Abstract

Iron (Fe) is an essential micronutrient for rice growth which can be toxic in excess conditions. Identification of molecular markers related to iron toxicity tolerance is important for the development of tolerant rice varieties. We identified the STS markers associated with iron toxicity tolerance in a doubled haploid rice population. We screened the phenotype for forty-five lines derived from reciprocal double-crossing, i.e. IR54 / Parekaligolara // Bio 110 / Markuti in high Fe wetland rice field. We used STS markers for OsIRT1, OsIRT2, AtIRT1, OsNAS1, OsNAS2, OsNAS3, and OsFRO2. Data analysis used Tassel 3.0, in which the P-value <0.05 indicated that the STS marker was associated with the phenotypic response. The analysis showed three STS markers, namely OsIRT1, OsIRT2, and OsFRO2, associated with iron toxicity tolerance in rice. Keywords: Iron toxicity tolerance, rice, STS marker, OsIRT, OsFRO
