Abstract Participatory variety selection (PVS) trials were conducted in 2012 and 2013 in Chilga district of North West
Ethiopia to evaluate the performance of improved maize (Zea mayz L.) varieties and to assess farmers’ criteria for maize
variety selection for future maize improvement. Six improved varieties including the local check were used for the study at
four farmer villages: Anguaba, Serako and Eyaho. The experiment was laid out in a randomized complete block design and
the trials were replicated over farmers’ field in the three villages. The results of analysis revealed that a significant difference
among the varieties for most the agronomic traits recorded except for grain yield which was not significant. With regard to
location, no significant difference was observed for the majority of the traits except plant height and ear height indicating
similarity in agro ecologies of the three villages. The results also revealed that farmers’ preferences in some cases coincide
with the researchers’ selection. However, in general farmers have shown their own way of selecting a variety for their
localities. These parameters include earliness, drought tolerance, grain yield, vigorousity, husk cover, cob size, grain color
and grain size. Hence, it is a paramount important to include farmers’ preferences in a variety selection process. Therefore,
based on objectively measured traits, farmers’ preferences and the agro ecologies of the site the varieties BH-540 and
BHQPY-545 are recommended in the study area. The variety BHQPY-545 should be given high attention by the responsible
body since it has quality protein content besides having favored traits in the study area.

1. Introduction
Maize (Zea mays L) is one of the worlds’ three primary
cereal crops. It occupies an important position in world
economy and trade as a food, feed and industrial grain crop.
Maize holds a unique position in world agriculture as a food,
feed for livestock and as a source of diverse, industrially
important products. It accounts for 15-56% of the total daily
calories of people in developing countries, and is currently
produced on nearly 100 million hectares in 125 developing
countries and is among the three most widely grown crops in
75 of those countries (FAOSTAT, 2010).
Maize is the most important food security crop for
Ethiopia, as it is for many other countries in sub-Saharan
Africa. The average annual rate of growth in area and yield
has been increasing over the last four decades (FAOSTAT,
2008). Maize is one of the most important cereal crops in
Ethiopia, ranking second in area coverage after teff and first
in total production (CSA, 2013).
Varietal selections in maize in Ethiopian have usually
been dominantly based on grain yield. Large numbers of

breeding lines have been developed at various research
stations and their performance evaluated across
multi-location tests over several years and only a few
varieties are so far identified. Varietal evaluation and
decisions were only by researchers; however, this did not
lead to the expected speed of variety release, or their
dissemination afterwards. In addition, in developing new
materials and extending them to farmers, classical plant
breeding faces two major obstacles. First, new varieties can
be disappointing to farmers where undesirable traits go
undetected during the breeding process. Secondly, breeders
necessarily discard many crosses and varieties during the
selection process because of traits considered undesirable;
however, these traits may actually be of interest to farmers.
These illustrate the communication gap between researchers
and farmers.
The importance and complex nature of agricultural
research demands coordinated effort among biological
scientists, extension agents and farmers in order to ensure
that appropriate technology is developed and promoted (Rao
et al., 2004).
Participatory plant breeding/selection has shown success
in identifying more number of preferred varieties by farmers
in shorter time (than the conventional system), in
accelerating their dissemination and increasing cultivar
diversity (Weltzien, E. et al., 2003). Therefore, adding
