Résumé fourni par la source

Investigations were conducted at Chiyako in Jigawa State situated in the Sudan Savanna ecological zone of Nigeria, during 2001/02 and 2002/03 dry seasons to evaluate the performance of some improved heat tolerant wheat varieties. The treatment consisted of thirteen wheat varieties laid out in randomized complete block design with three replications. The results indicated that most varieties exhibited similar characters examined while for few others they exhibited superior characters. Linfen, Gen/Rabe and Trigo produced significantly taller plants while Seri/Buc/weaver/PFau had the shortest height. Similarly Linfen had the highest number of spikelets/spike. All the varieties produced statistically similar number of tillers/plant, except Seri/Buc/weaver/PFau. Ster//TR had the longest spikes and highest number of grains/spike. Variety SeriM82 recorded the heaviest 1000-weight while Seri/Buc/weaver/PFau had the lightest grains. The results further revealed that varieties CNDO and Ster//TR had superior grain yield compared to the other varieties.
