| The mutants also exhibited varied and wide impacts of saline water on
mineral contents of grains (Table 3). It is worth
mentioning that all the mutants showed higher protein content to respective
control varieties. However, Na content was comparatively less affected.
Interestingly, the salt tolerant mutant Bhp 12 was improved to HD 1553 in
mineral contents i.e. protein, P, K and Ca. It was however, inferior in
Mg content. In contrast, other salt tolerant mutant Bhp 19 was improved
to HD 2009 with regard to protein and K contents only. The salt tolerance
nature of these two mutants seems to be different. For instance, Bhp 12
looks to be Na-tolerant as it showed higher Na content. On the other hand,
mutant Bhp 19 may be considered Na excluder as it showed lower Na content.
