Sorghum stover consisting of stalks and leaves collected from production fields after grain harvest is a significant source of feed for livestock across West Africa. Improving the dry matter yield and the nutritional value of stover from locally-adapted sorghum varieties may contribute to mitigation of animal feed shortages that are common in this region. The Brown midrib (Bmr) Bmr6 and Bmr12 genes were introgressed in two Nigerien elite sorghum varieties for stover improvement. The parental lines and derived progenies were tested in replicated field trials for differences in agronomic performance including grain and stover production. The stover samples were characterized for differences in nutritional characteristics including dry matter, NDF (Neutral Detergent Fiber), ADF (Acid Detergent Fiber), ADL (Acid Detergent Lignin). Statistical analyses indicated highly significant differen.. View More»
