Telia and teliospores of Phakopsora pachyrhizi, causal fungus of rust of soybean (Glycine max), were formed on Cajanus cajan (pigeon pea), Glycine canescens (wild soybean), G. javanica, (wild soybean), G. wightii (wild soybean, lines K-51394, PI 277534, and PI 319474), G. max (cultivar TK5, PI 230970, and PI 230971), Pachyrhizus erosus (yam bean), Phaseolus lunatus (lime bean), Phaseolus vulgaris (common bean), Rhynchosia minima, and Vigna unguiculata (cowpea) when the hosts were inoculated and grown in a growth room programmed for a 12-hr photoperiod (2,060 lux), 60100% relative humidity, and diurnal temperatures between 24 1 C minimum night temperature.
