TAILIEUCHUNG - Determining combining ability in sunflower (Helianthus annuus L.)

The experiments, involving 25 sunflower hybrids, were conducted in 3 locations in 2000 and 2001. These hybrids were evaluated for 4 important yield components (seed and oil yields, oil content and hull ratio) by combining ability. The experimental design was a randomized complete block design with 3 replications. | Turk J Agric For 29 (2005) 243-250 © TÜB‹TAK Determining Combining Ability in Sunflower (Helianthus annuus L.) Yalç›n KAYA Trakya Agricultural Research Institute, PO BOX: 16, 22100 Edirne - TURKEY Received: Abstract: The experiments, involving 25 sunflower hybrids, were conducted in 3 locations in 2000 and 2001. These hybrids were evaluated for 4 important yield components (seed and oil yields, oil content and hull ratio) by combining ability. The experimental design was a randomized complete block design with 3 replications. Based on specific combining ability (SCA) analysis, the hybrid 2453-A x 2644-R was determined as the best hybrid in the experiment. The female lines 2453-A and 0704-A and the male lines R-1001 and 2644-R had higher seed and oil yield performances in this research. However, the 2644-R and 2280-R restorer and HA89-A and BAH-8-A female lines had the highest oil percentages. Among the parental lines, the 2453-A female and 2644-R male had the best GCA (general combining ability) and SCA effects based on the 4 yield traits in the experiment. Additionally, the HA89A and R-1001 lines were selected also to test combining ability using 2 testers for both female and male lines in future breeding programs.

Kombinasyon Kabiliyetinin Belirlenmesi Özet: Deneme 25 ayçiçe¤i hibridinden oluflmufl ve 2000 ve 2001 y›llar›nda 3 lokasyonda, tesadüf bloklar› deneme deseninde 3 tekerrürlü olarak kurulmufltur. Araflt›rmada ayçiçe¤inde 4 önemli verim ö¤esi olan ya¤ ve tane verimi, ya¤ ve kabuk oran›nda kombinasyon kabiliyeti analizleri yap›lm›flt›r. Araflt›rmada, en yüksek tane ve ya¤ verimi 2453-A ve 0704-A ana ve R-1001 ve 2644R baba hatlar›, en yüksek ya¤ oran› da HA-89 ve BAH-8-A ana ve 2644-R ve 2280-R restorer ebeveyn hatlar›yla yap›lan melezlerde ölçülmüfltür. Yap›lan kombinasyon kabiliyeti analizleri sonucunda; 11. (2453-A x 2644-R) .
