Abstract

Most African crop breeding programs conduct early-stage selection at very few research stations, which may not reflect smallholder farm conditions. Early-stage on-farm sparse testing utilizes genomic relationships to shift selection from research stations to hundreds of farms in the target population of environments, facilitating increased genetic gain in farmers' fields.

摘要

大多数非洲作物育种项目仅在极少数研究站进行早期选择，这可能无法反映小农户的农场条件。早期田间稀疏测试利用基因组关系将选择从研究站转移到目标环境群体中的数百个农场，从而有助于在农民田间提高遗传增益。
