Morphology, yield, grain quality and minerals content (Fe and Zn) in white, brown and black rice lines

This study aims to determine the morphology, grain yield, grain quality, and minerals content (Fe and Zn) of white rice, brown rice and black rice lines produced by the Indonesian Center for Rice Research (ICRR). The research used 25 rice genotypes consisting of nine white rice lines, ten brown rice lines, four black rice lines and two check varieties (Aek Sibundong and Ciherang). The experiment was conducted in the Pusakanegara Experimental Station, Subang, West Java from January to April 2016. The experiment used a Randomized Completely Block Design (RCBD) with three replications. The results showed that three white rice lines yielded dry grain significantly higher than Ciherang (7.3 ton/ha) and four brown rice lines had grain yield significantly higher than Aek Sibundong (6.0 ton/ha). Four white rice and one black rice lines had high Fe content in endosperm (>15.0 ppm), while high Zn content (>25.0 ppm) was found in four white rice, two brown rice and one black rice lines. The lines that have high yield were not corelated by high Fe and Zn content, except for one brown rice line B13820E-MR-50-3-2 which had yield of 7.7 tons ha and a high Zn content (26.6 ppm).
