Quality Analysis of Buckwheat (Fagopyrum esculentum Moench) Genotypes of Assam

Sixteen buckwheat germplasm were evaluated for biochemical constituents of quality significance. The germplasm varied significantly in their proximate composition with moisture content ranging from 7.52–9.11%, crude protein from 7.23–9.53%, crude fat 1.97–3.62%, ash 1.83–2.93% and crude fibre from 3.71–4.78% on dry weight basis. Buckwheat flour contained 63.18–72.61% starch consisting of average 23.21% amylose. The resistant starch was found varying between 15.20–20.53%. Total soluble protein ranged from 4.58% to 7.40% with globulin as the major fraction (2.12–3.53%). The buckwheat germplasm contained high level of calcium (0.18%), phosphorus (0.26%) and potassium (0.26%). Total phenolic content was found between 378.41 to 652.71 mg/100g and flavonoids between 33.80 to 60.11 mg/100g on dry weight basis. The local genotypes were found comparable with the released genotypes in their nutrient composition and BWC-1, BWC- 2 and Kharupetia-2 along with buckwheat accessions EC-218742 and EC-27242 were found superior over others in terms of nutritional quality.
