The "triangle of U" diagram, showing the genetic relationships among six species of the genus Brassica. Chromosomes from each of the genomes A, B and C are represented by different colours. The triangle of U (/ uː / OO) is a theory about the evolution and relationships among the six most commonly known members of the plant genus Brassica.
Wisconsin Fast Plants were initially developed as part of a larger breeding project of Rapid-Cycling Brassicas, originating in the early 1970s. [1] Wisconsin Fast Plants and other Rapid-Cycling Brassicas were selected through conventional plant breeding to be a tool that would speed up genetic research for disease resistance in economically important Brassica crops.

The host range of X. campestris pv. raphani is wider than X. campestris pv. campestris and includes Brassica spp., radish, ornamental crucifers like wallflowers and tomato. Symptoms include circular dark spots that later became light brown or gray, sometimes surrounded by a water-soaked halo.
Brassica rapa is a plant species that has been widely cultivated into many forms, including the turnip (a root vegetable), komatsuna, napa cabbage, bomdong, bok choy, and rapini. Brassica rapa subsp. oleifera is an oilseed commonly known as turnip rape , field mustard , bird's rape , and keblock .
There are around 350 genera in the plant family Brassicaceae.The type genus is Brassica (cabbage and mustards). Genera with a large number of species are Alyssum (madworts), Arabis (rockcresses), Cardamine (bittercresses), Draba (whitlow-grasses), Erysimum (wallflowers), Heliophila, Lepidium (pepperworts), Noccaea, Odontarrhena, Physaria (bladderpods), and Rorippa (yellowcresses).
Brassicaceae (/ ˌ b r æ s ɪ ˈ k eɪ s iː ˌ iː,-s i ˌ aɪ /) or (the older) Cruciferae (/ k r uː ˈ s ɪ f ər i /) [2] is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family.
The mustard plant is any one of several plant species in the genera Brassica, Rhamphospermum and Sinapis in the family Brassicaceae (the mustard family). Mustard seed is used as a spice. Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as prepared mustard.
In Scottish and some other English dialects, the word turnip can also refer to rutabagas (North American English), also known as swedes in England, a variety of Brassica napus, which is a hybrid between the turnip, Brassica rapa, and the cabbage. Turnips are generally smaller with white flesh, while rutabagas are larger with yellow flesh.
