Description Dry mass (g) product is the dry weight of the harvested shoot part of plant.
Three completely randomized blocks containing all the lines were grown at the
same time. The hydroponic culture solution was salinized at 10 days after
planting, by slowly adding 5 M NaCl to the header tank of a recirculating pump
so that the concentration rose gradually to 50 mM over a period of about 24 h
and was maintained for 12 d, after which the concentration was increased to 100
mM for a period of 8 days. The shoots were then harvested, dried, weighed, and
extracted in 100 mM acetic acid for 2 h at 90°C. Sodium and potassium were
determined in the extract by atomic absorption spectroscopy (Unicam 919,
Unicam, Cambridge, UK). QTL analysis was performed using the marker regression
approach using the software package QTL Café. Associations between genetic
markers and traits were detected by single-marker ANOVA for each trait using
GENSTAT (P < 0.005).
