The standard is: brown midrib; plant height 140~ 160cm; the total number of leaves is not less than 30 pieces; the tillering ability is strong, and the effective number of tillers per plant is 2 to 4; the difference between the height of the tiller stem and the main stem does not exceed 5cm, and the difference between the flowering period does not exceed 7 days; 25-30cm; medium-tight spike shape; seed-setting rate over 98%. Then carry out backcross breeding with the common sorghum CMS line, select completely sterile BMR individual plants with the same agronomic characteristics as the forage-type BMR sorghum maintainer line in the backcross population, and finally obtain the forage-type BMR sorghum CMS line. The forage type BMR sorghum sterile line selected by the invention enriches the gene bank of the sorghum sterile line.
