Although coreless, it is somewhat seedier and sweeter than normal paste cultivars. They ripen ca. 80 to 85 days after planting. [3] The plant is an indeterminate variety, growing continually until it dies. (Like all tomato plants, it is a tender perennial, which would not die if growing in the warm climate to which tomatoes are native.)
^Explanation of tomato disease resistance codes [145] Some tomato cultivars will be marked with disease resistance codes, signifying that the plant is immune to a certain disease shown below: A — Alternaria stem canker; F — Fusarium wilt; FF — Fusarium races 1 and 2; FFF — Fusarium races 1, 2 and 3; N — Nematodes; T — Tobacco mosaic ...
VFN in horticulture stands for Verticillium wilt, Fusarium, and Nematode disease resistance in tomatoes. [1] Most hybrid tomato varieties are labeled with some combination of one or more of these three letters, since disease resistance is a large part of the reason to hybridize tomatoes .
In the UK, Zeneca produced a tomato paste that used technology similar to the Flavr Savr. [19] Don Grierson was involved in the research to make the genetically modified tomato. [ 20 ] Due to the characteristics of the tomato, it was cheaper to produce than conventional tomato paste, resulting in the product being 20% cheaper.
Plant diseases can also be partially controlled by use of pesticides and by cultivation practices such as crop rotation, tillage, planting density, disease-free seeds and cleaning of equipment, but plant varieties with inherent (genetically determined) disease resistance are generally preferred.

Organic heirloom tomatoes. An heirloom tomato (also called heritage tomato in the UK) is an open-pollinated, non-hybrid heirloom cultivar of tomato. They are classified as family heirlooms, commercial heirlooms, mystery heirlooms, or created heirlooms. They usually have a shorter shelf life and are less disease resistant than hybrids.

The Sw-5 resistance gene in tomato is a dominant resistant gene. [17] The Sw-5 gene gives resistance to the TSWV through a hypersensitive response. [18] A hypersensitive response is when the plant cells that surround the infection undergo cell death, which would then deprive the virus of the cell machinery it needs to replicate and infect the ...
