Introduction Stem brittleness significantly affects both yield and quality of maize. Methods Using phenotypic identification sequence analysis, we identified a new brittle stalk maize mutant. Furthermore, assessed its feeding value by content determination cellulose, hemicellulose, lignin crude fiber, starch, protein contents. Results Here, mutant, bk-5 214S2L , an allelic variant . The stem was similar to that but not identical. Unlike leaves did fall off completely stems break in windy conditions. We missense mutation (C>T) the fifth exon candidate gene Zm00001d043477 resulting amino acid change from serine leucine at position 214. A significant reduction cell wall thickness leaf veins compared with inbred line RP125. Among major components leaves, total were lower than also evaluated application silage found detergent fiber contents reduced RP125, while remained unchanged. tannin improved palatability for livestock. Conclusion Overall, is high-quality genetic resource breeding forage grain-feed
