Comparative analysis of two Alfalfas (Medicago sativa L.and M.f alcata L.) using SSR,EST-SSR and morphological traits

摘要：

Medicago sativ a L.is one of the most important forage in China.M.f alcata is an important species for alfalfa breeding because it has high resistance to cold and drought.Chinese alfalfa breeders have bred some varieties using Medicago sativ a L.crossing with M.falcata.But there is no any knowledge of genetic distance on the two species till now, which limits further breeding.The molecular marker technique has been used for analysis of the genetic diversity of alfalfa (Li,1998).In this paper,we compared the genetic distance of different alfalfa varieties using the morphological character and molecular marker technique such as SSR and EST-SSR, which can provide guidance for alfalfa breeding.
