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

摘要

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 variation between plants to attain these objectives. Successful adaptation to environmental conditions and success in plant breeding are governed by the extent of the genetic base, as measured by genetic diversity. Genetic variation is needed to address many problems in plant breeding and it is obtained from the genetic diversity contained within the plant genetic resources (such as landraces, primitive forms, wild relatives and weedy races, etc.).Digital Object Identifier http://dx.doi.org/10.1080/09064710903573390
