Research on the Progress of Systematic Taxonomy in the Genus <i>Asparagus</i> of China

Garden asparagus ( Asparagus officinalis &nbsp;L.) is a kind of nutritious and healthy vegetable with important economic value in the world. China has become largest production country garden But seeds mainly depend on import, so we need to innovate breeding system improve international competitiveness domestic varieties. Genetic analysis demonstrated that genetic variation was low its heterosis weak among cultivars. Inter-specific hybridization an means utilize heterosis, but relationship between classical taxonomy molecular phylogeny genus&nbsp; &nbsp;is disordered, which limits development interspecific breeding. In this genus, thirty-one species have been found China, effective resource for utilization among&nbsp; &nbsp;species. order provide reference next step clarify phylogenetic genus carry out hybrid near future, research progress reviewed study.
