S. Farooq et al., PRODUCTION OF SALT-TOLERANT WHEAT GERMPLASM THROUGH CROSSING CULTIVATED WHEAT WITH AEGILOPS CYLINDRICA .2. FIELD-EVALUATION OF SALT-TOLERANT GERMPLASM, Cereal Research Communications, 23(3), 1995, pp. 275-282
Wheat germplasm produced through wide hybridization and three wheat va
rieties were compared for salt-tolerance potential under field conditi
ons at an electrical conductivity varying between 6-10 dS/m. Comparati
ve performance of the same material with direct sowing and transplanti
ng and possible effects of the cultivation method on the concentration
of sodium (Na+) and potassium (K+) was also studied. There was little
difference in the yield components of the salt-tolerant wheats and li
nes, except for mean grain yield, which was significantly reduced in c
ultivated wheat varieties growing under saline fields compared with no
n-saline fields. Differences due to the method of cultivating plants w
ere also nonsignificant in most cases. Two lines produced significantl
y higher yields under saline conditions compared with wheat variety LU
-26 that was used as a salt-tolerant check. The values for K at the se
edling stage and those for the K/Na ratio at seedling and heading stag
es were significantly higher with direct sowing compared to transplant
ing. The overall performance of the new germplasm under saline fields
was better than that of the salt-tolerant wheat varietiy LU-26.
