Interpretive Summary: Heat and drought stresses threaten global bean production. Additional genetic resources are needed in genebanks for future improvement of bean crops through breeding for tolerance to heat and drought among other stresses. The southwestern Sky Island mountains contain such genetic resources, wild beans, that have not been adequately collected nor characterized. Continuing the work done in 2023, a 9-day exploration in 2024 in southern New Mexico and Arizona for wild teparies and other Phaseolus species resulted in the collection of herbarium, pressed plant samples, and seed samples of 18 populations of P. acutifolius (tepary bean), one each of P. angustissimus and P. filiformis, two of P. grayanus, three of P. maculatus and three of P. montanus, or 28 populations in total.

Samples of nodules and soil of rhizosphere were also collected. Outcomes and ways to improve
