Research (ACIAR) (CIM-2007-120). Authors are grateful for the expert technical help
from Mr N Pentaiah and Mr M Anjaiah. The lysimetric facility was developed by a grant

drought conditions, although the underlying physiological mechanisms leading to the
expression of stay-green remain unclear. Differences in tillering and leaf area at anthesis,
transpiration efficiency (TE), water extraction, harvest index (HI) and yield under both
terminal drought and fully-irrigated conditions were assessed in 29 introgression lines
(IL) developed targeting stay-green QTLs Stg1, Stg2, Stg3, Stg4, StgA, and StgB in S35
background, and 16 IL developed targeting Stg1, Stg3, Stg4, and StgB in R16
background. Transpiration efficiency was increased by StgB in the R16 background,
whereas there was no effect on this trait in the S35 background. Water extraction was
increased by Stg1 in the S35 background, whereas there was no effect in the R16
background. StgB modified the proportion of water extracted before and after anthesis in
the S35 background. While tillering and leaf area at anthesis were decreased by Stg1 and
Stg3 in the S35 background, there was no such effect in R16. By contrast, yield data
under fully-irrigated conditions showed higher tiller grain yield in Stg1, Stg2, and Stg3
ILs. While yield differences were mostly explained by harvest index (HI) variation, the
substantial yield variation unexplained by HI was closely related to TE in the S35
background (R2 = 0.29), and more so in the R16 background (R2 = 0.72), while it was
closely related to total water extracted in the S35 background (R2 = 0.41), but not in the
R16 background. These data indicate the potential for several stay-green QTLs to affect
traits related to plant water use and capture. However, they also show that these effects
depend on the interaction between genetic background and individual QTLs.","2011",,,"Functional Plant Biology","38","7","CSIRO Publishing",,"553-566",,,,,,,,,,,"TRUE",,"1445-4408",,,,,,"","http://dx.doi.org/10.1071/FP11073","http://scholar.google.co.in/scholar?as_q=Stay-green+QTLs+effects+on+water+extraction%2C+transpiration+efficiency+and+seed+yield+depend+on+recipient+parent+background&num=10&btnG=Search+Scholar&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publicatio","author",,"Australian Council for International Agricultural Research","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
