^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 ...
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.)
The Marglobe tomato is the parent of many tomato varieties, such as Rutgers. The Seed Savers Exchange yearbook lists several types of Marglobe variants, the: Marglobe F, Marglobe Improved, Marglobe Larson, Marglobe Supreme, and Marglobe Supreme F.
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 .
Differences in plant disease resistance are often incremental or quantitative rather than qualitative. The term quantitative resistance (QR) refers to plant disease resistance that is controlled by multiple genes and multiple molecular mechanisms that each have small or minor effects on the overall resistance trait.

A plum tomato, also known as a processing tomato or paste tomato, is a type of tomato bred for sauce and packing purposes. It is generally oval or cylindrical in shape, with significantly fewer locules (seed compartments, usually only two) than standard round tomatoes and a generally higher solid content, making them more suitable for processing into paste.
Darkening lesions on tomato leaves Advanced necrosis on tomato leaf. Stemphylium solani is of greatest concern in tomatoes, potatoes, peppers, garlic, onions, and cotton, though a wide range of over 20 species have proven susceptible. In tomatoes and potatoes, the resulting disease is known as grey leaf spot. In alliums it is known as leaf ...
