Agronomic performance and feeding value of brown midrib sorghum

orghum bicolor is an annual forage source with good fitness and resistance. Although the mutants of brown midrib sorghum are able to increase high feeding value by reducing lignin content, they reduce the agronomic performance. This study reviewed the progress of bmr sorghum at abroad from forage quality, agronomic performance and feeding value, and propose the future focuses, which would provide useful information for bmr sorghum research.
