Abstract

Flax is one of the oldest utilitarian plants that have been grown for fibre as well as an oilseed crop. The species has been recognized as an excellent source of micronutrients, dietary fibre, protein, vitamin B1, lignan, and essential fatty acids, namely linoleic and á-linolenic acids. This study was to determine the effect of different concentrations of NaCl on Physio-Chemical parameters of different linseed genotype and the study was laid out in FRBD (4x9 Factorial), having three levels each of Nacl (100mM, 150mM and 200mM) and nine varieties viz., SHA1, SHA2, SHA3, SHA4, SHA5, SHA6, SHA7, SHA8 and SHA9, making a total of 36 treatment combinations with control, each replicated three times. NaCl affects the Chlorophyll content (mg/g), Carotenoids (mg/g), Proline (μg/g fresh w.t), Malondialdehyde (μmole/g fresh w.t). Whereas the the maximum Chlorophyll content, Carotenoids (mg/g), Proline (μg/g fresh w.t), is maximum was recorded in variety SHA7 Malondialdehyde (μmole/g fresh w.t)was found in minimum SHA3. Thus it shows that SHA7 genotype is more potential in saline soil. The research will provide useful leads in the planned development of linseed cultivars having increased salt tolerance.
