Abstract

Rice (<i style="mso-bidi-font-style:normal">Oryza sativa </i>L.) is one of the important food crop and main source of nourishment for more than one half of the world population. Medicinal landraces like <i style="mso-bidi-font-style:normal">Navara </i>is highly nutritive and are rich in minerals like potassium, sodium, calcium, micronutrients, <i style="mso-bidi-font-style:normal">viz. </i>iron and zinc. The present investigation was carried out in the Department of Plant Breeding and Genetics at Agricultural College and Research Institute, Madurai during 2012–2014. High yielding released variety of Tamil Nadu used for standard check ADT 43 along with four different medicinal landraces of rice collected from different areas of Kerala and Tamil Nadu, <i style="mso-bidi-font-style:normal">viz.</i> <i style="mso-bidi-font-style:normal">Navara, Kavuni, Veeradangan</i> and <i style="mso-bidi-font-style:normal">Kathanellu </i>were used. By improving the strain of these traditional medicinal rice varieties, scientists hope to make it stronger to withstand the onslaught of climate and ensure higher output.
