Initially, breeders used landraces to create varieties whose seed, freely distributed through an international testing network, could be saved by farmers. A second phase in which CIMMYT forged partnerships with local and regional seed companies reflected the shift toward “market-led development.” This moderated free access to seed and fostered a gradual switch to hybrid technology. A trend among donors towards increased accountability and shorter funding cycles concurrently restricted CIMMYT’s investment in long-run research goals and accelerated a change of focus to Africa. Nonetheless, the development of germplasm tolerating drought and low soil fertility continued for decades, with eventual payoffs. Meanwhile, a long-running program to improve protein nutrition through high lysine maize varieties stalled due to lack of demand. In the twenty-first century, partnerships with global private seed companies allowed access to new technologies such as advanced screening methods, genomic selection, doubled haploids and gene editing T2 - Agricultural Science as International Development: Historical Perspectives on the CGIAR Era ER -
