Establishment of Mapping Population in Eucommia ulmoides

Based on the variation analysis of the growth and leaf traits and the contents of total flavonoids among seven F1 families of Eucommia ulmoides,and combining the detection of the levels of polymorphisms between parents using AFLP,cross combination of Xiaoye × Qinzhong No.1 was selected as the mapping population,whose variation was higher than others.It is the basic step in mapmaking and identifying the molecular markers linked to some important traits.
