Abstract: A new millet (Setaria italica Beauv) varity, super-early maturity No.1, with sweet-stalk and multi-spike was developed through several years of study by using target character gene bank in breeding. This variety has five outstanding characters. Firstly, super-early-maturity, the variety only need 1550℃ effective accumulated temperature and can normally mature in the Bashang Region in Hebei Province, thus could break through the forbidden zone of millet cultivation and move the margin of millet growth northward greatly. Secondly, this variety is a rare idioplasm of multi-spike, its branch can grow into spike and the burl in its middle and lower part can outgrow several spikes. Thirdly, its straw is sweet and has a high content of sugar. The whole-sugar, dissolvable sugar and deoxidized sugar in its straw are 74.8%, 200.5% and 237.2% higher than the common varieties, respectively, in the same region. Fourthly, high-content crude protein, which is higher than the common varieties by 3.9% to 30.4%. Fifthly, the color of grain is changeable. The grain of super-early-maturity No.1 is red in Shijiazhuang, but yellow in Bashang region. Also, this variety possesses the character of high quality and yield. In this article, the innovation way is introduced.
