"Stay-green QTLs effects on water extraction, transpiration efficiency and seed yield depend on recipient parent background"^^ . "A stay-green phenotype enhances the adaptation of sorghum to terminal\r\ndrought conditions, although the underlying physiological mechanisms leading to the\r\nexpression of stay-green remain unclear. Differences in tillering and leaf area at anthesis,\r\ntranspiration efficiency (TE), water extraction, harvest index (HI) and yield under both\r\nterminal drought and fully-irrigated conditions were assessed in 29 introgression lines\r\n(IL) developed targeting stay-green QTLs Stg1, Stg2, Stg3, Stg4, StgA, and StgB in S35\r\nbackground, and 16 IL developed targeting Stg1, Stg3, Stg4, and StgB in R16\r\nbackground. Transpiration efficiency was increased by StgB in the R16 background,\r\nwhereas there was no effect on this trait in the S35 background. Water extraction was\r\nincreased by Stg1 in the S35 background, whereas there was no effect in the R16\r\nbackground. StgB modified the proportion of water extracted before and after anthesis in\r\nthe S35 background. While tillering and leaf area at anthesis were decreased by Stg1 and\r\nStg3 in the S35 background, there was no such effect in R16. By contrast, yield data\r\nunder fully-irrigated conditions showed higher tiller grain yield in Stg1, Stg2, and Stg3\r\nILs. While yield differences were mostly explained by harvest index (HI) variation, the\r\nsubstantial yield variation unexplained by HI was closely related to TE in the S35\r\nbackground (R2 = 0.29), and more so in the R16 background (R2 = 0.72), while it was\r\nclosely related to total water extracted in the S35 background (R2 = 0.41), but not in the\r\nR16 background. These data indicate the potential for several stay-green QTLs to affect\r\ntraits related to plant water use and capture. However, they also show that these effects\r\ndepend on the interaction between genetic background and individual QTLs."^^ . "2011" . . . "38" . "7" . . "CSIRO Publishing"^^ . . .
