Studies on the germination of Hordeum jubatum seeds indicate that they were highly tolerant of salinities up to 1.0%, with little reduction in germination. Each increase in salt concentration did, however, delay the time of germination. Seedling growth proved to be more sensitive than germination to salinity stress, with newly germinated plants showing a decrease in size with each salinity increment. Results of growth studies were similar to those in germination tests; plants decreased in size with decreased osmotic potential of the salt solution. The germination stage and later periods of active growth were nearly equal in their ability to withstand salinity stress.

Cowpea is a leguminous and versatile crop which provides nutritional food for human consumption. However, salinity unfavorably reduces cowpea seed germination, thus significantly decreasing cowpea production. Little has been done for evaluating and developing salt-tolerant cowpea genotypes at germination stage. The objectives of this research were to evaluate the response of cowpea genotypes to salinity stress through seed germination rate and to select salt-tolerant cowpea genotypes. The seed germination rates under nonsalt condition and salinity stress (150 mm NaCl) were evaluated in 151 cowpea genotypes. Four parameters, absolute decrease (AD), the inhibition index (II), the relative salt tolerance (RST), and the salt tolerance index (STI) were used to measure salt tolerance in cowpea. The results showed that there were significant differences among the 151 cowpea genotypes for all parameters (P values <0.0001). The AD in germination rate was 5.8% to 94.2%; the II varied from 7.7% to 100%; the RST ranged from 0 to 0.92; and STI varied from 0 to 0.92. A high broad sense heritability (H2) was observed for all four parameters. High correlation coefficients (r) were estimated among the four parameters. PI582422, 09–529, PI293584, and PI582570 were highly salt tolerant at germination stage. In addition, genotypes from the Caribbean and Southern Asia exhibited better tolerance to salinity, whereas those from Europe and North America were the most salt-susceptible.

Abstract This chapter reviews recent progress in the fundamental understanding of maize salt tolerance and the advancement of molecular breeding for salt-tolerant maize. Great progress has been made towards the molecular understanding of maize salt tolerance in recent years. Nevertheless, the breeding of commercial salt-tolerant maize hybrids remains challenging. Some issues that may facilitate maize molecular breeding for combating salinity stress are enumerated.
