Field experiments were carried out at Serere Agricultural and Animal Production Research Institute (SAARI) and Ngetta Experimental Station to evaluate the yield performance of short-duration pigeon pea lines. The study was conducted in two stages; on-station and on-farm trials. On-station trials were carried out during first rains of 1993, 1994 and 1995, while on-farm trials were carried in Lira district during the first rains of 1996 and 1997. Twelve improved pigeon pea lines were evaluated and Apio-Elina local pigeon pea variety was used as check (control). Improved pigeon pea line gave higher yields than the local variety. Amongst the improved lines, KAT 60/8 and ICPL 87091 consistently gave high yields across the sites and years. Highest yield 3200 kg ha-1 was obtained from KAT 60/8, while the lowest yield (570 kg ha-1) was from the local variety. KAT 60/8, ICPL 87091, ICPL 87102 and ICPL 87104, performed well and were selected for on-farm testing. Results from on-farm trials indicated that KAT 60/8 and ICPL 87091 performed better that the other two and were then recommended for release. KAT 60/8 was then named as SEPI 1 while ICPL 87091 named as SEPI 2.
