QTL underlying iron toxicity tolerance at seedling stage in backcross recombinant inbred lines (BRILs) population of rice using high density genetic map

Fe is a trace element considered to be essential for rice, and it drives several metabolic processes. toxicity occurs due excessive ions (Fe2+) which, disturb cellular homeostasis dramatically reduces the rice yield. A set of 118 BRILs made from cross japonica cv.’02428’ indica ‘Changhui 891’ was used with high density bin map constructed by using quality SNP identify QTL tolerance. As whole total 23 were identified various seedling traits, 3 under control phenotypic difference ranging 14.21% 62.46%, 11 stress 7.89% 47.39% 9 stressed/control ratio variance 9.17% 183.50%. LOD values 4.05 17.04 in control, 3.41 8.09 2.84 to131.63 stress/control ratio. Shoot length (SL), root (RL), shoot fresh weight (SFW), (RFW), dry (SDW), (RDW), estimate degree Many stable QTL, qSSDW-4, qSSDW-6, qRSDW-4 qRSDW-6 affecting SDW detected beside this some new qRSFW-1, qRRFW-10 qRRDW-1 successfully significantly contributing tolerance rice. The results current study indicated that these novel regions could transferred via markers assisted section pyramiding develop resistant lines
