Characteristic of semi-dwarf mutants in rapeseed (Brassica napus L.)
The objective of present research was to study of morphological and physiological traits (photosynthetic and transpiration rate). Additionally tocopherols content was analysed of mutant lines (4 forms). Plant height of initial line DH-0120 ranges from 120,5 to 130,0 cm with averaged 125,5 cm. Mean plant height of mutant lines ranging from 93,0 to 110,0 cm. The remaining analyzed traits (number of branches, length of silique, number of seeds per silique and 1000 seed weight) were found to have a reduced variation range, particularly response to length of silique tad 1000 seed weight. The photosynthetic rate of mutant lines was increased by 7,7-22,7 μmol-2s-1 in different stage on the beginning of flowering as compared to initial line DH-0120. There was found to any variability oftranspiration rate of studied lines. The tocopherol content were in the range 484- 394 mg/g-1 seeds in mutant lines as compared to the initial line 342,0 mg/g-1 seeds.
