Sweet sorghum (Sorghum bicolor L. Moench) is one of the most important cereals in the world. It contributes significantly to food security, sustainable agriculture, and renewable energy production as a low input crop. It is also grown for its sugar, bioenergy, human food, and livestock feed with high seed yield and biomass. The objective of this study was to evaluate the variation in seed yield and related traits, including thousand seed weight (TSW), seed yield (SY), seed length (SL), and width (SW) of the F3 sweet sorghum population (183 genotypes and two parents) in two different locations in Türkiye namely, Antalya (lowland) and Konya (highland). The results revealed that TSW ranged from 12.03 to 48.25 g with an average of 21.57 g in the lowland and 11.75 to 27.30 g with a mean of 20.43 g in the highland. The highest average value of SY was recorded as 3469.6 kg ha-1 in highland and 2435.1 kg ha-1 in lowland. The average SL value was identified 3.64 and 3.83 mm for lowland and highland, respectively, with a genotype-environment interaction was insignificant. The two locations average value of SW was 2.89, ranging from 2.07 (210) to 4.13 mm (271) and the highest value was identified in the genotype 20 (2.95 mm) in highland. The combination of the results from both locations indicated that the highest values of TSW, SY, SL, and SW were observed in genotypes 348 (34.98 g), 109 (4346.6 kg ha-1), 275 (4.36 mm), and 345 (3.38 mm), respectively. An important environmental variation was also observed in TSW, SY, SL and SW. The study showed a significant and positive correlation with a value of 0.32 between SW and SL, as well as a comparatively lower positive correlation of 0.14 between SW and TSW. Our results demonstrated the importance of the influence of the environment on different genotypes, thus enabling assessment and the efficient use of sorghum.
