| variation in physical and chemical characteristics of common bean (phaseolus vulgaris l.) grain along a domestication gradient. | the objective of this study was to compare six samples of mexican wild common bean (phaseolus vulgaris l.) against three landraces and three improved cultivars with respect to physical and chemical attributes, and the culinary quality potential of their grain. a completely randomized experimental design was used to characterize the twelve genotypes. data were analyzed by analysis of variance and pair-wise comparison of the treatment means by the tukey test. in addition, correlation and principal ... | 2011 | 22162159 |
| molecular mapping of genes for resistance to the bean pod weevil (apion godmani wagner) in common bean. | the bean pod weevil (apion godmani wagner) is a serious insect pest of common beans (phaseolus vulgaris l.) grown in mexico and central america that is best controlled by host-plant resistance available in durango or jalisco genotypes such as j-117. given unreliable infestation by the insect, the use of marker-assisted selection is desirable. in the present study, we developed a set of nine molecular markers for apion resistance and mapped them to loci on chromosomes 2, 3, 4 and 6 (linkage group ... | 2006 | 16397789 |
| effect of cultivar and growing location on the trypsin inhibitors, tannins, and lectins of common beans (phaseolus vulgaris l.) grown in the semiarid highlands of mexico. | trypsin inhibitors (ti), tannins, and lectins appear to have a role in preventing chronic diseases in humans. the genetic variability of these traits in common bean needs to be ascertained in order to increase levels through breeding. the variability of ti, tannin, and lectins was determined in five bean cultivars grown at five locations in mexico. ti and tannins contents in colored beans that belong to the jalisco race were higher (11.1-11.9 trypsin units inhibited (tui)/mg and 29.0-38.1 mg cat ... | 2003 | 13129302 |
