| Abstract | ||
| Full diallel crosses conducted to develop tobacco hybrids using three cultivars; Corjo (A), Sumer48 (B) and Croillo (C), during 2004, Hybrid trail carried out in the green house using Randomized Complete Block Design with 3 parents, 6 hybrids and 2 control, Habana and CV. 48.Significant differences were found among parents and hybrids in studied characters except necotin and ash percentages. The crosses (AxB) and (BxC) superior in pH (6.71 & 6.37), while the crosses (AxB) superior in sugar percentage, the reciprocal hybrid (BXA) had highest burne speed (0.101 mm/sec.). Genetic parameters analysis revealed, that average degree of dominance were higher than one, broad sence heratibiliy, also highest, narrow sence heratibility were lowest. It was recommended hybridization method in the improvement of pH, burne speed and sugar percentage of tobacco, using best hybrid (AXB). | ||
