Early generation seed (EGS) production and delivery pathways are critical components of so-called formal seed systems, of principal importance in the release of improved varieties into national seed systems. Vegetatively propagated crops (VPCs), with clonal reproductive ability and considerable differences in production and dissemination patterns from sexually propagated crops, often challenge generalized assumptions about ‘business models’ for private sector-led EGS production.

早期种子生产的公共和私人机构安排：东南亚的木薯种子价值链


早期种子 （EGS） 生产和交付途径是所谓的正规种子系统的关键组成部分，在将改良品种释放到国家种子系统中具有主要重要意义。无性繁殖作物 （VPC） 具有克隆繁殖能力，并且在生产和传播模式上与有性繁殖作物存在很大差异，经常挑战关于私营部门主导的 EGS 生产“商业模式”的一般假设。
