As a result of the sunflower breeding studies carried out at the Trakya Agricultural Research Institute Directorate, Edirne
location, the sunflower variety was developed and submitted for registration. In the registration trials, yield, oil rate, oil
yield, imazamox (40g/l) resistant and morphological observations as a result, it qualified to be a variety and was registered
in 2024 with the name “1931 CL”. As a result of sunflower registration yield trials established in different regions of
Türkiye, the average yield of “1931 CL” variety was 2306 kg/ha, while the highest yield value was 3486 kg/ha grain yield.
According to the results of the experiment, flowering period of the varieties was 54-74 days, physiological maturity 88-106
days, plant height was 143-186 cm, and head diameter was determined in the range of 13-20,3 cm. In terms of technological
characteristics, oil ratio was determined in the range of 36-42,4%. In phytotoxicity observations, although the plants were
light green (2) and yellow green (3) when the first application was done one week after the first application, it was observed
that the harmful effect of imazamox (40 g/l) completely disappeared in the second week. Certified seed production of our
“1931 CL” sunflower variety; which was registered in 2024, was produced as of 2025 and offered to our farmers.
