Abstract
Seedlings from six crosses between susceptible x resistant and two bet ween susceptible parents were screened against P-3 isolate of Phytopht hora drechslerif. sp. cajani in the glasshouses. Disease reaction was scored on a rating scale of 1-5. Resistance was found to be controlled by one dominant gene and some minor genes and is affected by ontogeny . The resistance gene appeared to be different from the one reported e arlier (Pd-1) and is designated here as Pd-3.
