| Résumé : |
The major area of sorghum production in Malawi is the Lower Shire, major constraints to production have been: lack of suitable cultivars, unsatisfactory cultivation practices, drought and pest damage. Current sorghom breeding work has identified new varieties which are superior to those currently being grown. Two new varieties have been tested on-station between 1984/85 and 1992/93 cropping seasons in replicated trials in six environments, compared with other varieties and controls. Their performances have also been verified in 1992/93 in on-farm trials, compared with farmer varieties at eight locations in two districts of Chikwawa and Nsanje in the Lower Shire. Results from these 14 environments provide usable data to confirm superiority of the two elite sorghum varieties tested.
Based on significant yield differences (62 and 73% higher grain yield) of the two sorghum varieties relative to PN 3 (in station trials) and (2 and 31% 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.
