Abstract

Aim: The main objective of the study was to evaluate and recommend high yielding varieties thus enabling farmers to assess the performance of improved varieties of their choice through participatory variety selection approach.

Materials and Methods: The study contained two improved highland maize varieties and two mid altitude local checks. The trial was laid out in a single plot of 10m*10m plot size with no replications at five locations. Intra and inter spacing was 25cm*75 cm , respectively.

Results: The highest combined yield was obtained from BH661 (6170.67kg/ha) followed by Jibat (6109.33 kg/ha) and BH660 (4946.67 kg/ha). The lowest yield was obtained from Kolba (4602.67 kg/ha). At Giraram, Generally, the highest total score was given to BH661 (12) followed by Jibat (9) and kolba (3), respectively. At Misleawash, Generally, the highest total score was given to Kolba (15) followed by Jibat (7) and BH661 (2), respectively.

Conclusion: It was concluded that BH661 and Jibat varieties could be the potential varieties in current use. This study has suggested that introduction, collection and extensive hybridization of maize in Ethiopia is a crucial task to enhance genetic variability and thereby to increase the chance for selecting and developing high yielding genotypes and hybrids through participatory approach.
