“…Somaclonal variation and in vitro-induced mutagenesis can be used to create variability from which crop plants can be improved. Cell and tissue culture techniques have been used to obtain salt tolerant plants through two in vitro culture approaches: selection of mutant cell lines from cultured cells and subsequent plant regeneration (somaclones; Tal 1990Tal , 1993Tal , 1994Mandal et al 1999;Zair et al 2003;Gandonou et al 2006;Lu et al 2007;Queirs et al 2007) and in vitro screening of plant germplasm for salt tolerance (Arzani and Mirodjagh 1999;Dziadczyk et al 2003;Lee et al 2003;Wheatley et al 2003;Dasgupta et al 2008). Our recent work with durum wheat indicates that the response of in vitro selected genotypes was comparable with that of field-selected Table 2.…”

“…Field screening procedures in saline soils are confronted by spatial heterogeneity of soil chemical and physical properties as well as seasonal fluctuations in rainfall . Hence, many screening experiments for salttolerant genotypes were conducted either under in vitro (Barakat and Abdel Latif 1996;Arzani and Mirodjagh 1999;Dziadczyk et al 2003;Lee et al 2003;Dasgupta et al 2008) or under controlled environmental conditions (Kingsbury and Epstein 1984;Rawson et al 1988;Munns et al 2000;Mohammadi-Nejad et al 2008).…”

Salinity limits the production capabilities of agricultural soils in large areas of the world. Both breeding and screening germplasm for salt tolerance encounter the following limitations: (a) different phenotypic responses of plants at different growth stages, (b) different physiological mechanisms, (c) complicated genotype × environment interactions, and (d) variability of the salt-affected field in its chemical and physical soil composition. Plant molecular and physiological traits provide the bases for efficient germplasm screening procedures through traditional breeding, molecular breeding, and transgenic approaches. However, the quantitative nature of salinity stress tolerance and the problems associated with developing appropriate and replicable testing environments make it difficult to distinguish salt-tolerant lines from sensitive lines. In order to develop more efficient screening procedures for germplasm evaluation and improvement of salt tolerance, implementation of a rapid and reliable screening procedure is essential. Field selection for salinity tolerance is a laborious task; therefore, plant breeders are seeking reliable ways to assess the salt tolerance of plant germplasm. Salt tolerance in several plant species may operate at the cellular level, and glycophytes are believed to have special cellular mechanisms for salt tolerance. Ion exclusion, ion sequestration, osmotic adjustment, macromolecule protection, and membrane transport system adaptation to saline environments are important strategies that may confer salt tolerance to plants. Cell and tissue culture techniques have been used to obtain salt tolerant plants employing two in vitro culture approaches. The first approach is selection of mutant cell lines from cultured cells and plant regeneration from such cells (somaclones). In vitro screening of plant germplasm for salt tolerance is the second approach, and a successful employment of this method in durum wheat is presented here. Doubled haploid lines derived from pollen culture of F 1 hybrids of salt-tolerant parents are promising tools to further improve salt tolerance of plant cultivars. Enhancement of resistance against both hyper-osmotic stress and ion toxicity may also be achieved via molecular breeding of salt-tolerant plants using either molecular markers or genetic engineering.

Genetic variation is essential for crop breeding. In classical plant breeding programme, variation is generated by hybridization and selections are made from the resulting segregating generations. Induced mutagenesis can supplement hybridization or able to replace as a source of variability. Since, mutations bring about variation, they provide the ultimate basis for evolution of new forms, varieties or species. Induced and spontaneous mutations have played an important role in developing improved cultivars of various fruit crops as a supplementary method to conventional breeding. But, induced mutations also have well defined limitations in fruit breeding applications, but their possibilities may be expanded by the use of in vitro mutation techniques.

“…To evaluate the salt tolerance of selected and multiplied clones, plant samples were grown for 30 days on BM added with 0.75 mM NaCl or on the salt-free control medium, according to the method developed by Dziadczyk et al [6]. The increase of shoot fresh weight, expressed as relative growth rate [RGR: (ln Fwfinal − ln FWinitial) × 100/total days of growth (where total days of growth are 30 and FW is the fresh weight of the plants)], and proline content were measured in both experimental conditions.…”
