Abstract

                                The efficiency of selection mainly depends on the direction and magnitude of association between yield and its components. Knowledge on the strength and type of association is an important pre-requisite for the formulation of breeding procedure. The material consisted of twenty four genotypes were raised to evaluate the performance for important characters in sunflower. The experiment was laid out in a randomized block design with two replications during rabi / summer 2005-2006 at Department of Oilseeds, Center for Plant Breeding and Genetics, TNAU, Coimbatore. Each genotype was sown in two rows of 6m length with a spacing of 60 x 45 cm.Oil content in the seeds of selected plants was determined with the help of Oxford 4000 Nuclear Magnetic Resonance (NMR) Spectrometer

Key words : Correlation and path analysis, genotypes, replications, Nuclear Magnetic Resonance
