Orphan crops are crops that are of substantial importance to food security and economic growth at a local or regional scale, yet lacking investment in crop improvement and seed systems development. Tef is an example of such an orphan crop. It is vital to economy and food systems in the Horn of Africa, yet investment in breeding and agronomy is very limited. Since almost 20 years, the Syngenta Foundation for Sustainable Agriculture has invested in tef, supporting work to both develop and disseminate improved varieties to farmers in Ethiopia. To date, this has led to the release of four improved varieties. As the project also invested in the development of seed systems for improved tef varieties, it allowed us to monitor seed production and variety adoption over time. The data obtained from seed production monitoring over 7 years and 4 varieties from both formal and informal seed systems shows a total of 1227 tons of tef seed from improved varieties delivered to farmers in Ethiopia. Assuming an average genetic gain of 0.4 tons per hectare, this suggests that the value generated to farmers and local value chains from tef breeding and seed systems development exceeds the investment by an order of at least 2.5. With this paper, we want to make a case for more long-term investment in breeding and seed systems development and stimulate replication of the approach to other orphan crops. We further want to call for a continued investment in tef crop improvement and seed systems development.
小众作物是指那些在地方或区域层面上对粮食安全和经济增长具有重大意义,但在作物改良和种子系统开发方面缺乏投资的作物。画眉草就是这样一种小众作物。它对非洲之角的经济和粮食系统至关重要,但在育种和农艺学方面的投资非常有限。近20年来,先正达可持续农业基金会一直投资于画眉草,支持开展相关工作,向埃塞俄比亚的农民开发和推广改良品种。迄今为止,这已培育出四个改良品种。由于该项目还投资于改良画眉草品种的种子系统开发,因此我们能够长期监测种子生产和品种采用情况。从7年期间对4个品种的正式和非正式种子系统的种子生产监测中获得的数据显示,共有1227吨改良品种的画眉草种子交付给了埃塞俄比亚的农民。假设每公顷平均遗传增益为0.4吨,这表明画眉草育种和种子系统开发为农民和当地价值链带来的价值超过投资至少2.5倍。通过本文,我们希望呼吁对育种和种子系统开发进行更多长期投资,并推动将这种方法推广到其他小众作物。我们还希望呼吁继续投资于画眉草作物改良和种子系统开发。
