Two new varieties were tested on-station between 1984/85 and 1992/93 cropping seasons in replicated trials in six environments, compared with other varieties and controls in Malawi. Their performances were verified. Results from these 14 locations confirmed superiority of the two elite sorghum varieties tested. Based on significant yield differences (62 and 73 per cent higher grain yield) of the two sorghum varieties relative to PN 3 (in station trials) and (2 and 31 per cent higher yield) relative to LLV Thengalamanga (in on-farm tests), the two varieties from ICRISAT, SPV 351 and SPV 475, were released in Malawi as Pirira 1 and Pirira 2
