Comparing Growth Characters of Detoxified Seedling in Different Generations of Chewing-cane‘Badila'

Seedlings of the first (Treatment A) , second (Treatment B) and third (Treatment C) generations derived from detoxified chewing cane Badila'were used as materials to evaluate their production traits.The seedlings without detoxification used as control (CK) .The results showed that the agronomic traits and quality of seedlings were better in detoxification than in control (CK) .The yield and surge content of second (Treatment B) and third (Treatment C) generations were significantly higher than that of CK for 27% and 0.5%, respectively.The productive characteristics indicated that the detoxified seedling in second and third generations were good for using in commercial sugarcane production, while the detoxified seedling in first (Treatment A) generation was suited for propagation.Detoxified seedlings were sensitive to mosaic virus and infective rate to the virus was increasing concomitant with seedling generation development.Therefore, it is important in protective control for detoxified seedlings against the spread of mosaic virus.
