Characteristics：mediate maturing,in northeast area and Norht China,from emergence to the main ear maturity needs 95 days, effective accumulated temperature above 2600℃,plant height 200cm,branching 3-5 branches,earbearing 6-10,ear length 50-100cm,100-kernel weight 41-45g,seed oil content 53%,developed root system,vigorous growth,droughts as well as saline and alkaline resistant,and after ripe no ballisstic fruit,no shattering.

Yield performance：average yield 300kg per mu,high yielding cultivation 350kg,single plant production potential 1500g.

Appropriate region：suitable in area across China with frost-free period more than 130 days and effective accumulated temperature above 2600℃.

Key cultivation techniques：plot with above medium fertility.Per mu suitable density about 700 plants,two seeds for each hole,4 leaves for the singling,one plant per hole,re-apply bud fertilizer.40 days before frost,make topping to promote grain filling and increase grain weight.
