Abstract
Description
Early and ultra early ripening tomato lines are compared. By having tomato vines that are capable of ripening in cooler or colder environments, it allows for tomatoes being grown in more regions in the US and Canada. In this study, early and ultra early tomatoes were crossed in a greenhouse. Crossed plants were transplanted outside early June. Weeding was done by hand. Irrigation as needed. Nitrogen and phosphorus were administered. Fruit size was increased in all F1 hybrids. The yields on F1 hybrids varied.
