Abstract

Common bean (Phaseolus vulgaris L; 2n=22) is the most important food legume rich in protein, minerals, and vitamins where its protein content is cheap and easily affordable for the famers of the country. The crop plays great role in maintaining the fertility of the soil through fixing atmospheric nitrogen and thus keeping diversity and stability of the agricultural system. Due to its importance, the total area allocated for common bean crop production and the yield obtained in Ethiopia is 357,299.89 ha and 540,238.94 tons respectively. The productivity of white and red common bean is 1.41 ton/ha and 1.59 ton/ha respectively in 2016 planting season. Since 1970s common bean improvement has been started in Ethiopia and since then more than 50 common bean varieties for different traits and for different agro ecologies were released through conventional breeding in Ethiopia. Currently, in common bean breeding; gene pyramiding against common bean diseases like ALS (Angular Leaf Spot), CBB (Common Bean Blight) and anthracnose and diversity assessment for diseases like CBB and ALS has been started using MAS (Marker Assisted Selection) in Southern Agricultural Research Institute at Hawassa. Therefore the aim of this article is to review common bean improvement status and to indicate some improvement gaps in Ethiopia.
菜豆改良现状(Phaseolus vulgaris L.)在埃塞俄比亚
菜豆(Phaseolus vulgaris L;豆类是最重要的食物,富含蛋白质、矿物质和维生素,其蛋白质含量便宜,对该国的农民来说很容易负担得起。作物通过固定大气氮来维持土壤肥力,从而保持农业系统的多样性和稳定性。由于其重要性,埃塞俄比亚分配用于普通豆作物生产的总面积和产量分别为357,299.89公顷和540,238.94吨。2016年种植季白豆和红豆产量分别为1.41吨/公顷和1.59吨/公顷。自20世纪70年代以来,埃塞俄比亚开始进行普通豆改良,此后通过常规育种在埃塞俄比亚发布了50多个具有不同性状和不同农业生态的普通豆品种。目前,在普通豆类育种中;阿瓦萨南方农业研究所利用MAS (Marker Assisted Selection)技术开展了针对ALS (Angular Leaf Spot)、CBB (common bean Blight)和炭疽病等常见豆类疾病的基因金字塔构建和CBB和ALS等疾病的多样性评估。因此,本文的目的是回顾普通豆的改善状况,并指出一些改进差距在埃塞俄比亚。
