Drought tolerant crops and high protein leguminous crops that include
tepary bean (Phaseolus acutifolius) have over the years been largely ignored and neglected by research as minor crops.
Fertile backcross and allotetraploid plants from crosses between
tepary beans and common beans.
They subsequently used the multiple-needle and razorblade inoculation techniques to develop dry bean breeding lines with the highest level of resistance to common bacterial blight from the common x
tepary bean interspecific populations.
"Our goal must be something beyond blue corn chips,
tepary bean dips, amaranth candy, sunflower seed snacks and ornamental chiles.
Interspecific hybrids between common and
tepary bean were first obtained with a great deal of effort by Honma (1956) for a few genotypes, including a Great Northern line and four
tepary bean accessions.
Interspecific hyridization between common and
tepary bean: Increased hybrid embryo growth, fertility, and efficiency of hybridization through recurrent and congruity backcrossing.
Tepary beans thrive in hot, dry conditions, and they have a remarkably high protein content that ranges between 23 percent and 30 percent.
Domesticated and wild
tepary bean: Field performance with and without drought stress.
Both lines, XAN 263 and XAN 309, derive their CBB resistance from the
tepary bean, and also possess small red seed, Type II growth habit, and I gene for BCM resistance.
Field performance of selected
tepary bean germplasm in the tropics.

tepary bean (P.
(1998b) observed disease severity was correlated with yield loss in
tepary bean (Phaseolus acutifolius A.
