Análise de frações de fibra alimentar em cultivares de feijão cultivadas em dois ambientes

Abstract

The objective of this study was to estimate the dietary fiber fractions in common bean cultivars obtained in different locations, for evaluation of the genotype x environment interaction effects. The dietary fiber was determined by enzymatic gravimetric method in grains of the nineteen common bean cultivars, obtained in 2004/2005 crop season, in two locations of Rio Grande do Sul State, Brazil. Significant genotype x environment interactions were detected for total, insoluble and soluble dietary fiber content and grain yield. The total dietary fiber content varied from 20.85% ('Macotaço', in Santa Maria) to 31.35% ('Macanudo', in Pelotas). The 'Macanudo' and 'Guateian 6662' cultivars showed high total, insoluble and soluble dietary fiber content and its utilization as a regular food in diets can be studied.
