Advance on Peanut Breeding of High-yielding and Good-quality and the Application of Biological Technology

In this paper the challenge to peanut industry of China caused by the change of market demand after China entering WTO was analyzed, the demand and orientation of China peanut breeding was summarized based on the yield, quality and resistance. In the same tine, the advance on the breeding of new peanut cultivars, the peanut principle of high-yielding, good-quality and strong resistance and genetic study in recent years were introduced briefly in this paper, and the application of molecular marker technology on peanut genetic diversity and identification of variety, molecular assistance marker were mainly summarized, and the valuable experience and the foreground of DNA molecular marker technology using on peanut breeding was discussed intensively.
