Interspecific hybridization between seven Canajus cajan genotypes viz., ICPL 88039, ICPL 11253, ICPL 11256, ICPL 11265, ICPL 11333, ICPL 11300, and ICPL 11306 with the wild species C. scareboides were attempted during kharif 2018. Successful pod set was observed in direct crosses involving C. cajan as ovule parent and C. scareboides as pollen parent while the reciprocal crosses were failed to set pods. The only surviving F1 of ICPL 88039 × C. scareboides, ICPL 11253 × C. scareboides, ICPL 11306 × C. scareboides and ICPL 11300 × C. scareboides were vigorous in growth and exhibited variation in leaf, flower, pollen fertility, plant habit, pod colour and seed morphology with predominance of C. scareboides plant type. Seed size variation was observed in all crosses. With respect to test weight, cross ICPL 88039 × C. scareboides have 4.80 g seed weight while its parents have 2.33 g and 10.10 g, male and female respectively. The partial homology coupled with seed set suggested the possibility of incorporating traits of economic importance such as pest resistance from C. scareboides into C. cajan.
