Abstract
Sorghum (Sorghum bicolor L. Moench) stands as the world's fifth major crop, following wheat, rice, maize, and barley. The current study conducted to study the germination and seedling parameters of some sorghum genotypes as well as the morphological grain. The studied genotypes were differed significantly in the studied morphological, germination and seedling parameters. The genotype number 4 (PI574598) characterized by the heights values of morphological grain parameters ie, L, W, A, P and GW, which were 4.3mm, 4.05 mm, 13.69 mm2, 13.92 mm and 34 mg. the highest GP (100%) recorded in the genotypes Giza-15 and Giza-113. Furthermore, they recorded highly MDG (16.67 & 16.87 %) as well as the speed of germination (4.17 & 3.98 seed/day) comparing with the others. Regarding the seedling parameters, Giza-15 was more superior in all parameters as TSL, TDW and SVW, which were 54cm, 0.36 g and 5400 mg, respectively. The most highly heritabilities in broad sense (H) were found in A, FFD, GP, MTG, SL, and RFW. Which were 85, 81, 80.82, 76.96, 88.59 and 83.39, respectively. These results indicating the studied parameters very important in sorghum breeding program.
