Markers significantly associated with grain yield in the Stage 2 (S2) yield trials evaluated in the late-heat (S2 late-heat), moderate-drought (S2 mod-drought) and severe-drought (S2 sev-drought) environments at Obregon (Mexico), during the 2013–2014 (1314), 2014–2015 (1415), 2015–2016 (1516), 2016–2017 (1617), 2017–2018 (1718) and 2018–2019 (1819) crop cycles and in the combined (com.) analysis across crop cycles. The chromosomes are shown in the x-axis and the − log₁₀ p values in the y-axis. The threshold lines correspond to the threshold using the Bonferroni correction for multiple testing at an α level of 0.20.
