Abstract: The characteristic with the plant material produce of the breed of the different Forage Sorghum,and its ecosystem adaptability in the huhtrot was researched. Tlre result demonstrated: tire growth progress about the different brc}:}l had the existence of significant difference. Among then:Jumbo,Everlush,Muteli,Pacemaker can't take out the flower' from the spike normally, therefore can't be mature. Tlre plant height, the Mengnong Qingsi No.l most quickly, the Muteli most slowly, the uuml>crof the clear leaf and the spread leaf of the different bread of Forage Sorghum changed following the curve of "S". After August 19th,the stub highness of the different breed reached the maximum respectively in succession, the Superdan highest,277cm, the Muteli shorter, TheSUmber of the clear and spread leaf of the Muteli increa,dmost quickly.the leaf in the caulis was at most, l R.8 slices; the Jumbo slowest, the leaf in the caulis at least,13.8 slices. The ratio of the stalk and leaf of Forage Sorghum changed following the double peak curve, and the ratio of fresh and chy leaf single peak, the peak value on June 24th around. At all generational progress, the yield of fresh grass changed following sine peak curve and the peak value of each breed appearing on Sept.l2th around, the Muteli for 7280tks/hMengnongrrr at mostqings No.lfor 42.464km at least. Among each breed, the yield of hay of theat most, the Everlush, at least.
