LONDERO, Patrícia Medianeira Grigoletto; RIBEIRO, Nerinéia Dalfollo and CARGNELUTTI FILHO, Alberto. Fiber content and yield grain in common bean populations. Ciênc. agrotec. [online]. 2008, vol.32, n.1, pp.167-173. ISSN 1981-1829. http://dx.doi.org/10.1590/S1413-70542008000100024.
The development of bean cultivars with high grain yield and high dietary fiber content is desirable, thus objective of this study was to evaluate genetic variability for fiber content and grain yield in segregant populations of the black common bean. Crossings were performed inside a greenhouse among the parents CNFP 8100, FT 96-1282, Varre Sai and BRS Valente. The populations obtained (F1, F1 reciprocals, F2 and RC) and parents were assessed in the field during spring/summer 2003/04, using a complete randomized blocks experimental design. Significant differences were not obtained for crude fiber, soluble fiber, insoluble fiber, dietary fiber and grain yield, although contrast parents were used. In this go, it was not possible to obtain segregant populations with genetic variability of the crossing among the parents CNFP 8100, FT 96-1282, Varre Sai and BRS Valente. The populations obtained showed high soluble, insoluble and total dietary fiber content.
