Abstract: From 1988 to 1992 , selective breeding of superior plants of Myrica rubra was done in seven main producing homes of Zhejiang , such as Cixi , Yuyao , Huangyan etc .31 superior plants were breeded by grafting , which were selected among eight varieties , and their collective region was set up .Then the relative concentrative resource pool of main varieties of Myrica rubra was constructed in forestry center of Quxian County .It had been not only transformed into producing material , was also provided advantageous to hybridize and to improve variety .Biji bayberry showed the finest bearing properties among all clones , which bearing time and output were in the first place , but Dongkui bayberry fruited later , its output was low , and other varieties were in the middle of them in this aspect .The first fruiting weights of Biji and Dongkui bayberry were lower than their mother trees , but the difference of Dongkui bayberry was insignificant , and its fruit was still big and the properties could be bequeathed , and nutritional shortness could be reason of small fruits temporarily .The environmental factors , such as light , hotness and humidity etc ., could result in advancing of maturation period of all clones by 5 ～ 8 d.
