characteristics important to the Rutgers breeding program. Because of the large number of seedlings, the initial spacing was restricted to less than 1 m between each plant in the row. Each year, poor-performing trees were systematically culled with many others

program Structure indicated two populations and that the population is fragmented. However, the F IS values indicate a high inbreeding coefficient and suggest the trees are in fact breeding with closely related individuals. Therefore, we conclude that

The rootstock is an important component of a healthy and productive citrus tree, influencing the fruit yield, fruit quality, tree size, and tolerance of diseases ( Bowman and Joubert, 2020 ; Castle et al., 2011 ; McCollum and Bowman, 2017
