West Sumatera Brown Rice Resistance to Fe

Indra Dwipa, Irfan Suliansyah, Etti Swasti

Abstract

Brown rice is favored nutritious rice consumed by urban people whole the world as carbohydrate substitutes. This rice is appropriate for an urban community that concerns to a healthy lifestyle and diabetes people as the main staple food.  One indicator of superior brown rice is resistant to abiotic stress, such as Fe. Fe is one of the main problems in cultivated land in Indonesia. The study aimed to study the West Sumatera brown rice resistance to Fe stress. West Sumatera belongs to the one province in Indonesia that can supply 2.5% of Indonesia rice requirement or 2 million tons in 2017. The research was conducted in the shade net house of Faculty of Agriculture, Andalas University, Padang, West Sumatera, Indonesia, from October 2017-January 2018. A completely randomized design was used in the assay and replied 3 times. 15 brown rice genotypes that consisted of 13 brown rice (Surian, Padi Ladang, Talang Babungo, Sungai Abu, Gunung Pasir, Perbatasan, Kekuningan, Pido Manggih, Siarang, Padi Telur, Sikarujuik, Jorong Mudiak and Teluk Embun) and 2 black rice genotypes (Sariak Alam Tigo and Solok) were used in the research. 2 genotypes (IR-42 and IR-64) were used as the control. The result showed that 5 West Sumatera brown rice genotypes were tolerant to Fe stress, Talang Babungo, Perbatasan, Kekuningan, Siarang, and Black Rice Solok. The result also showed that Fe affected the height of the plant, length of root, dry grain weight, and production of grain per pot. Black Rice Solok was the best genotype for grain production per hectare (3.3 ton).
