Yield Potential of some Candidate Confectionary Sunflower Cultivars in Menemen, Izmir Ecological Conditions
Öz
ABSTRACT: The main
objective of the study was to determine suitable confectionary sunflower
cultivars. The experiments were conducted in 2015 and 2016 growing seasons, in Randomized Complete Block Design with four
replications, on the experiment
field of Aegean Agricultural Research Institute (AARI) in Menemen conditions. Research materials were the candidate oilseed hybrid
sunflower varieties which were developed by sunflower breeding program of AARI
and oilseed hybrid sunflower varieties. Observations were
made on seed yield (kg/da),
1000 seed weight, hectoliter weight (g/l), seed oil
content, plant height (cm), head diameter (cm),
husk percentage (%), days to flowering date (days) and days to physiological
maturity (days), seed width (mm) and seed length (mm). According to two year results of this study
statistically significant differences were found in all traits among the
varieties in Menemen - Izmir (Turkey)
conditions. The
highest yield obtained from Cigdem, ETAE-NGL, Ege Günesi as 637, 629 ve 620 kg/da respectively in 2015. Whereas, the highest yield obtained from Cigdem and Ege
Günesi with 592 kg/da and 586 kg/da respectively in 2016. According to the
results of combined mean yield for two years (2015 and 2016) the highest yield
obtained from Cigdem and Ege Günesi as 614 and 603 kg/da respectively. Increase in sunflower production
could be possible by the expansion of acreage, giving importance to the second
crop agriculture, and beside those the high-yielding varieties need to be
planted. Research results indicated
that in terms of the yield and some quality characteristics of Ege Günesi is a
promising candidate variety for confectionary sunflower production in Turkey.
