TLDR
An attempt is made to provide a framework in which both taxonomy and infraspecific classification can operate with a minimum of confusion.Abstract:
The methods of formal taxonomy have not been very satisfactory for the classification of cultivated plants. As a result, the people who deal with cultivated plants the most have developed their own informal and intuitive classifications based on experience as to what constitutes useful groupings. An attempt is made to provide a framework in which both systems can operate with a minimum of confusion. The structure of the total available gene pool is characterized by assigning taxa to primary, secondary and tertiary gene pools. At the infraspecific level, cultivars are grouped into races and subraces in an informal way without rigid rules for the use of terms.read more

Origin, dispersal, cultivation and variation of rice.
TL;DR: There are two cultivated and twenty-one wild species of genus Oryza, the Asian cultivated rice is grown all over the world and the African cultivated rice, O. glaberrima, probably domesticated in Niger river delta.
Journal ArticleDOI
Comparative evolution of cereals.
TL;DR: The gene pool classification suggested by Harlan and de Wet (1971) is used in order to treat the several cereals on a uniform basis and is not intended to be a formal taxonomic system but rather a simple device to bring a genetic focus to bear on the taxonomies already available.

TL;DR: An updated inventory of the vascular flora alien to Italy, providing details on the occurrence at regional level, is presented in this paper, which includes 1597 species, subspecies, and hybrids, distributed in 725 genera and 152 families; 2 taxa are lycophytes, 11 ferns and fern allies, 33 gymnosperms and 1551 angiosperms.
Journal ArticleDOI
The origin, evolution, cultivation, dissemination, and diversification of Asian and African rices
TL;DR: Both the African and Asian rices are still undergoing evolutionary changes at habitats where the wild, weed, and cultivated races co-exist, largely due to cultivators' preferences, socio-religious traditions, and population pressure.
