ISSR and ITS analysis on genetic diversity of 15 white clover cultivars

The relationship of genetic diversity with geographical origin between 15 white clover cultivars on the popularization and application of the large area in China, which provides genetic theory support the white clover breeding. The results showed that 15 white clover cultivars were divided into two categories, the class Ⅰ has 10 cultivars of white clover, mainly comes from Denmark, Australia, New Zealand and the Netherlands; There are five white clover cultivars in the class Ⅱ, mainly comes from USA, China and Argentina. White clover cultivars clustering has certain regional distribution, the genetic diversity of white clover cultivars could be studied by using ISSR and ITS analyzing , and ISSR can be more detailed on the classification.
