Its essential to perform agronomic evaluations under farmers fields condition to select the best promising varieties and hybrids before releasing. A three replicates RCBD experiment was conducted using the recent promising sunflower hybrid (CMS19*R-1031) along with Uroflor, Allstar , Farrokh, SHF80-90 hybrids , Armaviresky cultivar and two open pollination populations in Pasargad and Marvdasht (Fars prvenice) in 2010. Each plot was consisted of four rows with 10.5 m length. Row spacing was 60 cm and plants were 25 cm apart on rows. Morphological and agronomical traits were recorded during growing season. The grain yield and 1000 seeds weight were measured based on a 6.6 m2 harvesting area consisted two middle rows of each plot with 5.5 m length. Determination of oil perecentage was conducted in oilseed research Department (Seed and Plant Improvement Institute). Simple and combined data analysis and comparisons among mean for some important traits were made using MSTATC software. Data simple analysis revealed significance of different genotypes for grain yield along with other parameters in both locations ( 1 and 5 for Marvdasht and Pasargad, respectively). CMS19*R-1031 and Armaviresky had the highest grain yield with 3662 and 3633 kg/ha in Pasargad and Marvdasht, respectively. Combined data analysis showed that the grain yield parameter is affected by location and variety, as well as location * variety interaction. The above hybrid was the outstanding genotype for the grain yield in Pasargad area based on data combined analysis. Key words: Sunflower, Hybrid, Yield
