Bean Enhance

普通豆（Phaseolus vulgaris）是东非和中非（ECA）生产的主要豆类作物，为数百万小农提供重要的营养和收入来源。不幸的是，普通豆类的产量会受到一系列生物和非生物因素的负面影响。角斑叶斑病（ALS），由真菌病原体灰树斑伪cercospora grisiseola引起，是非洲种植区产量损失的主要原因，该疾病的爆发可导致种植者及其家庭营养和经济贫困。Bean Enhance是一个转化研究项目，它将利用乌干达已建立的普通豆类角叶斑病病原体的病理基因组学资源，将它们与ciat -乌干达正在进行的抗病育种项目结合起来，并扩大它们，以便当地的植物病理学家能够监测坦桑尼亚和乌干达分离株的运动。并使植物育种者能够测试对主要抗性来源的反应，以便在未来部署与区域相关或更持久的品种。这将使重要的ALS分离株能够被有效地追踪，使种植者能够做出更好的品种选择，以避免疾病造成的损失。通过增加小农收入和在农业轮作中推广豆类作为可持续作物，减少疾病将有效地促进坦桑尼亚和乌干达的社会经济稳定。该项目还将通过在坦桑尼亚和乌干达举办一系列讲习班，培训种子生产管道中的关键行动者，制定有效的测试和认证程序，向普通豆类生产者提供无病基本种子；这将包括种植者/生产者团体、种子生产行业、推广服务和政府的成员，以确保知识能够传播给最大的相关受众，并转化为实现最大的影响。

Common bean (Phaseolus vulgaris) is the major legume crop produced in East and Central Africa (ECA) providing a vital source of nutrition and income to millions of small-holder farmers. Unfortunately common bean productivity can be influenced negatively by a range of biotic and abiotic factors. Angular leafspot (ALS), caused by the fungal pathogen Pseudocercospora griseola is a primary cause of yield losses in ECA and outbreaks of the disease can result in nutritional and financial poverty for growers and their families. Bean Enhance is a translational research project that will exploit established Ugandan pathogenomics resources for the common bean angular leafspot pathogen, aligning them with ongoing disease resistance breeding programmes at CIAT-Uganda and expanding them so local plant pathologists can monitor the movement of isolates in Tanzania as well as Uganda, and to enable plant breeders to test the response to key sources of resistance in order to deploy regionally relevant or more durable varieties in the future. This will allow important ALS isolates to be tracked effectively, allowing growers to make better variety choices to avoid losses to disease. Reductions in disease will contribute effectively to improve socio-economic stability in Tanzania and Uganda by increasing small-holder incomes, and through promoting legumes as a sustainable crop in agricultural rotations. The project will also develop effective testing and certification procedures for supplying disease-free basic seed to common bean producers through implementing a series of workshops in Tanzania and Uganda to train key actors in the seed production pipeline; this will include members of grower/producer groups, the seed production industry, extensions services and the government to ensure knowledge can be disseminated to the greatest relevant audience and translated to achieve the greatest impact possible.
