Sugarcane smut (Sporisorium scitamineum (Syd.) M. Piepenbr., M. Stoll & Oberw.; formerly named, Ustilago scitaminea Syd.) causes reduction in cane yield and cane juice quality. Seedling progeny of twelve sugarcane families were screened for their smut reaction to assess parental contribution of smut resistance on progeny performance and to identify any associations between smut rating and yield and yield components. The progeny of twelve families were inoculated by dipping two month seedlings in a spore suspension at the concentration of 5 x 106 spores ml-1. Smut incidence was recorded on both plant and ratoon crops. According to the smut incidence…
