What is it about?
In the present study, a RIL population consisting of 148 lines, derived from a cross between IR29 (salt-sensitive) and Pokkali (salt-tolerant), was used to identify new QTL for salt tolerance and investigate the relationships between salt stress caused injury and the changes in different physiological and morphological traits at the seedling stage.

Why is it important?
Three QTL for salt injury score (SIS) were located on chromosomes 1, 4 and 12, all being closely related to the long-distant Na+ transport from roots to shoots. These QTL showed additive effects, thus can be effectively used in the breeding programme to pyramid various tolerance genes.
