The genus Brassica includes several economically important plants. They are used as vegetables, fodder, and as a source of vegetable oil and condiments. Several species are rich in vitamins and anti-carcinogenic compounds. There are six Brassica species growing throughout the world. Three of those are diploid - B. rapa (AA genome type, 2n=20), B. nigra (BB genome type, 2n=16), and B. oleracea (CC genome type, 2n=18) which have hybridized to give rise to three amphidiploids, B. napus (AACC, 2n=38), B. juncea (AABB, 2n=36), and B. carinata (BBCC, 2n=34). These different species exhibit different morphological characteristics. Many groups throughout the world have been working on various aspects of Brassica genome. In 2002 it was decided to integrate various Brassica projects under the Multinational Brassica Genome Project. Information about it is being maintained at the Brassica Genome Gateway website. B. juncea(Indian mustard) is a major oilseed crop. It is a polyploidy species with AABB genome type and 18 haploid chromosomes. It contains high levels of polyunsaturated fatty acids which makes it healthy for human consumption and several varieties are drought and heat tolerant.
