Review of the Research Associated with Heterosis and Polyploidization in Plants

  • Received Date: 2013-08-21
  • During the process of evolution and formation of new plant species, the hybridization of two parent lines can produce F1 offspring with more excellent traits e.g. fast growing, high yielding and strong environmental adaptability. This is named heterosis or hybrid vigor. In addition, based on the polyploidization of homologous or heterogenous genomes, the polyploid plants can aslo show some traits which are superior to their parent lines. Consequently, hybridization and polyploidization have been regarded as the most important driving forces to promote plant evolution and formation of species. Moreover, heterosis and polyploidization have been widely used in agriculture, and bring enormous economic and social value. It suggests that it is very important and valuable to explore the nature basis of heterosis and polyploidization in plants which have attracted much attention. During the past years, rapid progress was made in the research associated with heterosis and polyploidization. This review aims at summarizing the research progress, and discussing the present and future research on heterosis and polyploidization of woody plants.

Review of the Research Associated with Heterosis and Polyploidization in Plants

  • 1. College of Life Sciences, Nankai University, Tianjin 300071, China

Abstract: During the process of evolution and formation of new plant species, the hybridization of two parent lines can produce F1 offspring with more excellent traits e.g. fast growing, high yielding and strong environmental adaptability. This is named heterosis or hybrid vigor. In addition, based on the polyploidization of homologous or heterogenous genomes, the polyploid plants can aslo show some traits which are superior to their parent lines. Consequently, hybridization and polyploidization have been regarded as the most important driving forces to promote plant evolution and formation of species. Moreover, heterosis and polyploidization have been widely used in agriculture, and bring enormous economic and social value. It suggests that it is very important and valuable to explore the nature basis of heterosis and polyploidization in plants which have attracted much attention. During the past years, rapid progress was made in the research associated with heterosis and polyploidization. This review aims at summarizing the research progress, and discussing the present and future research on heterosis and polyploidization of woody plants.
