Farmer-participatory breeding approach is an important component in the crop improvement of lablab ( (L.) Sweet). The study was carried out to obtain the knowledge, practices and preferences of lablab through 31 lablab growing-farmers from Arusha, Kondoa, Karatu, Same and Babati districts of Tanzania toward initiating a lablab breeding program. Semi-structured questionnaires were administered and focused group discussions were held to collect data on the socio-demographic factors, production practices, constraints and farmer's preferred traits of lablab. Selection of preferred traits and accessions was also done by the farmers in the field. Results showed that the chief constraints of lablab production are pests and diseases, poor marketability, low seed quality, inadequate rainfall, expensive agrochemicals, low yield, and poor storage facilities. The major pests are pod borer (field) and bruchids (storage). Preferred traits for lablab improvement include the development of insect pests and disease-resistant varieties, early maturing, high yield, black colored seed for market, short cooking time, and dense foliage. Genotypes EK2, D360, HA4, and D96 with preferred traits were identified by farmers, which forms critical decisions in crop improvement. This study describes the current view of lablab production and generates the understanding of farmers' perceptions and preferences vital for breeding priorities and programs to increase its production, utilization and consumption.
农民参与式育种方法是蝶豆（Lablab purpureus (L.) Sweet）作物改良的重要组成部分。本研究旨在通过来自坦桑尼亚阿鲁沙、孔多阿、卡拉图、萨梅和巴巴蒂地区的31位种植蝶豆的农民，获取有关蝶豆的知识、种植实践和偏好，以启动一项蝶豆育种计划。研究人员发放了半结构化问卷，并组织了焦点小组讨论，以收集有关社会人口因素、生产实践、制约因素以及农民对蝶豆偏好性状的数据。农民们还在田间对偏好的性状和品种进行了选择。结果表明，蝶豆生产的主要制约因素包括病虫害、市场销路不佳、种子质量低、降雨不足、农用化学品价格昂贵、产量低以及储存设施差。主要害虫是豆荚螟（田间）和豆象（储存期）。蝶豆改良的偏好性状包括培育抗病虫害品种、早熟、高产、市场上受欢迎的黑色种子、烹饪时间短以及枝叶茂密。农民们确定了具有偏好性状的基因型EK2、D360、HA4和D96，这为作物改良做出了关键决策。本研究描述了当前蝶豆生产的情况，并增进了对农民认知和偏好的理解，这对于制定育种重点和计划以提高蝶豆的产量、利用率和消费量至关重要。
