Rust disease caused by Uromyces viciae-fabac is one of the most destructive diseases of pea (Pisum sativum) in north India. Tolerance to rust disease in peas is dominant over resistance in the F, generation of resistant x tolerant crosses. There is a single gene difference between the resistant (JP 4) and tolerant (FC 1, EC 1 and P 930) parents. The gene for tolerance in FC 1 is different from that of EC1 and P 930 and the tolerance genes are non-allelic. EC1 and P 930 have the same gene for tolerance.
