FLORIDA MH-1 is the first fresh-market tomato variety developed for machine
harvest in Florida. It was widely tested in the state as a breeding line with
the designation MH-1 and in the Southern Tomato Exchange Program as STEP 599.
FLORIDA 141M-1 was produced by crossing the variety WALTER with the breeding line
Heinz 3, then selecting in the early generations for desirable fruit and vine
type and disease resistance.

The most outstanding characteristic of FLORIDA M14-1 is that it can be harvested
mechanically. The fruit separate from the vines free of stems pointlesss) be-
cause of the expression of the j2 gene. Without the jointless character it
would not be economically feasible to consider machine harvesting of fresh
market tomatoes in Florida. FLORIDA MH-1 fruit are very firm, another character
necessary for machine harvest. Red ripe fruit are probably firm enough to be
harvested and marketed successfully. Other desirable characters include smooth,
crack-free fruit, excellent fruit ripening from mature green to pink and ripe,
excellent internal and external fruit color and concentrated fruit set.

FLORIDA 11II-1 represents a significant advancement in the development of multiple
disease-resistant tomato varieties. FLORIDA IMH-1 is resistant to most of the
major diseases and possesses more disease resistance genes than any previous
variety (Table 1). FLORIDA MH-1 is resistant to at least 19 diseases (Table 1)
and has at least 34 disease resistance genes. Tomato growers can economically
utilize these disease resistances by tailoring disease control programs to fit
the variety.

No other fresh-market variety approaches FLORIDA M--1 in yield when machine
harvested, and when harvested by hand it yields as well as or better than Walter
and Homestead. Fruit ripen uniformly, lacking the dark green shoulder, and are
similar in size to Walter. The fruit shape is a deep globe and the stylar ends

are very smooth. The only fruit defect is the tendency for the shoulders to be
slightly ridged under some growing conditions. The fruit ripen to a full red
color from mature green with and without ethylene gassing.

The vine of FLORIDA MH-1 is determinate and pruning is not necessary for machine
harvest. If grown for hand harvest fruit size can be increased by light pruning.
FLORIDA MH-1 is similar in maturity to Walter, however, the maximum number of
harvests would be three and most fruit can be picked with one harvest.
