*The study was conducted over three summer seasons in 2016, 2017, and 2018. F1 seeds from six crosses were obtained through crossing in 2016 meanwhile, F1 seeds were grown in 2017 to produce F2 seeds in 2018. The mean and range of the tested parents' scores, as well as statistics from the three growing seasons.
