“…Field trials (Ahmad & Abdullah, 1979: Barnes & Peele, 1958: Bernstein & Ayers, 1951: Bouaziz, 1980: Levy, 1992: Paliwal & Yadav, 1980 and outdoor pot trials (Levy et al, 1988) were primarily focussed on NaCI (or mixed salt) effects on tuber yields. Greenhouse pot trials were used to examine genotype salinity tolerance under NaC1 or mixed sodium salt irrigation solutions and were based on either tuber yield (Bruns & Caesar, 1990, relative reduction of foliage dry weight (Bilski et al, 1988) or haulm fresh weight (Naik & Widholm, 1993) but not yield.…”

SummaryThree in vitro bioassays (single-node cutting, root tip segment and microtuberization) gave similar results in ranking the salinity (NaCI) tolerance of several potato genotypes (Solanum spp.) and were verified by tuber yield criteria in a field lysimeter trial with salinized irrigation water. Salinity stress consistently depressed growth in the single-node cutting and root tip segment bioassays, reduced microtuber yield in the microtuberization bioassay and decreased tuber yield in field lysimeters. The single-node cutting bioassay was simpler to perform than the root tip segment and microtuberization bioassays and did not exclude certain genotypes as did the microtuberization bioassay. The single-node cutting bioassay can be recommended as a substitute for more labour-intensive and costly field assessments of salinity effects on yield.

“…Pot and field experiments have shown that, in potato, salinity reduces canopy expansion and advances senescence (Levy, Fogelman & Itzhak, 1988 ;Bruns & Caesar, 1990;Levy, 1992) . Partitioning of assimilate to tubers also appears to be affected by salinity as tuber growth is reduced to a greater extent than canopy growth (Levy, 1992) .…”

“…Sensitivity of the crop to salinity depends on the growth stage, being greatest when stress is imposed from planting as it retards plant emergence (Levy, 1992) . Differential responses of cultivars have been observed either to saline water applied once during the growth of plants in pots (Bruns & Caesar, 1990) or to moderate salinity in the field (Levy, 1992) . Under severe salinity Levy (1992) found little difference in the response of the genotypes examined .…”

Salt-tolerance in potato (Solanum tuberosum L .) was selected on the basis of germination and survival of seed sown in trays of perlite suspended in either 75 or 150 mM NaCl . Salinity reduced the germination of seed . Genetic differences in salt-tolerance were apparent with salt reducing germination more in seed collected from cv . Cara than in that collected from cv. Maris Piper. Progeny from the seedling selection were then grown to maturity to produce tubers .The relative tolerance of the parental cultivars and of unselected and selected progeny to long-term exposure to salinity was examined in a pot experiment in which plants were irrigated with either fresh water or 50 mM NaCl solution from one week after plant emergence . In this experiment, salinity significantly reduced leaf conductance, total dry matter production and partitioning of assimilate to tubers . Salinity reduced dry matter production and assimilate partitioning to tubers to a greater extent in Cara than in M . Piper. Progeny selected for short-term salttolerance did not exhibit greater long-term salt-tolerance than unselected progeny, and both were more sensitive than M . Piper.These results demonstrate genetic variation in salt-tolerance in potato . However, although there was a correlation between the performance of the parent to long-term salinity and survival of progeny in the seedling selection, there was no correlation between short-and long-term salt-tolerance . This suggests that characters underlying short-term tolerance may contribute to long-term tolerance but do not of themselves confer long-term tolerance . Future progress in selecting for improved salt-tolerance depends on understanding the effects of salinity on the physiological processes underlying growth and carbon partitioning .
