More Information
Summary:The invention discloses a method for selective breeding middle-late-maturing high-yield hybrid corn, the excellent middle-late-maturing hybrid corn with high yield, high quality, strong stress resistance and good adaptability is bred by crossing T0278 as the female parent and T0270 as the male parent. The excellent hybrid corn selective bred by using the invention with a yield increase of more than 5% relative to the main hybrid corn at present, has the advantages of uniform filaments, strong viability, high maturing rate and good anther dehiscence of tassel. The spring sowing growth duration in Liaoning Province of the hybrid corn is about 133 days, which is one day later than Zhengdan 958, so that the needed effective accumulated temperature is about 2865 DEG C. The hybrid corn has tough and tensile stalk, developed root system, lodging resistance, strong drought resistance, mature stalk, and high and stable yield, which is a middle-late-maturing corn suitable for growing in Shenyang, Tieling, Jinzhou, Chao
