Developments in the meiotic analysis of hybrids. I. Review of theory and optimization in triploids.

abstract：:Pinewood nematode (Bursaphelenchus xylophilus) is an invasive species that causes a destructive forest disease-pine wilt disease. This disease has been prevalent in some countries in Asia since the 1970s. An amplified fragment length polymorphism survey was used to compare the genetic variation of native and invasive ...
