Abstract: The present study was carried out in Kharif 2018 to study the variability in ten different traits among the sunflower genotypes. From the study it is clear that the magnitude of genotypic coefficient of variation was less than phenotypic coefficient of variation for all the trait studied. Maximum GCV recorded was 25.17 percent for oil yield and lowest of 3.11 percent for days to maturity. The maximum heritability recorded for oil yield (99.86%) and lowest for seed yield per hectare (16.25%). Similarly genetic advance observed highest for oil yield with 99.62 percent and lowest for test weight with only 0.48 percent and genetic advance over mean was more (51.81%) for oil yield. The correlation analysis depicted that two traits shown significant positive correlation with yield per hectare basis.
