Genetic Diversity of Rice Landraces in Yuanyang Hani Terraced Rice Fields Under In-situ Conservation: Research Progress

Taking the current situation of rice landrace in Yuanyang terrace rice fields as an example, the genetic diversity of phenotype and molecule of rice landraces, the effects of ecological environment under in-situ conservation, mainly including geographical conditions and biological factors and the influence of local traditional knowledge and culture on the diversity of rice landrace in Yuanyang County were reviewed. The superiority of protecting rice varieties under in-situ conservation was explored to provide a scientific basis for the protection of rice landraces and related agricultural crop resources.
