Disease-Resistant Tomato Varieties: Choosing Tomatoes Resistant To Disease

Disease-Resistant Tomato Varieties: Choosing Tomatoes Resistant To Disease

By: Laura Miller

Nothing is more depressing than losing an entire crop of tomatoes. Tobacco mosaic virus, verticillium wilt and root-knot nematodes can damage and kill tomato plants. Crop rotation, garden hygiene measures and sterilizing tools can only control these problems to a limited extent. When these problems are present, the key to reducing tomato crop loss lies in selecting disease-resistant tomato plants.

Choosing Tomatoes Resistant to Disease

The production of disease-resistant tomato varieties is one of the main objectives of modern hybrid development programs. While this has been successful to some extent, no single tomato hybrid has yet been developed which is resistant to all diseases. Additionally, resistance does not mean total immunity.

Gardeners are urged to select disease-resistant tomatoes which are relevant for their gardens. If tobacco mosaic virus was an issue in past years, it only makes sense to select a variety resistant to this disease. To find disease-resistant tomato varieties, look on the plant label or seed packet for the following codes:

  • AB – Alternarium Blight
  • A or AS – Alternarium Stem Canker
  • CRR – Corky Root Rot
  • EB – Early Blight
  • F – Fusarium Wilt; FF – Fusarium races 1 & 2; FFF – races 1, 2, & 3
  • FOR – Fusarium Crown and Root Rot
  • GLS – Gray Leaf Spot
  • LB – Late Blight
  • LM – Leaf Mold
  • N – Nematodes
  • PM – Powdery Mildew
  • S – Stemphylium Gray Leaf Spot
  • T or TMV – Tobacco Mosaic Virus
  • ToMV – Tomato Mosaic Virus
  • TSWV – Tomato Spotted Wilt Virus
  • V – Verticillium Wilt Virus

Disease resistant tomatoes are what everyone hopes for when planting tis delicious vegetable. Selecting the best tomato cultivars takes more than choosing the best shape, color, and size. The most complete disease resistance package should be considered for reducing losses to diseases, as well as best results when growing.

Popular Tomatoes

Tomato plants have a growing season in the late spring and summer because the plant requires a lot of sunshine to thrive.

At the peak of the tomato growing season, the fruit produces large quantities, the fruit is less likely to be infested with nematodes, and the fruit tastes better.

Some of the most common types of tomatoes include Roma tomatoes, Heirloom tomatoes, and Cherry tomatoes. We give you an insight into different Heirloom varieties and some of the more unusual-looking tomato plants.

Two Common Types of Tomatoes

Before diving into the specific different types of tomatoes, you must first understand that tomato plants fall into two general categories: determinate and indeterminate.

Determinate tomatoes are grown on a bush and tend to stop growing when the fruit sets on the top bud.

Indeterminate tomatoes continue growing until the plant reaches almost 20 feet tall. Indeterminate plants continue to produce fruit until the first frost kills them.

All tomato types stem from these two categories. Hybrid tomatoes combine the best part of each group to form a plant that can grow in less than ideal weather conditions and is also disease resistant.

Beefsteak is One of the Most Common Types of Tomatoes

Beefsteak tomatoes are indeterminate and one of the meatiest tomato varieties. Beefsteak tomatoes are enormous and magnificent for cooking.

Of all the tomato types, beefsteak is the best for making pasta sauces and fresh dips because of the fruit’s excessive amount of juice. Beefsteak tomatoes have a mild flavor and harvest some of the largest fruit of the different varieties of tomato plants.

Often growing up to six inches in diameter, beefsteaks are excellent slicing tomatoes for sandwiches. One way to identify a beefsteak tomato is to notice the unusual ribbed shape of the large fruit.

Green Zebra is One of the Unusual Tomato Varieties

Green Zebra tomato plants may look quite distinct from conventional red tomatoes, but the taste is just as good. The tomatoes’ acidity makes the fruit is both sweet and tart and a great addition to salsa or Italian salad.

Green Zebra tomatoes are easy to locate because of their unmistakable look. The fruit is a green tomato with light green and yellow stripes. When harvesting a Green Zebra, note that the fruit is very firm compared to other tomato types.

Locating Sun Gold Tomato Types

Sun Gold is one of the common types of tomatoes and includes the popular Cherry tomato. Sun Gold tomatoes are incredibly flavorful and are best enjoyed fresh off the vine or in a garden salad.

Due to their flavor, include Sun Gold tomatoes in your meals at any point in the year. Sun Gold tomato plants grow aggressively because they are indeterminate and continue to produce fruit throughout the entire growing season.

If you hope to grow your own Sun Gold tomatoes, it is helpful to plant early in the growing season to produce the most fruit.

