利用A3细胞质抗败育和中国高粱根茎长及亨加利高粱株高杂种优势强的特点,育成了抗败育、长根茎、抗旱耐深播A3SX-1A。用该系与苏丹草杂交育成饲草高粱晋草1号,山西省区试结果表明:晋草1号在两年13个点次中全部增产,二次刈割平均产鲜草150 792Kg/hm2,比对照增产10.8%,该草长势强,根系发达,分蘖性好,抗紫斑病、抗旱、抗倒伏、刈割后植株再生力强、生长速度快,是农田刈割草地的优良品种。晋草1号植株含粗蛋白15.29%(以干基计),粗脂肪2.96%,无氮抽出物32.29%。成熟期茎秆含糖200(BX)左右,是青刈、青贮饲养牛、羊、鱼的优质饲料。
A3SX-1A was bred to resist abortion, grow rhizomes and drought tolerant by using characteristics of A3 cytoplasm abortion resistance and strong heterosis of Chinese sorghum rhizome length and Henggali sorghum plant height. The forage sorghum Jincao No. 1 was crossed with Sudan grass by this line. The results of the district test in Shanxi showed that Jincao 1 all increased yield at 13 points in two years, and the average yield of fresh grasses 150 792kg / hm2 , Yielding 10.8% more than that of the control. The grass grows strong, developed roots, good tillering, purple stain resistance, drought resistance, lodging resistance, strong plant regeneration after mowing, fast growth, is an excellent variety mowing grassland. Jincao No. 1 plant contains 15.29% crude protein (dry basis), 2.96% crude fat and 32.29% nitrogen-free extract. Mature stalk sugar about 200 (BX), is green mowing, silage cattle, sheep, fish, high-quality feed.
