COMPARATIVE STUDY ON THE YIELD PERFORMANCE OF SUNFLOWER HYBRIDS UNDER AGRO-ECOLOGICAL CONDITIONS OF D.I.KHAN

Eight Sunflower Hybrids representing diverse genetic back ground were evaluated for achene yield, 1000- Achene weight, plant height, and oil percentage and protein contents at Agronomic Research Area, Faculty of Agriculture, Gomal University, D.I. Khan, Pakistan during spring 2005. Hybrids were found significantly different from one other for all the traits studied in the experiment Hybrids kg ha -1 Hysun-33 proved to be the best with maximum achene yield (2279.86 kg/ha) as compared to hybrids Sunbred-265 which gave achene yield of 1699 kg/ha. The highest 1000 achene weight was recorded from hybrid Hysun-33 while the remaining hybrids were at par with each other. Hysun-33 hybrid affianced tallest plants with 130 cm as compared to Sunbred-265 and Suncross-24 that were found shortest plants with 123 cm height each. Maximum oil contents value (41.24 %) was noted in Hysun-33 while minimum oil contents value (36.17 %) was obtained from Suncross-24. Maximum protein percentage (26.76 %) was observed in Hysun-33 which statistically at par with DK4040 (25.95 %).Minimum protein parentage (23.62 %) was shown by Suncross-24 which also at par with NK-212 (23.82 %) and sunbred-265 (23.73 %) (Oral, E and K- Kara, 189).
