More premature, in the suburbs of Beijing Summer Broadcasting crop growth period of about 85 days. Plant height of 1.5-1.8 meters, 10,10 shorter than the original hybrid 40-50 cm, is conducive to reducing the contradiction between the next crop. No tiller, tight spike, spike length of about 25 cm. Red shell, orange particles, grain weight 25.1 grams, 36 grams per grain weight about. The shell rate is low, the quality of the lower middle. Plant growth and tidy, disease resistance, insect resistance, lodging. In 1975 to participate in the summer suburbs of Beijing suburbs sorghum varieties joint test, the top three in the production of seven points, the average yield of 225 pounds, up to 380 pounds.
