Tomatoes, Solanum lycopersicum (formerly Lycopersicon esculentum), are available in a wide range of fruit colors, sizes, shapes, and maturities. Ripe tomatoes may be red, orange, pink, yellow, white, or even green with shapes varying from globe or round to slightly flattened, pear-like, or cherry-sized.

Consumers sometimes complain that tomatoes purchased in grocery stores lack flavor or have tough skin. Although nurseries and garden centers can provide only a limited number of different tomato cultivars, home gardeners willing to grow their own tomato transplants can choose from among hundreds of tomato cultivars, selecting those with the color, texture, size, and taste they prefer. Although rumored, there is no direct link between fruit acidity and color. Yellow tomatoes, which many home gardeners believe have lower acidity, actually have a normal acidity level but also a higher sugar content, which changes the flavor (Figure 1).

When discussing tomatoes, the term cultivar, a contraction of the terms “cultivated variety,” refers to any group of plants with distinct characteristics that are preserved through controlled propagation, such as hybridization or cuttings. In contrast, the term variety refers to a subdivision of a species that evolved without human intervention, often within a distinct geographical area, and will breed true when isolated from other tomatoes. Often the term variety is used incorrectly to refer to any distinct tomato type. Almost all tomatoes should be referred to as cultivars, since even heirloom tomatoes were developed through years of human selection for plants with the best characteristics.

Certain tomato cultivars have been developed for special uses such as stuffing (Pink Stuffer, Yellow Stuffer, Striped Cavern) or longer storage (Burpee’s Long Keeper).

Very dwarf cultivars adapted for growth in pots or other containers also are available. Most of these “patio” cultivars have cherry-sized fruit, like Pixie II and Orange Pixie, although a few, like Bush Steak, Patio, and Patio Princess, produce regular-sized fruit.

Tomato Classification, Growth Habits and Pollination

Common tomato classifications include:

Tomatillos, and ground cherries are sometimes confused with tomatoes. These plants belong to the genus Physalis rather than the tomato genus Solanum.

Home gardeners should carefully consider the amount of space available in their garden when deciding which tomato cultivars to grow. Planting a combination of cultivars with different growth types will result in a long season of fresh tomatoes. The two most common growth forms for tomato plants are determinate and indeterminate.

Many tomato cultivars on the market today are hybrids. Tomato plants are self-pollinating, however, hybrid seed can be produced through a laborious process involving the hand crossing of two different parent plants. The resulting hybrid seed or progeny display specific characteristics inherited from the parent plants. However, when seed is harvested from the hybrid plants and grown out the following year, it will not grow true to type because of genetic recombination. Therefore, gardeners should not save seed from hybrid plants, with the expectation that the resulting plants will be similar to the hybrid parent.

Increasingly popular today are heirloom tomatoes. The definition of an heirloom tomato varies, but usually refers to open pollinated plants that were in cultivation before 1940, when the first hybrid cultivars became widely available. Often heirlooms have been passed down within families or communities for many years, with seed selected from the best plants each year. All heirlooms are open pollinated. Open pollinated plants, when isolated from other tomatoes, will grow true to type each year and their seed can be saved with the expectation of the same plant and fruit quality each year.

Most new tomato cultivars are resistant to or tolerant of certain diseases. This usually is indicated by a letter following the name, such as “N” for nematodes, “F” for Fusarium race 1, “FF” for Fusarium race 1 and 2, “FFF” for Fusarium race 1, 2 and 3, “T” for tobacco mosaic virus, and “V” for Verticillium wilt. Cucumber mosaic virus (CMV) and tomato spotted wilt virus (TSWV), Alternaria stem canker (ASC), gray leaf spot (St), and Septoria leaf spot (L) indicate additional disease resistance. Realize that not all tomato cultivars have the same level of resistance, and even resistant plants can become infected if disease pressure is very high. Some plants are labeled as tolerant to certain diseases indicating that they will produce fruit of acceptable quality even with moderate to high levels of disease infection.

Although open-pollinated heirloom cultivars are now popular, many have little genetic resistance to common diseases. These older cultivars should be planted in ground that has not had any Solanaceous crops (tomato, pepper, eggplant, or potato) for at least three years and in a place with good air circulation to reduce the opportunity for fungal infection.

All-American Selections (AAS) are cultivars tested at trial gardens across the United States. Cultivars must be unique, widely adapted, and provide a quality product to receive this honored award.

Early season tomatoes require 65 or fewer days from transplanting to harvest; main season tomatoes 70 to 79 days; and late season tomatoes more than 80 days.
