Development of Crop Heterosis in Molecular Genetics

  

  • Online:2003-06-25 Published:2003-06-25

Abstract: Heterosis is a natural phenomenon widely existing in crops, the genetic mechanism of which was exploited in the past. With the development of molecular biology, the mechanism was further elucidated at the molecular level. In this paper, we reviewed the relationship between difference of molecular marker in the genome and heterosis, the effect of quantitative trait loci (QTL) on heterosis and the influence of genetic expression and regulation to heterosis. Utilization of chip technique in heterosis study was also prospected.
