  • Phenomic and genomic approaches are required to evaluate the progress of breeding strategies. Here, the authors analyse 65 years of genetic progress in maize, showing that breeders have selected traits with stable effects on yield whereas not for adaptive traits key for climate change adaptation.

  • Breeding has increased crop productivity, but whether it has also changed phenotypic plasticity is unclear. Here, the authors find maize genomic regions selected for high productivity show reduced contribution to genotype by environment variation and provide evidence for regulatory control of phenotypic stability.

  • Peter Balint-Kurti, Qin Yang and colleagues report that ZmCCoAOMT2, which encodes a caffeoyl-CoA O-methyltransferase, is a gene within the quantitative trait locus qMdr9.02, which confers resistance to southern leaf blight and gray leaf spot. Their findings suggest that resistance might be caused by differences in levels of lignin and other metabolites in the phenylpropanoid pathway.

  • James Holland and colleagues report a genome-wide association study for resistance to Southern Leaf Blight (SLB) in the maize nested association mapping population. Linkage mapping identified 32 QTLs linked to SLB resistance, and association tests showed that 51 SNPs, many located within the QTL intervals, are significantly associated with SLB resistance.

  • Disease-resistant crops have the potential to reduce crop losses. This Review discusses how advances in genetic and genomic technologies are contributing to efforts by plant breeders to generate durable, broad-spectrum disease resistance in crop plants.
