Determination of Yield and Quality Characteristics of Tribenuron Methyl Group Sunflower Genotypes Newly Developed

Abstract

The present study was conducted to determine the yield and quality characteristics of oil sunflower genotypes as candidates for registration under Konya and Karaman conditions, in 4 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, the diameter of the tray, the thousand seed weight, seed moisture, seed yield, oil content, and oil yield were found to be statistically significant. The number of flowering days of the genotypes was found to be 64.5-60.8 days (H412; P63LLE113), the number of days to physiological maturity was 113.9-110.3 days (H412; P63LLE113), plant height 169.0-164.6 cm (M94S35; P63LE113), head diameter 20.9-17.3 cm (H412; P63LLE113), thousand-seed weight 60.3-47.4 g (H408; P64LE119), seed moisture 7.8-5.9 % (H408; P63LE113), seed yield 43.6-43.2 t ha-1 (H412; P64LE119), oil content 44.2-41.8 (H412; M94S35), and oil yield 19.2-17.0 t ha-1 (H412; P63LE113). The study showed that high yields could be achieved by using newly-developed hybrid sunflower genotypes in the conditions in the region. According to the averages of the location, it can be argued that the H412 hybrid that has high seed and oil yield can be successfully grown in regional conditions.
