Estimates of phenotypic correlation coefficients for grain iron, zinc, protein and thousand kernel weight in RILs of WH542 × Synthetic derivative in rabi 2012–2013 and 2013–14 grown at ICAR-IARI, GBPUA&T, and Pusa Bihar.
Fig 4.
Linkage groups of wheat showing QTLs identified for grain iron, zinc, protein and thousand kernel weight by CIM in 286 RILs of the cross WH542 × Synthetic derivative.
QTLs were designated using Q as abbreviation for QTL, and abbreviation of the trait name in upper case (GFe, GZn, Gpc, QTkw; Grain iron concentration, Grain zinc concentration, Grain protein content, Thousand kernel weight respectively) with a full stop, followed by Institute name (iari) in lower case and chromosome number on which the QTL is found to be located. The QTL peaks have been shown on the linkage groups and the confidence intervals by the bars (blue color for GFe, orange color for GZn, green color for Gpc and red color for GTkw).
