“…This dilemma does not exist unless there is genotype x soil salt concentration interactions, e.g., where the highest yielding genotypes at high salinity yield comparatively poorly at lower salinities. Such interactions are common in comparisons between limited numbers of genotypes in many species (AYERS et al, 1952;BERNSTEIN et al, 1974;BOLE & WELLS, 1979; RI-CHARDS et al, 1982) and are likely to be more common in breeding programs for salinity resistance where large numbers of genotypes are tested.…”

Saline soils are typically very patchy in their salinity. The yield of crops growing on them is similarly patchy. This paper argues that because most of the yield from such soils comes from the least saline areas, the best breeding strategy for improving the overall yield of crops growing on them is to select for high yield on non-saline soils. This conclusion derives from comparing the effects that four different breeding goals, namely: (1) a 10% increase in yield on non-saline soils, (ii) a 20% increase in the threshold salinity that first reduces yield, (iii) a doubling of yield at an electrical conductivity of the saturation extract (EC,) of 20 dS/m and (iv) a combination of (i) and (iii), would have on total yield. The effects of achieving these goals in barley, common wheat, durum wheat and triticale in fields exhibiting different salinities are predicted from actual yields of these species grown on different salinities in the field.

“…In general, barley (Hordeum vulgare L.), grown for grain, tolerates root-zone salinity better than corn, wheat, oats, and other cereals (Marshall 1941;Ayers et al 1952;Ballantyne 1962;Saini 1972;Bernstein 1974;Bole and Wells 1979;Fowler and Hamm 1980;Bresler et al 1982;Maas 1986;Francois and Maas 1999). Barley seeded in severely saline soils tends to produce some grain even from rather deformed plants, which explains why barley forage production suffers more than grain production in saline environments (Hassan et al 1970;Maas and Hoffman 1977).…”

. 2005. Emergence, height, and yield of canola and barley grown in saline root zones. Can. J. Plant Sci. 85: 815-827. The salinity tolerance of a crop relates to its inherent ability to yield economic product as root-zone salinity increases. Barley (Hordeum vulgare L.) ranks as one of the more salt-tolerant of the annual cereal grain crops, but producers seek a salt-resistant, non-cereal grain crop as an agronomic alternative for saline fields. Could canola (Brassica napus L.) serve as this alternative? Two greenhouse tests were conducted to determine the inherent crop responses of three canola cultivars (Quantum, Hyola 401, InVigor 2573) to saline rooting media compared with that of Harrington barley. These crops were grown in sand tanks flushed four times daily with solutions dominated either by chlorides with salt concentrations measuring from 1.4 to 32 dS m -1 or by sulphates from 1.6 to 27 dS m -1 . In the Cl-test, the rate of emergence and the emergence time of the Quantum plants lagged those for Hyola and Harrington. In the SO 4 -test, these measures for the InVigor plants equalled those for the Hyola, but lagged those for Harrington. Relative crop height at harvest did not differ among the test crops in either test. Crop grain yields relative to the salt-free production analysed by the modified-discount equation resulted in Cl-solution tolerance indices of 11.0, 14.3, and 12.6 for Harrington, Hyola, and Quantum and SO 4 -solution indices of 11.4, 15.6, and 16.7 for Harrington, Hyola, and InVigor, respectively. Covariance analyses based on paired t-tests confirmed the conclusion that the salinity tolerance of the canola cultivars equalled that of Harrington barley.

Forty two wheat (Triticum aestivum L) cultivars screened for their relative salt resistance raising seedlings in halfHoagland solution (control) salinized with NaCl and maintained at 4, 8, 12 and 16 dsm-1 showed a wide range of salt resistance. The growth response to salinity, judged by the shoot and root lengths, ranged from a stimulation in the case of some cultivars at lower salinity levels (4 and 8 EC) to a severe suppression in most of the cultivars at higher levels (12 and 16 EC). It was further observed that the shoot growth was often suppressed more than the root growth with this a level of 12 EC also found to be critical for most of the cultivars except HD-2160 which showed good stand even at a salinity level of 16 EC. Based on these observations, cultivar IWP-72 of the 42 cultivars tested was found to have the maximum sensitivity to salt stress whereas cultivar HD-2160 showed highest salt tolerance. The remaining 40 cultivars fell between the two extremes and were categorized into salt-sensitive, moderately salttolerant and salt-tolerant groups exhibiting more than 60% , 40-60% and less than 40% reduction respectively in shoot length at 12 EC dsm-1 over control.
