The use of plant genetic resources and biodiversity in classical plant breeding

Abstract

Variation in plant populations is very important for plant breeders. The basic aims of plant breeding are 'high yield, high quality and quantity, extension of adaptation ability to climate and soil conditions and tolerance or resistance to pests and diseases'. Plant breeders use the genetic variations between plants to attain these objectives. Successful adaptation to environmental conditions and success in plant breeding are bounded by the range of the genetic base, as measured by genetic diversity. Genetic variation is needed to address many problems in plant breeding and it obtained from the biodiversity within the plant genetic resources (such as Breeding lines, Landraces, Primitive Forms, Wilds and Wild relatives, Weed races, etc.). © 2011 Taylor & Francis.
