This study evaluates spring wheat varieties for yield in twelve locations of the semi-arid zone, Nigeria. Treatments were laid out in a randomized complete block design with three replications. The results indicate that mean flowering dates across location were 61, 68, 62, 57 and 70 DAS for Kirenowa, Jigawa. Kano. Sokoto and Kadawa respectively. Grain yield, show that there was no significant difference among the wheat lines tested in all locations except Jigawa. The genotype Kauz*2/Bows/Kauz and Kauz/Bow/mkt are very promising heat tolerant materials across the wheat growing zone. These two varieties are therefore recommended for further testing on-farm trial.