The Wide Array of Heirloom Tomatoes

Heirloom tomatoes are a non-hybrid cultivar and also open pollinated. Insects instead of chemicals naturally pollinate an open pollinated plant.

Because Heirloom tomato varieties are open pollinated, fruit production is genetically more diverse than other tomato types.

Heirloom Tomato Varieties

Growers utilize the seeds from the best producing Heirloom tomatoes to produce the largest yield from season to season. Compared to other common types of tomatoes, Heirlooms have a shorter shelf life and are less resistant to diseases like fusarium.

Delicious Brandywine Tomatoes

One kind of Beefsteak tomato is the Brandywine tomato plant. Brandywine tomato plants grow up to nine feet tall and have large potato leaves. The plant requires a lot of rain for proper fruit production – at least two inches of water per week.

The Brandywine tomato is a deep red color and is regarded as one of the best-tasting tomato varieties.

Because the tomato is so large, it is a great slicing tomato for BLT sandwiches. Additionally, Brandywine tomatoes are an excellent topping for a salad paired with other fresh vegetables.

Everything You Need to Know about Roma Tomatoes

Roma tomatoes go by a few different names. These tomato plants are also referred to as paste tomatoes or plum tomatoes. A Roma tomato is oval-shaped and significantly smaller than Beefsteak tomato types.

Plum tomato fruit has less juice and a chewy exterior flesh, making it great for sauces and canning. These medium-sized tomatoes are among the most common tomatoes at the grocery store because the harvest usually produces many tomatoes at a single time.

If you want to plant Roma tomatoes yourself, know that these tomatoes do not grow well indoors unless the conditions are similar to outdoor conditions regarding temperature.

How to Distinguish Grape Tomatoes

Grape tomatoes are incredibly healthy and an excellent topping for salads or enjoyed on their own. These tomatoes contain vitamins that promote eye, skin, and bone health and help the body fight infection.

Before purchasing grape tomatoes, you should know how to identify them in a grocery store correctly. Grape tomatoes are often confused with cherry tomatoes because they are tiny compared to other tomato types.

Cherry tomatoes are perfectly round, similar to cherries. On the other hand, Grape tomatoes are more oblong, similar to some grape varieties’ shape.

What are Big Beef Tomatoes?

Another Beefsteak tomato type is the Big Beef tomato plant. Big Beef tomatoes are hybrid plants that produce fruit up to six inches in diameter with an abundance of flavor.

Because Big Beef tomatoes are hybrids, the plant is easy to grow and has disease resistance. Commonly mistaken for Better Boy tomatoes, Big Beef produces fruit much quicker than other Beefsteak varieties.

Another benefit of Big Beef tomato plants is that the fruit grows even in undesirable conditions, like cool and wet weather. Big Beef tomatoes are popularly used for sauces and as a sandwich topping.

The Unique Story Behind Mortgage Lifter Tomatoes

The Mortgage Lifter tomato was created in the 1930s by a gardener who sold so many Mortgage Lifter tomatoes that it paid off his entire mortgage! This tomato variety is a popular taste test winner.

Mortgage Lifter tomato plants are indeterminate and grow fruit continuously on a plant that grows up to nine feet tall. The fruit is a large, low-acid, pink-colored fruit of the Beefsteak variety.

Growing the Cherokee Purple Tomato in the Fall

Growers across the country prefer Cherokee Purple tomatoes because they produce fruit in a variety of regions.

This type of tomato is most popular in the summer and early fall. The outside of a Cherokee Purple tomato is a dusky pink, while the inside is a deep red.

They only take about 6 weeks of indoor growing to be ready to plant and you get to choose from a wide range of varieties.

One of the problems gardeners often encounter with tomato plants are leaf blight diseases. Luckily, there are a number of early and late blight tolerant and resistant varieties on the market. So, try some of these this year in your garden.

'Iron Lady' is a determinate, red slicing variety with good resistant to blight and septoria leaf spot, as long as you grow it away from other blight susceptible varieties. 'Defiant' is a hybrid red, 6- to 8-ounce size variety with good leaf and root disease resistance.

'Mountain Magic' is a red cherry tomato that grows strong, produces lots of sweet, crack resistant fruit and doesn't get many leaf diseases. 'Matt's Wild Cherry' is a current-sized, red cherry tomato that is also a good disease tolerant choice.

For a nice saladette or plum-shaped, disease resistant tomato variety try 'Juliet', 'Plum Regal' and 'Valentine'. These varieties will produce an abundance of fruits for salads and canning.

As with any tomato, the healthier you keep the plant, the less problems you'll have. Plant, once the soil has warmed, in compost amended raised beds, keep the weeds away and water regularly. Trellis or stake tall plants to keep the fruits off the ground and mulch to slow the spread of diseases.
