Abstract: The way of target character gene bank breeding is a new way of conventional breeding, which is introduced by the authors' my institute in order to improve initiative and purposefulness. It has combined germplasm innovation and breeding selection of new varieties. On the basis of classification of parental material, using the sterility line as tool, the authors' has constructed different target character gene banks, and has developed transgression breeding and innovation in germplasm utilizing the additive effect of gene in the gene bank and has used gene recombination and interaction of gene and gene mutation to develop combination breeding and improve variety and breed new varieties. They have combined all the innovated good characters in all the gene banks to develop new variety with good synthetic characters. The reserch institute of Millet Crops in Hebei Academy of Agricultural and Forestry Science innovated a set of pre maturity, super-prematurity materials using this method, and has developed many good new varieties with synthetic characters. These varieties showed prominent in national millet variety test and variety test. Four super-prematurity lines were developed, which could maturate normally at Ba-shang District in Hebei Provience. So the forbidden zone for millet breeding is broken through. Among the four lines, super-prematurity No.1 has sweet-straw, multi-spike and high crude protein. Super-prematurity No.2 has well-off iron, high crude protein and high crude fat. Key words: Millet; Target character gene bank; Breeding system
