Black Rice Anthocyanin Content Increases with Increase in Altitude of its Plantation

Abstract

Black rice is the most nutritious heirloom rice landraces. A G60 black rice variety was grown in both terai and hill region of Nepal at 79meters and 1360meter altitude from mean sea level in 2015. The important rice qualities such as total anthocyanin content, caryopsis color, Calcium, and iron content were analyzed. It was observed that the anthocyanin content of black rice increased significantly with increase in altitude of its plantation site. The increase in anthocyanin content may be due to favorable environment and environment genotype interaction. This finding also indicates that some other rice quality may also increase with an increase in altitude of its plantation.
