Plant genetic resources and breeding: current scenario and future prospects.

Abstract

Variation in any plant population is very important for breeders. Basic aim(s) of the plant breeding is/are high yield, quality and quantity, development, resistance or tolerance of adaptation ability to stress factors, etc. They are being utilized from the genetic variation to be able to manage all these component(s). On the other hand, an accomplished adaptation to environmental conditions and ‘success’ of the plant breeding is limited with genetic base (or gene pools) of the organism. Therefore, this wideness is measured by density of the biological diversity or biodiversity/bioversity. Aboveall, variation (genetic, among species, ecosystems, etc.) is essential for all kind of the plant breeding activities and obtained from the PGRs fundamentally (such as breeding lines, landraces, local varieties, primitive forms, wild & wide relatives, weed races, etc.). © 2011 Friends Science Publishers
