Public-private partnerships (PPPs) are globally recognized for their potential to accelerate genetic improvement and delivery of new high-yielding seed varieties in developing countries. However, despite the strong advocacy for PPPs in crop improvement, there is little empirical evidence about their performance, capacities, and contribution to the development of seed industries and the promotion of competitive seed markets. This paper uses the experience of the MasAgro maize consortium, a PPP in Mexico, to examine crop variety innovation and delivery through PPPs, assess PPPs' capacities to commercialize public germplasm-based varieties, and derive lessons for the design and implementation of future PPPs. Drawing on a combination of multiple data sources, we examined the PPP's performance in the generation, dissemination, and commercialization of new maize hybrids. Our examination over the period 2011-2019 shows that the consortium was successful in maintaining a substantial flow of agronomically competitive maize hybrids, which compared favourably with the number of new varieties generated by national and international seed companies and the public sector. The partnership also contributed to refreshing and rejuvenating the variety portfolios of the consortium companies, which appear to have succeeded in bringing MasAgro varieties quickly into the market. However, seed sales achieved by MasAgro hybrids over this period remained small and multinational companies consistently maintained their leadership in the maize seed market. Our analysis shows that PPPs have strong capacities for the development of competitive seed varieties, but they face significant challenges in scaling up the uptake and adoption of these innovations in highly concentrated markets. To succeed in their objective of delivering affordable, high-quality seed on a large scale to smallholder farmers in developing countries, PPPs need to urgently incorporate a commercial and market-oriented perspective along all steps of the plant breeding and dissemination process.
公私伙伴关系(PPPs)在全球范围内因其有潜力加速发展中国家的遗传改良以及新高产种子品种的推广而受到认可。然而,尽管在作物改良方面对公私伙伴关系大力倡导,但关于其表现、能力以及对种子产业发展和竞争性种子市场促进的贡献,实证证据却很少。本文利用墨西哥的一个公私伙伴关系项目——MasAgro玉米联盟的经验,来研究通过公私伙伴关系进行的作物品种创新与推广,评估公私伙伴关系将基于公共种质的品种商业化的能力,并为未来公私伙伴关系的设计与实施吸取经验教训。借助多种数据源的组合,我们考察了该公私伙伴关系在新玉米杂交品种的培育、传播和商业化方面的表现。我们对2011 - 2019年期间的考察表明,该联盟成功地保持了大量具有农艺竞争力的玉米杂交品种的产出,与国家和国际种子公司以及公共部门培育的新品种数量相比具有优势。这种伙伴关系还为联盟公司的品种组合更新和焕发生机做出了贡献,这些公司似乎成功地将MasAgro品种迅速推向了市场。然而,在此期间MasAgro杂交品种的种子销售规模仍然较小,跨国公司在玉米种子市场上始终保持领先地位。我们的分析表明,公私伙伴关系在培育有竞争力的种子品种方面有很强的能力,但在高度集中的市场中扩大这些创新成果的采用和推广方面面临重大挑战。为了成功实现向发展中国家的小农户大规模提供价格合理、质量上乘种子的目标,公私伙伴关系需要在植物育种和传播过程的所有环节中紧急纳入商业和市场导向的视角。
