摘要

This study was conducted to evaluate divergent wheat germplasm for their performance under drought and controlconditions. The germplasm consists of wheat land races of Pakistan, advanced D-genome synthetic derivatives and highyielding varieties of Pakistan. This wide array of germplasm was selected to identify sources, which can be opted later bythe wheat breeders while breeding for drought tolerance. The evaluation parameters involved some importantphysiochemical testing and morphological characteristics in the field under drought and control conditions. Based on theseparameters, 13 wheat genotypes were selected on the basis of their best performance regarding morphological andphysiological parameters. These genotypes exhibited higher yield under drought stress conditions and increased percentageof proline, sugar, SOD and protein content under laboratory conditions as compared to the susceptible genotypes.Correlation studies revealed that grains per spike (GPS) and thousand grain weight (TGW) had direct relationship with spikelength (SL), proline and sugar content under both control and drought conditions. Thus, these parameters can be used asselection criteria for the identification of tolerant genotypes.
