Abstract

The genetic basis of relative salinity tolerance was studied at GERMINATION stage of RAPESEED (Brassica napus L.) cultivars at 0 100 and 200 mM NaCl salinity using a 6 parent F__1 DIALLEL. The parents were chosen to reflect the range of tolerance in a larger sample of over 20 varieties previously assessed for variability in salinity tolerance. Analysis of variance for each salinity level showed high significant genotypic differences for coefficient of velocity of GERMINATION (CVG) GERMINATION index (GI) and mean GERMINATION time (MGT) at control and for CVG GI MGT and GERMINATION rate index (GRI) at 100 mM NaCl salinity level. At 200 mM NaCl no significant differences obtained among genotypes. At 100 mM NaCl both additive and non-additive effects were significant with the prevalence of dominance gene action over additive effects. Recessive genes controlled tolerance in all traits examined. The estimated broad sense heritabilities were high while narrow sense heritability estimates were low indicating relatively high dominance gene effects. Analysis of combining abilities showed that both additive and dominance effects were important in genetic control of GERMINATION parameters at 0 and 100 mM NaCl. Since recessive genes governed tolerance the tolerant parent was one of the poorest specific combiners. Large heterotic combinations in some crosses and the existence of significant dominance effects suggested the potential of hybrid RAPESEED breeding for soils with salinity problem.
