ICPL87 pigeonpea (Cajanus cajan) was developed by pedigree selection from the cross ICPX73052 (T21 X JA277), made in 1973. In various Indian trials, it outyielded the control, UPAS120, by up to 50%, giving 3700-5200 kg/ha. ICPL87 matures 110-130 days after sowing. Plants are smaller than in conventional longer duration types and suitable for high density (330 000 plants/ha) cultivation; they are 80-90 cm tall and semispreading, with a determinate growth habit. ICPL87 is tolerant of Fusarium udum wilt and compensates strongly during the second flush for damage caused by pod borer (Heliothis armigera [Helicoverpa armigera]).\ud\u
