Abstract

 

Some statistical procedures like correlation, stepwise regression, factor analysis and cluster analysis were used to study the relationship between wheat grain yield and some physiological parameters under drought conditions. Results reveal that the ratio fv/fm of chlorophyll fluorescence is the most effective parameter to select for tolerant genotype with more grain yield in water limited condition. Based on the results, it is reasonable to assume that high chlorophyll capacity of wheat plants under drought conditions could be identified by selecting breeding materials with high chlorophyll capacity and less proline content.

 

Key words: Wheat grain, drought, chlorophyll, tolerant genotype.
