Name CQL18 (QTL ACCESSION {description)
Synonyms (1) CQL18-RELRTLG
TO TERM {descriptionTO:0000516 (relative root length)
Trait Namerelative root length

Type QTL
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
Description 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.
