Maize is affected by various diseases, but among these, maydis leaf blight (MLB) is one of the most serious diseases. The disease is caused by <i>Cochliobolus heterostrophus</i> and is responsible for yield losses up to 40%. When developing cultivars for a specific ecology, days to flowering and maturity are important breeding traits to consider. Thus, understanding the genetic basis of MLB resistance, specifically the "O" race of the pathogen, and maturity-related traits is crucial to develop climate-resilient maize hybrids. This study aimed to determine the gene actions and their interactions for MLB resistance and maturity-related traits using a sixFrontiers in plant science1551940https://www.ebi.ac.uk/biostudies/studies/S-EPMC11979256biostudies-literatureUnderstanding the genetic basis of resistance to maydis leaf blight and maturity-related traits in corn.PMC11979256Sarkar DBagaria PKJat BSKumar PNath CPiyal PKumar SRakshit SAggarwal SKYankanchi SSingh SBSingh RJat HSKumar BPushpendrafalseUnderstanding the genetic basis of resistance to maydis leaf blight and maturity-related traits in corn.Maize is one of the most versatile and commercially produced crops used for food, feed, fodder, ethanol, oil, and industrial raw materials.
