Abstract:Sixty F3 progenies of sunflower were evaluated in department of plant breeding and Genetics, College of Agriculture, University of Sargodha. Eight yield related phenological traits viz., seed yield head-1(SYP), days to flowering (DTF), days to maturity (DTM), oil contents (OC), 100-seed weight (100-SW), head diameter (HD), plant height (PH) and leaf area (LA) were analyzed for genetic variability, correlation to estimate association between traits and biplot analysis for genotypes by trait interaction. ANOVA results showed that all the F3 progenies had significant difference for all the traits studied. Coefficients of genotypic and phenotypic correlation showed that SYP had significant and positive correlation with DTM, DTF, HD, 100-SW and PH. Oil contents were negatively correlated with DTF, DTM, 100-SW. 100 seeds weight (100-SW) showed highly significant and positive correlation with DTF and DTM by genotypically while significant positive at phenotypic level. Progenies A-50 and A-58 were prominent due to their highest SYP and 100-SW and A-12 and A-26 had the highest HD and DTF while progeny A-30 had the lowest DTF and DTM and could be selected due to early maturing traits.
