Abstract: Despite their economic relevance, studies on the physical, chemical, and sensory traits of green corn are still scarce. Therefore, this work aimed to identify superior hybrid combinations for post-harvest traits. For this purpose, 36 genotypes were evaluated in two different seasons, including 34 experimental hybrids and 2 testers (AG1051 and FT2015). AG1051 is a double hybrid of green corn, and FT2015 is a single hybrid of sweet corn. pH and °Brix in raw and cooked grains and weight loss were evaluated. It is concluded that there are promising crosses for the evaluated post-harvest traits. The crosses L111 x FT2015 and L33 x FT2015 showed high °Brix values in raw (means of 9.83 and 7.00) and cooked (means of 8.08 and 7.08) grains, low pH values in raw (means of 7.21 and 7.29) and cooked (means of 7.04 and 7.22) grains, and low weight loss (means of 1.66 g and 1.49 g).
