Mapping of quantytative trait loci for high iron ang zinc content in polished rice (Oryza sativa L) grain and some agronomic traits using simple sequence repeats markers

Abstract

Iron and zinc deficiency occurred especially in the poor region of the world causing significant loss due to death, sickness, and decreasing productivity as and life quality. Genetically increasing the iron and zinc content of rice grains is an efficient and effective way to overcome the iron and zinc deficiency problem. Mapping of QTLs (Quantitative Trait Loci) controlling high iron and zinc content in polished rice grains to get markers for Molecular Assisted Breeding (MAS) is prospective to be done since iron and zinc content are quantitative traits that highly affected by environment and its measurement is still costly. Study on polished rice as ste state of people use for their consumption would give more applicable result and study on agronomic and yield related traits would be helpful to incorporate those traits in breeding activity. Simple Sequence Repeats (SSR) markers were used in this study.
