الملخص

This study was conducted at two locations, University of Gezira farm (UGF) and Rahad Research Station Farm (RRSF), Agricultural Research Corporation, Sudan in winter season of 2018/2019 to study the genetic variability, heritability in broad sense, genetic advance and character association of the tested sunflower hybrids. A randomized complete block design with four replicates was used. Data were collected on days to 50% flowering, plant height, head diameter, head weight, number of seed per head, percentage of empty seeds, 1000seed weight (g), seed yield per plant (g), seed yield (Kg/ha), oil content (%) and oil yield (kg/ha). Phenotypic (PCV) and genotypic (GCV) coefficient of variation, heritability in broad sense (h2B), genetic advance (GA), genetic advance as percentage of mean (GA%) and correlation coefficient were estimated. Hybrids exhibited highly significant difference for traits studied in both locations except for oil content) indicating the presence of a wide genetic variability. Results revealed that the highest seed and oil yield were given by Opera hybrid (1956 kg/ha and 724.6 kg/ha, respectively) in UGF. (1701 kg/ha and 613.6 kg/ha), respectively in the combined over the two locations), whereas the highest seed and oil yield in RRSFF obtained by Supersun Hybrid (1659 kg/ha and 519.3 kg/ha, respectively). Phenotypic and genotypic coefficients of variation were highest for empty seed, seed yield per plant and seed yield. High heritability (˃ 61%) estimates were recorded for plant height, number of seed per head, head diameter, days to 50% flowering and head weight. High heritability with high genetic advance as percentage of mean were recorded for plant height and head diameter. Seed yield was positively and highly significantly correlated with seed yield per plant (0.97**), oil yield (97**) and head weight (96**). Through this study it could be recommended that Opera hybrid can be grown under irrigated conditions in central Sudan.
