On-farm trials were conducted in the year 2000/2001 in the major maize growing areas, namely Bako, Pawe, Awasa, Jima, Alemaya, Melkassa and Ambo for the evaluation of the performance of four promising QPM varieties under farmers' conditions against the previously released normal maize hybrid, BH-540. The design used was a randomized complete block design (RCBD) using each farmer's field as a replication. Participatory evaluation methodology was also used to acquaint the farming communities and the extension workers with the QPM varieties and to facilitate effective dissemination of farmer-preferred QPM varieties in the future. Results revealed that the performance of the varieties varied significantly across locations. Analysis also showed that there were significant yield differences among the varieties tested at Bako and Awasa (p<0.01) and at Ambo (p<0.10). In Ambo and Awasa areas (high altitude areas), all the QPM varieties gave significantly lower yields than the check while in Bako (mid-altitude areas), the QPM variety (CML-144 x CML-159) x CML-176 gave significantly higher yield than other varieties including the local check. Besides, farmers' assessment revealed that they were interested in this QPM variety because of its higher grain yield, nutritional value and moderate tolerance against the major diseases such as Gray Leaf Spot (GLS) and Turcicum Leaf Blight (TLB). Hence, the QPM variety, (CML-144 x CML-159) x CML-176, which showed moderate tolerance against the major diseases and gave comparable yields to the check was recommended for possible release especially for the mid- and low altitude areas (1000-1800 masl) of Ethiopia.Collection: CIMMYT Staff Publications Collection
