Tepary bean is a highly abiotic stress tolerant orphan crop for which there has been limited research on its nutritional value and cooking characteristics. These are key aspects when considering the potential for broader adoption of tepary bean. Therefore, the goal of this study was to evaluate a large set of seed composition and cooking traits related to human nutrition using both landraces and breeding lines of domesticated tepary bean from replicated field trials and to compare the traits in tepary with those in common bean. Tepary bean showed reduced fat and ash concentration and higher sucrose concentration as compared to common bean. Of the twelve amino acids evaluated, only proline in one of the two trials was statistically different between the two species. There were statistically significant differences between tepary and common bean for the concentration of some elements in this study; however, the elemental concentrations fell within the range of those found for common bean in previous studies. The majority of tepary bean lines showed consistently short cooking times and a high percentage of seeds showed measurable water uptake, while some showed a hardshell trait (low water uptake) and longer cooking times. Principal component analysis on a subset of traits showed a distinct group of common beans and two tepary bean groups that were divided on the basis of several agronomic, cooking, and elemental composition traits. Tepary bean, as with other pulses, is a highly nutritious crop with the range of composition and cooking characteristics similar to those of common bean. The variability for seed composition and cooking traits found within tepary bean can be exploited for its improvement. 相似文献

The optimal plant growth habit and architecture of common bean (Phaseolus vulgaris L.) is dependent on environmental conditions. The objectives of this research were to determine if plant growth habit impacts
a plant’s ability to grow in low P conditions, as measured by P uptake, seed yield, and P use efficiency and to determine
if aboveground plant growth habit and root growth are associated at variable P soil levels. The study was carried out with
recombinant inbred lines developed from an Andean intra-gene pool cross between a low P tolerant parent with an indeterminate
growth habit (G19833) and a low P susceptible parent with a determinate growth habit (AND696). The population was grown for
2 years in low and sufficient P conditions in a field site in Darien, Colombia. In the first season, indeterminate lines had
15% more seed yield than the determinate lines in the low P treatment, whereas there was no difference by growth habit in
the high P treatment. In the second season, seed yield and tolerance to low P was not influenced by growth habit. Root architectural
characteristics such as root length density (RLD) and root surface area were 25% and 34% greater respectively in the indeterminate
lines under P-sufficiency, whereas under low P, root architecture traits were not significantly different by growth habit.
Root plasticity was higher in determinate lines, although RLD and root surface area did not play a significant role in tolerance
to low P. Overall, the data were consistent with shoot growth habit as playing a complex and important role in adaptation
to P-deficiency. 相似文献
