南7单交系四川万县地区农科所用自选自交系南21—3作母本,75—1作父本,杂交选育的中晚熟玉米单交种,1986年4月经四川省审定定名。1987—1989年在我区经区域试验和较大面积示范种植,主要优点是:生长整齐,产量高,抗逆性强,品质较好,熟期适中,是中高山区较理想的接班品种,可在海拔1200m
Southern 7 single family diplomacy Department of agriculture in Sichuan Wanxian use optional inbred line Nan 21-3 as the female parent, 75-1 as the male parent, hybrid selection and breeding of medium-late maturing corn single cross in 1986 April by the Sichuan Province . 1987-1989 years in our region by the regional experiment and large-area demonstration planting, the main advantages are: neat growth, high yield, strong resistance, good quality, moderate maturity, is the ideal follow-up varieties in the mountainous areas, Available at 1200m above sea level
