Different letters indicate significant differences among treatments and genotypes based on Tukey’s HSD test (P ≤ 0.05) within a trait. Values are least-square means ± standard errors of six replicates for 2018 and 15 replicates for 2019. Control plants showed no wilting and therefore scored zero and were not analyzed.
