Inter-plot competition in hybrid maize multi-environment yield trials in Ethiopia can reduce rate of genetic gain
Friday, 12-06-2026 | 08:38
Conducting large-scale multi-environment trials (METs) is practically challenging to breeding programs in Sub-Saharan Africa due to limitations of land, seed, and associated costs of phenotyping. As a result, early-generation hybrid maize trials are usually planted in single-row plots. In trials with single-row plots, genotypes compete with their neighbors for resources, and this biases the prediction of the genotype value.

Agricultural biotechnology holds immense potential to foster sustainable agriculture, but transforming lab breakthroughs into real-world solutions requires a seamless blend of robust R&D, science-based regulations, and effective communication. To ensure society reaps these benefits while minimizing risks, scientists, regulators, and policymakers must collaborate closely so that scientific advancements and regulatory practices evolve hand in hand.

Canada Clears Gene-Edited High-GABA Tomato as Safe Non-Novel Food
Japanese biotechnology firm Sanatech Life Science Co., Ltd. has secured regulatory clearance in Canada for its gene-edited Sicilian Rouge High GABA tomato. Following a thorough review by Health Canada's Novel Foods Section, the federal agency determined that the product meets all requirements under its plant breeding guidelines and does not meet the definition of a novel food.
