SUMMARY V4604, a Cambridge University accession of Phaseolus vulgaris , had a high degree of leaf resistance to race 1 of Pseudomonas phaseolicola and partial resistance to race 2. Genetic control of resistance to race 1 was by a major dominant gene which is also present in the cv. Red Mexican. The partial resistance of V4604 to race 2 was under polygenic control, as was the low level resistance to race 2 in V4058.
