Abstract:

This research was conducted to determine the yield and quality characteristics of oil sunflower genotypes as candidates for registration under Konya and Karaman conditions, in four replications according to the “Random Blocks Trial Design”. The differences between the cultivars used in both locations of the study in terms of the number of days to bloom, the number of days to physiological maturity, plant height, the diameter of the head, the thousand seed weight, seed moisture, seed yield, oil rate, and oil yield were found to be statistically significant. The number of flowering days of the genotypes was found to be 65.6-60.6 days (H194; P63MM54), the number of days to physiological maturity was 116.9-109.0 days (Tunca; P63MM54), plant height 172.0-143.3 cm (Tunca; H249), head diameter 18.8-15.9 cm (H250; P63MM64), thousand-seed weight 43.4-54.2 g (H250; Gibraltar), hectoliter weight 32.3-30.3 kg (P63MM54; H194), seed moisture 7.1-8.4 % (H250; P63MM54, Gibraltar), seed yield 4.37-3.82 t ha-1 (H194; H249), oil rate 47.8-42.9 % (H250; H55), and oil yield 2.04-1.64 t ha-1 (H250; H249). According to the averages of the locations, it can be argued that the H194, H250, H55, and H5 hybrids that have high seed and oil yield can be successfully grown in regional conditions.
