The Origin, Distribution and Classification of Cultivated Broccoli Vari

The Origin, Distribution and Classification of Cultivated Broccoli VarietiesOf the many contrastive vegetable crops now under cultivation in both the U.S. and abroad, atomic number 53 that has gained increasing importance is that of broccoli. Although it does not constitute a significant fragment of most peoples diets, it has notwithstanding experienced a kind of revival in recent years and has become increasingly popular (Schery, 1972 Heywood, 1978). It may blush be said that broccoli has emerged from relative obscurity and attained the place of a worthwhile garden vegetable,(Talbert, 1953). The botanical family to which broccoli belongs is the genus Brassicaceae, also cognise as the Mustard family. The Brassicaceae is a large family comprised of approximately 3,000 describe species apportioned among 350-380 genera. The precise number of genera will vary depending on the authority(Heywood, 1978 Keil & Walters, 1988). The salmagundi scheme for broccoli and indeed all of the o ther brassicas is clear and truthful until one reaches the species level. At that point the addition of numerous subspecies, varieties, and cultivars results in a rather complex and confusing arrangement of-the taxa in question. For example, the scientific report for broccoli, Brassica oleracea (L.), is also shargond by cabbage, Chinese cabbage, cauliflower, collards, brussels sprouts, kale, kohlrabi, and tronchuda kale, to plant a few. Despite the fact that all of the aforementioned varieties are sympathetic to one another and to broccoli, and are therefore referred to as B. oleracea, they are nevertheless separate entities. Most authorities today consider there are two major varieties of broccoli, B. oleracea (L.) var. botrytis or cauliflower broccoli and B. oleracea ... ...Heywood, V.H. 1978.
