Abstract
Prior knowledge on micronutrient within rice grain plays a vital role in providing information in selecting candidate parents that would facilitate biofortification through conventional plant breeding strategy. In this study, elemental analysis of Philippine traditional rice varieties and five elite lines was performed using Scanning Electron Microscope with Energy Dispersive X-ray Spectroscopy (SEM/EDX). From the initial 146-TRV that were used in this study, three were found high with micronutrients, the Fesl2, San Juan and Sinampan. The Fesl2 contains 7.22 g/kg of calcium and 9.71 g/kg of magnesium, while San Juan contains 16.74 g/kg of potassium and Sinampan contains 9.51 g/kg of phosphorus; MSR16WS-SI-28 of 5.52 g/kg of Magnesium and MSR16WS-SI-97, 1.15 g/kg of phosphorus with 3.64 g/kg of Ca, 4.08 g/kg of Mg, 2.26 g/kg of K. Based on elemental analysis in comparison with the micronutrients of the elite lines, three Philippine traditional rice varieties contains high amount of Ca, Mg, P, K. Screening of the micronutrient contents on the approx 15,000 Philippine traditional varieties is very important to identify the candidates as parent for breeding and ultimately for rice improvement using proper breeding strategy.
