Growing vegetables in a greenhouse provides an extra bounty. The tomato has been a greenhouse favorite for over 100 years, according to Bob Anderson of the University of Kentucky. There are varieties of tomatoes grown with the ability to resist the higher likelihood of disease. These make excellent choices for growers no matter how big or small the setup is inside.

Wilt, Leaf Mold, Mosaic Virus Resistant

Greenhouse environments must be carefully regulated to avoid disease and injury to the plants. However, regardless of how strict you are with humidity and water controls, the greenhouse is a very high temperature and humidity environment. That is both its good and bad point. That environment allows strong growth at all times of the year, regardless of what the outdoor climate is. While many tomato varieties will grow in a greenhouse, only two are resistant to the most common greenhouse diseases: Caruso and trust.

Powdery Mildew Resistant

If your greenhouse has a problem with powdery mildew and you prefer a variety that will grow unaffected by it, there are special greenhouse varieties that work well. These are the DRW 4369 (Belliro) and DRW 4409.

Leaf Mold Resistant Only

Leaf mold shows up as a powdery white spot or spots on the underside of the leaves on the tomato plant. While leaf mold is seen in outdoor gardens, it typically is a greenhouse disease specifically and taken to fields by plants from inside. Resistant varieties are buffalo, capello, jumbo, dombito, pink KR15 and CR-864, match, ultra sweet, ultra pink, furon and vision.

Tobacco Mosaic Virus Resistant Only

The variety called Boa is developed to be resistant to the tobacco mosaic virus specifically. It isn't resistant to any other of the common tomato diseases, but luckily, TMV doesn't readily mix with the other diseases either. So if you have a problem with this virus, you probably aren't seeing the others.

Fusarium Crown and Root Rot Resistant

Trust is the only variety of greenhouse tomato resistant to fusarium crown and the even more prevalent root rot. Root rot is common in any tomato garden setting, but high humidity greenhouse tomatoes are even more susceptible. The trust variety is a very resistant strain that resists wilt, leaf mold and the tobacco mosaic virus, too.

Common

Don't think you must buy greenhouse specialty seeds or seedlings to have success with tomatoes. Most common plants such as Beefsteak varieties Better Boy, Celebrity, First Lady, Solar Set and Sunbeam will do fine. Cluster types of tomatoes are popular with greenhouse growers also, because they can grow up a trellis and take up less floor space per plant. They produce a heavy, meaty tomato much like the Beefsteak varieties.

Selection

All plants produce differently in different settings. When you choose what varieties to plant in your greenhouse, keep an accurate record of the amount of fruit each plant produces. Weigh tomatoes and write down how many pounds you harvest at each picking, and add them up at the end of the plant's life. When you find a variety is underperforming, select another to take its place. A break-even weight of produce per plant is four to five pounds per year. Less than that and you need to look for another variety; even with that and you can decide to keep trying or change the plant.
