Maize under heat stress in lowland tropics: Learnings and the way forward por Fatma, Sara, Singh, Hema, Singh, Pawan, Vinayan, Madhumal Thayil, Zaidi, Pervez H.

“…Therefore, diving deeper and exploring local landraces and wild accessions is necessary to explore wider genotypic variation for heat stress tolerance in tropical maize. Recent advances in genomics-assisted breeding may help identify genomic regions associated with heat stress tolerance in maize and target the introgression of validated genomic regions into elite maize germplasm to develop the next generation of maize cultivars with improved, stable performance under heat stress conditions. …”
