An investigation was carried out in the Department of Plant Breeding and Genetics at Agricultural College and Research Institute, Madurai with 13 parents and 40 hybrids of rice which were effected through Line x Tester mating design. Seven high yielding released varieties of Tamil Nadu viz., MDU 5, ADT 36, ADT 43, ADT 45, TPS 4, ASD 16 and one IRRI variety IR 72 were used as lines. Five medicinal landraces of rice collected from different areas of Kerala and Tamil Nadu viz., Navara, Chennellu, Kavuni, Veeradangan and Kathanellu were used as testers. Based on per se performance of single plant yield and number of productive tillers per plant, 12 hybrids were selected and analysed for six biochemical parameters viz., carbohydrate, protein, iron, zinc, calcium and magnesium contents along with their parents. The GCV and PCV (genotypic coefficient of variance and phenotypic coefficient of variance) were high for all the traits except for carbohydrate content. High heritability with high genetic advance was exhibited by all the nutritive traits while moderate genetic advance was exhibited by protein content.
