Z. Tao, R. G. Henzell, D. R. Jordan, D. G. Butler, A. M. Kelly, C. L. McIntyre] Abstract : Stay green is an important drought resistance trait for sorghum production. QTLs for this trait with consistent effects across a set of environments would increase the efficiency of selection because of its relatively low heritability. One hundred and sixty recombinant inbreds, derived from a cross between QL39 and QL41, were used as a segregating population for genome mapping and stay green evaluation. Phenotypic data were collected in replicated field trials from five sites and in three growing seasons, and analysed by fitting appropriate models to account for spatial variability and to describe the genotype by environment interaction. Interval mapping and non-parametric mapping identified three regions, each in a separate linkage group, associated with stay green in more than one trial, and two regions in single trial. The regions on linkage groups B and I were both consistently identified from three trials. The multiple environment testing was very helpful for correctly identifying QTLs associated with the trait. The utilisation of molecular markers for stay green in sorghum breeding is also discussed.
