This invention relates to the field of plant breeding. In particular, this invention relates to new tomato, Solanum lycopersicum, varieties denominated ‘H1292’ and ‘H1293.
Breeding for improved tomato varieties involves providing genetics that give an advantage to the grower, processor, consumer, or other member of the supply chain. The improvement may be in the form of field performance, disease resistance, factory performance, or a fruit quality characteristic. For a tomato variety to be suitable to be grown for processing, the variety must have a concentrated fruit setting and maturity, firm fruit, and sufficient rot tolerance to allow early fruit to remain rot-free while later fruit continues to develop and ripen.
Most commercial processing tomato varieties are hybrids resulting from a cross pollination of two true-breeding, inbred parents. Through the use of true-breeding lines, a hybrid is produced that often displays characteristics of each parent, and often demonstrates characteristics that are superior to either parent alone, or that allow a hybrid to mask inadequacies of the individual parents.
Processing tomato varieties typically have a blocky to blocky-oval shape. However, an elongated shape that is referred to as a “pear” shape is preferred for some products and some market areas. Thus, a pear tomato variety (i.e., having a pear shape) can be valuable for certain products and markets.
In order to meet this need, the present invention provides a new and improved process tomato varieties ‘H1292’ and ‘H1293’, which are pear tomato varieties with improved yield, brix, and disease resistances, as compared to the industry standard tomato variety ‘H2601’. The varieties ‘H1292’ and ‘H1293’ are pear-shaped varieties with resistance to Verticillium race 1, Fusarium races 1 and 2, root knot nematode, and the tomato spotted wilt virus. The fruit of ‘H1292’ is firm with an average weight of 71.8 grams, and peels easily. The fruit of ‘H1293’ is also firm with an average weight of 72.1 grams, and peels easily. Additionally, ‘H1292’ and ‘H1293’ each has a level of fruit rot tolerance that makes the variety very adaptable for once-over machine harvest in regions such as California, Italy, and other countries with a Mediterranean climate.
The characteristics that determine the quality of tomato fruit used for processing are different from that of tomato fruit used for the fresh market. Processing characteristics are commonly tested on samples of tomato juice produced in a way that is well known in the art. For example, tomatoes are cooked in a microwave oven for several minutes, lost water is replaced, and the sample is poured into a pulper-finisher to remove skin and seeds and produce a uniform juice sample. Once cooled to room temperature, various tests can be run on the juice including juice Bostwick (a measure of gross viscosity or consistency), refractometer solids to measure soluble sugars and acids, pH, and color via Hunter a/b score. The Hunter a/b score is an international industry and USDA standard color measurement of tomato products that provides a representation of the color of the product in a single dimensionless unit. The “a” value represents color on the green to red dimension whereas “b” represents the blue to yellow dimension; a higher a/b ratio is associated with more red color and is often considered a superior product.

Described herein are new and distinct tomato varieties named ‘H1292’ and ‘H1293’ that were developed to provide ground-culture hybrid tomato varieties (i.e., not grown on stakes) that are suitable for machine harvest, and is adaptable to the climactic conditions of regions such as California, USA, and Italy.
Plants of tomato varieties ‘H1292’ and ‘H1293’ are resistant to Verticillium wilt race 1, Fusarium wilt races 1 and 2, root knot nematode, and tomato spotted wilt virus. Additionally, plants of the tomato varieties ‘H1292’ and ‘H1293’ are dark green in color and medium in size compared to other tomato varieties of the same market class. Fruit from the tomato variety ‘H1292’ is firm and peels easily. Moreover, the tomato varieties ‘H1292’ and ‘H1293’ are adapted to culture in regions such as California, USA, and Italy.
The tomato varieties ‘H1292’ and ‘H1293’ are uniform and stable within commercially acceptable limits. As is true with other tomato varieties, a small percentage of variants can occur within commercially acceptable limits for almost any characteristic during the course of repeated multiplication. However no variants were observed during the two years in which the variety was observed to be uniform and stable.
Additional methods include, without limitation, chasing selfs. Chasing selfs involves identifying inbred plants among tomato plants that have been grown from hybrid tomato seed. Once the seed is planted, the inbred plants may be identified and selected due to their decreased vigor relative to the hybrid plants that grow from the hybrid seed. By locating the inbred plants, isolating them from the rest of the plants, and self-pollinating them (i.e., “chasing selfs”), a breeder can obtain an inbred line that is identical to an inbred parent used to produce the hybrid.
Accordingly, another aspect of the present invention relates a method for producing an inbred tomato variety by: planting seed of the tomato variety ‘H1292’ or ‘H1293’; growing plants from the seed; identifying one or more inbred tomato plants; controlling pollination in a manner which preserves homozygosity of the one or more inbred plants; and harvesting resultant seed from the one or more inbred plants. The step of identifying the one or more inbred tomato plants may further include identifying plants with decreased vigor, i.e., plants that appear less robust than plants of the tomato variety ‘H1292’ or ‘H1293’. Tomato plants capable of expressing substantially all of the physiological and morphological characteristics of the parental inbred lines of tomato varieties ‘H1292’ and ‘H1293’ include tomato plants obtained by chasing selfs from seed of tomato varieties ‘H1292’ and ‘H1293’.
One of ordinary skill in the art will recognize that once a breeder has obtained inbred tomato plants by chasing selfs from seed of tomato variety ‘H1292’ or ‘H1293’, the breeder can then produce new inbred plants such as by sib-pollinating, or by crossing one of the identified inbred tomato plant with a plant of the tomato variety ‘H1292’ or ‘H1293’.
