Abstract


A field experiment was carried out at Kharabo station which belongs to the faculty of Agriculture, Damascus university, during the season 2009 ـ 2010, to evaluate some production and quality indicators of sorghum under water stress tolerance, during the grain filling stage. The experiment was designed according to the randomized complete block design (RCBD), with three replicates. The results of the experiment clearly showed a genetic variability in the response of studied genotypes under water stress conditions, reflected in a significant decline in the studied traits, compared with control. Local genotype KHARABO-234 gave the highest fodder yield under stressful conditions about (58.57 tons.h-1). The genotypes KHARABO-233, KHARABO-230 achieved the highest grain production about (5.08, 4.86 tons.h-1), respectively, and the genotype KHARABO-245 achieved the lowest decline rate in harvest index trait (%1.12) compared with the control . For classified the genotypes KHARABO-233, KHARABO-230, KHARABO-245 as grain genotypes. The genotypes KHARABO-245, KHARABO-234 achieved the highest grain crude protein content (10.15%) under stress conditions without significant differences among them.
