Abstract: Black glume Sudan grass that isolated breeding and screening a few years was selected as female parent,'Tongza No.2’sorghum was selected as male parent hybridized with black Sudan grass in same year.After 4 generations of breeding,the hybrid showed lodging resistance,drought resistence,disease resistance,plant was thicker and taller than sudan grass,and the leaf blade was broader and longer,the adaptability was widened.The morphological character of hybrid was evidently differ from parents.The paper has summarized main morphology features,biological and economic characteristics of the hybrid.

Key words: Sudan grass, Sorghum, Hybridization, Yield
