I saw plants of an F2 of Kumato in a grower field several years ago and did not see a lot of variability in fruit or plant characteristics. For some hybrids, parent lines are similar in traits or may even be closely related genetically (even sister lines) with one having one or more dominant resistance genes crossed with a similar line that has other dominant resistance genes so the hybrid turns out to have multiple disease resistances with the dominant genes being heterozygous.
