India Journal Article 2020 09 01 This study aims to evaluate the effects of season and spacing on growth patterns and seed yield performance of muskdana by estimating fixable and non-fixable components of genetic variances for diverse traits of economic significance and identification of highly divergent clusters of genotypes to exploit them in hybridization program. Radical scavenging activity of oil from muskdana seeds was also checked. The field experiment was conducted in two seasons , namely January to June (season I) and July to December (season II) with five spacing levels treatment 1, 2, 3, 4, and CIMAP of Abelmoschus moschatus. From the obtained results, it can be concluded that genotypes CIM-AM 22, CIM-AM 40, and CIM-AM 49 of A. moschatus showed greater potential in terms of yield. A. moschatus oil has also effective and powerful reducing power and exhibits significant radical scavenging activity which is comparable with standard antioxidants such as ascorbic acid, BHA, and BHT.
