An array of resistant lines has been generated at ICRISAT, from selections within segregating natural hybrids from the USA and from many crosses made between resistant germplasm accessions and agronomically superior but susceptible parents. Advanced breeding lines, with good yield potential, have been entered in national trials in India. The resistant lines are suitable for oil expressing but pod and seed characters need to be improved for their use as confectionery products. Some of the breeding lines also have resistance to other biotic and abiotic stresses. Preliminary studies on the genetics of rust resistance indicate that 2 or 3 duplicate recessive genes are involved in conferring resistance. Quantitative data revealed significant additive, additive × additive and additive × dominant gene effects involved in resistance.
