尽管埃塞俄比亚马铃薯计划已经发布了30多个新品种，主要是根据产量潜力和对晚疫病的耐受性而选择的，但大多数农民仍然选择种植较老的当地品种。认识到这一点，目前的研究旨在确定农民在决定种植哪些品种时认为最重要的特征。这项研究是在埃塞俄比亚西北部的两个地点进行的，代表两个主要的农业生态区，在两个不同的生长季节，采用参与性品种选择方法。种植了9个地方品种和3个新品种的无病种薯。23个性状被发现会影响农民选择的品种，其中7个在农业生态区之间存在差异。在Laigaint（亚湿润凉爽农业生态学）的23个性状中，也观察到了3个性状的性别差异。在23个性状中，有12个被认为在一个或两个农业生态区以及至少一个生长季节中非常重要。目前，这12个性状中有8个在埃塞俄比亚马铃薯品种选择计划中没有得到高度重视。结果表明，农民的选择标准是非常多样的，没有一个品种具有所有理想的特性，并有必要选择适合不同的农业生态和生长季节的品种。这项研究进一步表明，考虑到农民的利益是重要的高度杂合，克隆繁殖作物，如马铃薯被农民接受。
Although the Ethiopian potato program has released more than 30 new varieties, selected primarily for yield potential and late blight tolerance, the majority of farmers still choose to grow older local varieties'. Cognizant of this, the current study aimed to identify traits that farmers consider most important when deciding which varieties to grow. The study was conducted at two sites in northwest Ethiopia, representing two major agroecological zones, in two distinct growing seasons, using a participatory variety selection approach. Disease-free seed tubers of nine local and three new varieties were planted. Twenty-three traits were found to influence the varieties that farmers selected and seven of them differed between agroecological zones. Gender differences were also observed for three of the 23 traits at Laigaint (submoist cool agroecology). Of the 23 traits, 12 were considered very important in one or both of the agroecological zones as well as in at least one growing season. At present eight of these 12 traits are not given high priority by the Ethiopian potato variety selection program. The results show that farmers' selection criteria are very diverse, that no variety possesses all desirable characteristics, and that there is a need for selecting varieties adapted to different agroecologies and growing seasons. This study further suggests that taking farmer interests into account is important for a highly heterozygous, clonally-propagated crop like potato to be accepted by farmers.
