“…This variability can be explained because there was significant variation in the origins of the 53 lines used in the study, which included lines developed by several Brazilian research institutions and lines introduced from other countries. Other studies have also reported differences in CFe and CZn among different lines of the common bean Araújo et al, 2003;Ribeiro et al, 2008;Silva et al, 2012;Jost et al, 2013).…”

ABSTRACT. The common bean is an important source of iron and zinc in humans. Increases in the contents of these minerals can combat mineral deficiencies, but these contents are influenced by environmental conditions. Thus, the objectives of this study were to investigate the interaction between common bean lines and water availability on iron and zinc contents (CFe and CZn, respectively), identify superior lines with stable CFe and CZn, and test for a genetic relationship between CFe and CZn. Six crop trials were performed using a randomized block design with three replications. The trials were performed during the winter sowing period for three different combinations of year and site in Brazil. For each combination, 53 lines were evaluated across two parallel trials; one trial was irrigated according to the crop requirements, and the other trial operated under a water deficit. Interaction was detected between lines and environments, and between lines and water availability for CFe and CZn. However, some lines exhibited high CFe and CZn in both conditions. Lines G 6492 and G 6490 exhibited high mean values, stability, and adaptability for both minerals. Other lines exhibited high CFe (Xamego) or CZn (Bambuí and Iapar 65). A

“…Iron and zinc deficiencies affect about 40% and 33%, respectively, of the people in the world (The Word Bank, 2006). The potential of beans for biofortification for iron and zinc has been evaluated, and the obtained results are promising (Blair, 2013;Jost et al, 2013;Petry et al, 2015;Teixeira et al, 2015). Biofortification for potassium, phosphorus and copper has not been reported in the literature for beans.…”

The objective of this study was to estimate genetic parameters for agronomic and nutritional traits in four common bean populations with biofortified grains for minerals, and to identify the superior population for these traits. Thus, four common bean populations were obtained by controlled crossings between parents contrasting for potassium (P 1 ), phosphorus (P 2 ), zinc (P 3 ) and copper (P 4 ). A total of 40 lines in F 6:8 generation of each population and nine parents were evaluated in two field experiments (rainy season of 2012 and dry season of 2013) in the state of Rio Grande do Sul, Brazil. The studied populations presented genetic variability for cycle, insertion of the first pod, grain yield, and potassium, phosphorus and zinc concentrations in grains. Heritability estimates and selection gain of intermediate and high magnitude were obtained for cycle, insertion of the first pod, grain yield, and potassium concentration in grains in P 2 . In P 4 , insertion of the first pod, grain yield and phosphorus and zinc concentrations in grains presented high heritability and selection gain estimates. From the tested crossings, it is possible to select common bean inbred lines biofortified for potassium, phosphorus and zinc and with high agronomic performance.

“…Mesoamerican and Andean common bean seeds have a large genetic variability for iron, and values from 29 to 159 mg kg -1 dry matter (DM) have been reported Blair et al, 2010aBlair et al, , 2010bJost et al, 2013;Ribeiro et al, 2014aRibeiro et al, , 2014b, which allows for the selection and use of iron-rich cultivars for human consumption.…”

-The objective of this work was to evaluate the main differences in the genetic control of the iron concentration in Mesoamerican and Andean common bean seeds, in early generations, and to select recombinants with a high iron concentration in the seeds. F 1 , F 1 reciprocal, F 2 , F 2 reciprocal, and backcross (BC 11 and BC 12 ) generations were produced by crosses between Mesoamerican (CNFP 10104 x CHC 01-175) and Andean (Cal 96 x Hooter) inbred lines. The expression of significant maternal effect was observed for the Mesoamerican gene pool. Iron concentration was higher in the seed coat of Mesoamerican common bean seeds (54.61 to 67.92%) and in the embryo of Andean common bean seeds (69.40 to 73.44%). High broad-sense heritability was obtained for iron concentration in Mesoamerican and Andean common bean seeds. Gains with the selection of higher magnitude, from 20.39 to 24.58%, are expected in Mesoamerican common bean seeds. Iron concentration in common bean seeds showed a continuous distribution in F 2 , which is characteristic of quantitative inheritance in Mesoamerican and Andean common bean seeds. Recombinants with high iron concentration in seeds can be selected in both Mesoamerican and Andean common bean hybrids.
