Abstract
An experiment to develop higher-yield sunflower hybrids, comprising seven single and seven double cross selected plants planted at the Agriculture Research Institute, Tarnab, Peshawar, Pakistan, was performed during August 2001. Hybrid selection data included 1000 grain weight, number of grains per head, number of filled grains per head, number of filled versus unfilled grains per head, harvest index and grain yield. Recorded data revealed positive correlations between all the analyzed grain yield characters. Two hybrid entries (TF-7 x TF-11) and (TF-7 x TF-22)x(TF-17 x TF-18) showed superior grain yield and yield related characters recorded in single and double cross hybrids. This study demonstrated that diversity of grain yield characters in this study can be use as the effective selection of promising and superior double cross sunflower hybrids.
