Two varieties of cassava were evaluated in vitro in the screen house and culture room using five different media treatment. Each treatment was replicated 12 times and observed for 5 weeks before subculturing.
There were significant differences in the growth rate of plantlets in different media, which suggests an interaction between treatments and environments. However, F-probability on survival shows that TMS 188/00106 was significantly different from TMS 083/00125 in the culture room than in the screen house. The study confirms that cassava tissue culture can be raised in the screen house but suggests that plantlet should be allowed to survive in the culture room before transferring to the screen
house for further growth.
