The response of ten different wheat genotypes to three NaCl levels i.e., control, 7.5 and 15 dS m -1 were compared. Increase in salinity level caused significant reduction in plant height, fresh shoot weight, and dry shoot weight. On the basis of relative salt tolerance, genotypes 243/1 and Tob.66 were found to be more tolerant to salinity and KLR-3-4,SARC-I, NIAB-20, NIAB-30, 5039 and 6529-11 were moderately tolerant and the genotypes 4072 and 6142 were least tolerant to salinity. The estimates of broad-sense heritability for these characters ranged 0.09 to 0.68. The data suggested that improvement in NaCl tolerance in bread wheat is possible by exploiting variability through conventional breeding methods.
Correlation between some production traits were computed for 15 wheat varieties/lines. Path coefficient analysis were used to determine the direct and indirect effect of different characters on grain yield. A positive and significant correlation was observed between number of tillers per plant and peduncle length both at genotypic and phenotypic levels. There were highly significant correlation between spike length and grain yield per plant at phenotypic levels and positive significant at genotypic level. Path analysis showed that number of tillers per plant and spike length are the characters which contribute largely to grain yield.
