Analysis of Genetic Differences in fatty Acids and Oil Contents among Brassica juncea

What is it about?

The experimentation was steered to assess erraticism among 188 Indian mustard genotypes owing to assorted biochemical parameters viz., palmitic, oleic, linoleic, linolenic and erucic acids accompanied by oil composition. Location of Study: Experiment was carried out at Department of Genetics and Plant Breeding, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, India Results: Analysis of variance designated the presence of considerable extent of variation among premeditated Indian mustard genotypes which advocate better promises for their enhancement. Genotypic and phenotypic coefficient of variation was investigated to be higher for oleic acid pursued by erucic and palmitic acids. Erucic, oleic, palmitic, linoleic and linolenic acids had determined heritability and genetic advance. Significant negative correlation of erucic acid was recognized with palmitic, oleic, linoleic and linolenic acids. Genotypic and phenotypic path coefficient analysis had the higher positive direct effect of palmitic acid on erucic acid, while highest negative direct effect on erucic acid was demonstrated by linoleic, oleic, linolenic acids and oil content. Genetic deviation employing Euclidean distance cluster congregated the genotypes into eighteen diverse groups. Amongst entirely considered biochemical strictures, erucic acid was investigated to be low in 9, modest in 57 and higher in 122 genotypes. In group investigation of qualitative parameters, extreme inter cluster
