چکیده
The study was conducted to investigate the ge-netic basis of kenaf fiber yield and quality In two sets of generations derived from ۱X۵۱ x Gha-na۰۷ and Gregg x Ghana۰۷ crosses. Analysis of generation means using weighted least squares procedure was performed on stalk dry weight, bast percentage, days to flowering, plant height, and basal stalk diameter . Analysis of generation means revealed that bast percentage was mainly controlled by dominance effects whereas stalk dry weight was mainly controlled by additive ef-fects. Estimates of heterosis based on mid-parental values were generally high and ranged from ۱۰ to ۵۵% for stalk dry weight and bast per-centage. Estimates of inbreeding depression, calculated from F۱ and F۲ generation means, were ۵۵% for stalk dry weight in Population ۱ and ۴۳% in Population ۲. Estimates of inbreeding depression for bast percentage were ۵% in Population ۱ and ۱۵% in Population ۲. The results of this study indicated that the portion of phenotypicvariations,which is controlled by addi-tive gene effects, was generally high for stalk dry weight. Thus, selectingthe segregating genera-tions would lead to significant improvement of fiber yield.کلیدواژه ها
