“…A CGMS line, COSF6A and a multi-head restorer line, IR6 were crossed and designated as CSFH 12205 during 2012 at the Department of Oilseeds, TNAU, Coimbatore. Based on the performances in preliminary (Kharif 2012 andRabi 2012-13) and advanced hybrid yield trials (Kharif 2013 andRabi 2013-14) in station, this hybrid was promoted to Multi-Location Trial during 2014-2015 followed by Adaptive Research Trials (2015-2017. Simultaneously this hybrid was also tested in All India Coordinated Trials (2014Trials ( -2016 and On Farm Trials (2017).…”

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. Nonlodging hybrid COH 3 having moderate resistance to necrosis, leaf spot and powdery mildew diseases.

“…It offers potential for its cultivation to boost oilseed production. Sunflower hybrid development is gaining significance, based on its highly self-fertile, stable, high yielding and uniformity under different climatic conditions (Manivannan et al, 2017). Hybrid variety has some desirable advantages viz., faster growth, adaptation to stress, higher yield, and disease resistance.…”

The present study aimed to assess the high-yielding sunflower hybrids responding to various fertilizer levels. The experiment was conducted . with treatments that includes five genotypes in factor A (H1: COH 3, H2: DRSH-1, H3: KBSH-74, H4: KBSH-44, and H5: CO 2) and three fertilizer levels in factor B (F1: 50 percent RDF, F2: 100 percent RDF and F3: 150 percent RDF) in a three replications factorial randomized block design The study revealed that plant height and days to maturity of sunflower showed significant differences among the hybrids and different levels of fertilizer. Days to 50 per cent flowering significantly differed among the hybrids and not by the NPK level. The newly developed sunflower hybrid COH 3 recorded a higher yield (2194 kg ha-1) with high oil content (39.8 percent) and oil yield of 875 kg ha-1. Hybrid COH 3 registered a higher gross return of Rs. 70,208/- per ha with a net return of Rs.28,202/- and a cost-benefit ratio of 1.60. Among fertilizer levels, the 150 percent RDF recorded the highest yield, which was on par with the 100 per cent RDF. In monetary terms, rupee return per rupee investment was greater than 100 percent. As a result, in the Tamil Nadu region, sunflower hybrid COH 3 cultivation with 100% fertilizer, i.e., 60:90:60 kg NPK ha-1, was shown to be economical with better oil yields.
