Comments Relative root length was assayed to evaluate phenotypic variation in Aluminium tolerance. It was measured as the ratio of the maximum root length under Aluminium stress divided by the maximum root length in the control. The maximum root length was calculated as an average of the greatest length and the second greater length root of each plant. It was measured for the parents and the entire population lines after stress for 4 weeks. The QTL for Al tolerance was identified by conditional QTL mapping based on the phenotypic means of relative root length measured at the 4th week of stress. The conditional means of RRL were obtained by the mixed-model approach. The variation in RRL at the 4th week after stress across the population, and the molecular markers linked to the putative QTLs, were analyzed by Qgene. The threshold for declaring a putative QTL for Al tolerance was LOD >2.4. It is an epistatic loci for Relative root length QTL (feature accession ID: CQL6) on chr-5. It contributes about 14% of total variation.
