Stay-Green Trait Associated with Yield in Recombinant Inbred Sorghum Lines Varying in Rate of Leaf SenescenceA KBorrellauthorF RBidingerauthorKSunithaauthor160 recombinant inbred lines, developed from a cross between a senescent and a stay-green sorghum line, were grown in S. India. Relationships between stay-green, grain yield and yield components were investigated. Grain yield under post-anthesis stress conditions was correlated with grain number and, to a lesser extent, grain size. Grain number was correlated with green leaf area at anthesis. The stay-green trait was associated with higher leaf N status and transpiration efficiency.Sorghum1999International Crops Research Institute for the Semi-Arid TropicsArticle
