    Abstract

    Sixty pigeon pea [Cajanus cajan] accessions collected from different agroecological zones in Sri Lanka and 10 control lines representing different maturity groups were evaluated during the 1990-91 main rainy (maha) season at Maha Illuppallama. Plots were hand weeded and sprayed with insecticides 3 times. The results showed that the germplasm available in Sri Lanka contains considerable variation for important agronomic traits. The long-duration types often found in backyards are not suitable for commercial production due to their excessive height and susceptibility to pod borers and pod fly. The short-duration group has a narrow variability for flowering, maturity and height, and some were superior in yield to the control cv. ICPL87. Major insect pests can be managed in the short-duration types, and when sown under high density with good management practices, they can yield 1.0-1.5 t/ha.
