Abstract excerpt
BACKGROUND: Spike morphology is an important characteristic of common wheat because of its effects on yield potential. However, few available genes regulating spike morphology have been reported in common wheat. RESULTS: We identified a compact spike mutant S-Cp2, which was obtained by treating common wheat cultivar ‘Shumai482’ with ethyl methanesulfonate. The gene responsible for the compact spike phenotype of...
