 gm/100gm), calcium (932.08-830.32 ppm) and hydration potential vary from (2.12 to 2.04%) which fall under high to sufficient nutrient content when compared to nutrient composition of plant material. Genotypes EH07006-51, EH070015-7, EH07006-1 and EH0773-8 have got better quality characters as compared to the released varieties Shallo, Mosisa and the local check. Genotype EH07006-1 is better in percent hydration, Na and K composition as compared to the other test genotypes. From the collected data it is possible to conclude that genotypes EH07006-1, EH07006-51, EH070015-7 and EH0773-8 are better to be selected for the variety verification.
