Public breeding programs are pushing to implement demand-led breeding to increase variety adoption, while tackling multiple challenges for increased production under climate change. This has included the improvement of variety target product profiles involving multiple stakeholders. A special case involves the unexpected and rapid spread of the Shangi potato variety in Kenya. This variety was not an especially outstanding variety and the levels of its traits did not exceed the expected thresholds defined in the target product profile for table potato in East Africa. By examining the customer segments looking at gender but also social contexts of smallholder and disadvantaged farmers such as access to markets, inputs, and labor, it became apparent that ready availability of potatoes for consumption, processing, or planting was of prime importance. Given the storage and market constraints, Shangi's very short dormancy, which had been assumed to be a negative trait for farmers, women cottage processors and consumers, was actually meeting the needs for available product and planting material. Consequently, this provided these groups increased control over their productive activities. The case study presented here analyzes different components of potato variety change in Kenya. It explores the challenges and tradeoffs faced by public sector breeding programs and how gender analysis from a broader inclusion perspective can uncover the underlying causes of varietal adoption. Focusing on the Shangi potato variety, the case study reveals a series of lessons learned that have re-shaped the definition of breeding priorities.
公共育种计划正在推动实施需求导向型育种,以提高品种的采用率,同时应对气候变化下增加产量的多重挑战。这包括改进涉及多个利益相关者的品种目标产品概况。一个特殊案例是尚吉马铃薯品种在肯尼亚意外且迅速地传播。该品种并非特别出众,其性状水平未超过东非鲜食马铃薯目标产品概况中规定的预期阈值。通过研究不同客户群体,不仅考虑性别因素,还考虑小农户和处境不利农民的社会背景,如市场准入、投入和劳动力情况,很明显,随时可获得用于消费、加工或种植的马铃薯至关重要。鉴于储存和市场限制,尚吉马铃薯极短的休眠期,原本被认为对农民、女性家庭加工者和消费者是个不利性状,实际上却满足了对可获得产品和种植材料的需求。因此,这使这些群体对其生产活动有了更大的掌控权。此处呈现的案例研究分析了肯尼亚马铃薯品种变化的不同组成部分。它探讨了公共部门育种计划面临的挑战和权衡,以及从更广泛的包容性视角进行性别分析如何能揭示品种采用的根本原因。以尚吉马铃薯品种为重点,该案例研究揭示了一系列经验教训,这些经验教训重塑了育种优先事项的定义。
