Abstract

Jiangdan No.2 was bred by the Maize Research Institute of Heilongjiang Academy of Agricultural Sciences.The inbred line JS1 was used as the female parent and JS2 as the male parent.The hybrid showed some good features,such as high yield,stable yield,high-resistance to disease and strong adaptability.It needs effective temperature of 2 006℃ over 10℃.Its biomass yield was from 77 710.3 to 81 962.1 kg·hm-2 in general level of production,it could be planted in the first accumulated temperature zone of Heilongjiang province.
