Sunflower COH 3: A high yielding and high oil content sunflower hybrid for Tamil Nadu. Electronic Journal of Plant Breeding

Abstract

Development of hybrids in sunflower are increasing recently since, the hybrids are highly self-fertile, stable, high yielding and more uniformity under different climatic conditions. Sunflower hybrid COH 3 (CSFH 12205) have been released during 2018 which is suitable for Tamil Nadu with the duration of 90-95 days. COH 3 hybrid was tested in Station Trials, Multi-Location Trial, AICRP Trials, Adaptive Research Trial and On Farm Trials. It performed well both under rainfed and irrigated conditions. Sunflower COH 3 recorded an average yield of 2214 kg/ha which is 20.5 per cent over Sunbred 275 and hybrid having the yield potential of 2384 kg/ha during Kharif season and 2043 kg/ha during Rabi. COH 3 hybrid possessing high oil content around 42 per cent as compared to check hybrids viz.,Sunbred 275 (38%) and Hybrid CO 2 (39 %) and high volume weight of 47 g/100ml. This hybrid recorded the highest oil yield of 716 kg/ha which is 26.7 and 20.1 per cent over Sunbred 275 (565 kg/ha) and CO 2 Hybrid (596 kg/ha), respectively. Non-lodging hybrid COH 3 having moderate resistance to necrosis, leaf spot and powdery mildew diseases.
