Diachronic analysis showed no significant changes in the level of genetic diversity occurred over the past 27 years’ domestication, which indicated genetic diversity was successfully maintained under on-farm conservation. Rice (Oryza sativa L.) is one of the earliest domesticated crop species. Its genetic diversity has been declining as a result of natural(More)
Due to the rapid diffusion of improved crop varieties, fewer and fewer landraces are being grown by farmers. The on-farm conservation of crop landraces has been proposed as means of conserving potentially important crop germplasm as an alternative to its ex situ conservation in gene banks, but the effectiveness of this approach is unproven.
