The experiment was conducted at the Mama Arif Farm, opposite of Dada Bhaee Cement Factory Super Highway, under WRRI/NARC-(PARC) Research Field Station Thana Boula Khan, randomized complete block design (RCBD). The results revealed that sunflower hybrids showed diverse growth, seed yield and oil content performance; and Hysun-33 ranked 1 with 192 cm plant height, 5.89 cm stem girth, 16.75 leaves plant , 17.95 st 1 cm head diameter, 1213.30 seeds head , 69.46 g seed weight head , 59.31 g seed index value, 1904.50 kg ha 1 1 1 seed yield and 43.43% oil content.

However, the estimated area under sunflower crop Edible oil production is around 23 percent of the total for the year 2010-2011 was 448.40 thousand hectares, domestic demand and the country is facing severe providing basic seed production of 643 thousand tons shortage of this important commodity. Consequently, with cooking oil production of 244 thousand tons [1]. a huge quantity of edible oil is imported and the Number of two varieties of sunflower were cultivated, requirement is increasing every year. Local production one for use of oilseed manufacturing and second for non of edible oil is 662 thousand tons against the domestic oilseed for house and bird food for commercial purpose. demand around 2900 thousand tons [1]. The Sunflower Variety oilseed which may be linoleic or oleic are mainly fulfills the gap of need and provide safe oil and it is well dull or dark in color of seed having slim hull which adapted to agro-ecological conditions of Pakistan. The adheres to the kernel. Other variety of oil seed, persist crop was sown on an area of 352.89 thousand hectares 38% to 50% oil and approximately 20% of protein. of 513 thousand tons and oil production of 195 thousand
