Farmers' innovation and selection of barley varieties were studied in the Tigray Region in northern Ethiopia. Two districts each in the central and southern zones and three districts in the eastern zone of Tigray were randomly selected for this study, which sought to understand the current status of local barley varieties and to measure their relative preference by farmers. Household surveys were conducted covering 240 households to elicit farmers' views on the values, constraints, and opportunities of growing local varieties of barley. This was supported by focus-group and informal discussions with elders, key informants, and women's groups. Case studies were made of local farmers whom the community recognized as barley breeders. Twenty-four barley varieties and their major descriptors were recorded. Seed and varietal-selection criteria depended on the environmental and varietal characteristics. Investigation of intrahousehold decision making indicated that, while men tended to decide on the type of variety to grow, seed storage and processing were exclusively the responsibility of women. Farmers undertook preharvest and postharvest selection, giving emphasis mainly to earliness and spike characteristics. The distinct varietal-selection and seed-renewal procedures revealed their potential for use in further plant breeding. The case-study analysis of farmer-developed varieties provided knowledge that, if combined with scientists' knowledge, could lead to identification and development of valuable cultivars with a wide potential for use in semiarid areas of Tigray and other parts of Ethiopia.
在埃塞俄比亚北部的提格雷地区,对农民的大麦品种创新与选择进行了研究。从提格雷中部和南部地区各随机选取两个区,从东部地区随机选取三个区开展此项研究,旨在了解当地大麦品种的现状,并衡量农民对它们的相对偏好。开展了涵盖240户家庭的住户调查,以了解农民对种植当地大麦品种的价值、制约因素和机遇的看法。与长者、关键信息提供者及妇女团体进行的焦点小组讨论和非正式讨论为此提供了支持。对被社区认可为大麦育种者的当地农民进行了案例研究。记录了24个大麦品种及其主要特征。种子和品种选择标准取决于环境和品种特性。家庭内部决策调查表明,虽然男性倾向于决定种植的品种类型,但种子储存和加工完全由女性负责。农民在收获前和收获后进行选择,主要侧重于早熟性和穗部特征。独特的品种选择和种子更新程序显示出它们在进一步植物育种中的应用潜力。对农民培育品种的案例研究分析提供的知识,若与科学家的知识相结合,可能会促成在提格雷半干旱地区及埃塞俄比亚其他地区广泛应用的有价值品种的识别与培育。
