Rice is sensitive to salinity stress at both the seedling and reproductive *** present study used 145 rice genotypes comprising of 100 landraces and 45 advanced breeding lines collected from different regions of *** genotypes were evaluated in hydroponics under control[electrical conductivity(ECe)~1.2 dS/m]and saline(ECe~10.0 dS/m)environments along with susceptible(IR29)and tolerant(FL478)*** stress susceptibility index for eight morphophysiological traits was *** of variance showed significant differences among the genotypes for all the parameters studied in control,stress and relative stress *** identified 3 landraces(Kuttimanja,Tulasimog and IET-13713I)as tolerant and 14 lines as moderately tolerant to salt *** correlations in the morphological(root and shoot lengths)and physiological traits(shoot Na^(+),Ca^(2+)and Mg^(2+)contents,and Na^(+)/K^(+)ratio)were observed under all the *** hierarchical cluster analysis grouped the genotypes into five clusters,among which cluster Ⅱ comprised salt-tolerant *** of Saltol region using 11 simple sequence repeat markers on 17 saline tolerant and moderately tolerant lines was *** AP3206F,RM10793 and RM3412b,located close to skc1 gene(11.23‒12.55 Mb),displayed diverse allelic variations and they were not related to the FL478 *** this region,tolerant lines like Kuttimanja,IET-13713I and Tulasimog have new *** a result,these lines may be suitable candidates for novel genomic regions governing rice salinity ***-tolerance ability of Kuttimanja,Tulasimog and IET-13713I was validated in two years in three salinity stress *** promising lines can be used in breeding programs to broaden the genetic base of salinity tolerance in rice,and it may help to dissect key genomic regions responsible for salinity tolerance.
