Development of a Screening Technique to Assess the Genetic Variability For Heat Stress Tolerance Among Sorghum Germplasms

Determination of the optimum induction and lethal levels of stress are considered the most important prerequisites for the proposed screening technique. This research was conducted at the Faculty of Agriculture at Damascus University in the year ٢٠٠٠. The main objective of this investigation was to screen sorghum lines for heat stress tolerance and determine the effectiveness of the proposed technique in screening for this environmental stress at the seedling stage.
