Abstract

The least cultivated of the Phaseolus domesticates. P. acutifolius Gray, is a unique dry bean grown on a small scale in regions of the world where environmental or pathological stresses do not favor common bean cultivation. It is called tepary (southwestern United States), tepari (Sonora and Sinaloa, Mexico, from an Opata Indian term), tecuzi (Chihuahua, Mexico), and escomite or xmayum (southern Mexico, from Mayan Indian terms)o White seeded types predominate in many regions and hence its name is simply the translation of “little white bean” in the indigenous language. Tepary seeds are smaller than those of most common bean varieties. They have an excellent flavor similar to that of common beans and they can be prepared in much the same manner (NIETHAMMER, 1983).
