Abstract: A field experiment was conducted at MARS, University of Agricultural Sciences, Dharwad, during Kharif 2013 to find out the physiological basis of yield variations in Sunflower genotypes. The experiment consisted of 12 genotypes laid out in randomized block design with three replications in medium black soil under rainfed conditions. The results of the investigation revealed a wide variation among the genotypes with respect to various morphological, growth, phenological, biophysical, biochemical, yield and yield components. Among the genotypes KBSH-44, DSFH-2 and PAC-8699 exhibited superiority over rest of the genotypes in yield by giving a better response to most of the yield contributing characters, such as more number of leaves and higher distribution of dry matter into reproductive parts, higher LAI, LAD and CGR at later growth stages. Higher chlorophyll content, photosynthetic rate, stomatal conductance, test weight and higher seed yield. However it was noted from the present study that hybrids, DSFH-2 and S-293 recorded higher oil content. It was inferred from the present by considering the relative performance of genotypes with respect to various characters. The hybrids KBSH-44, DSFH-2 and PAC-8699 were more efficient because of improved morpho-physiological parameters.
