Accessions; Atale temidire, Uromi, Red ginger, and Kaddiodowere assessed for growth and yield performances in a high rainforest agro-ecology of Rivers State Nigeria. Single plantlets of the 4 accessions were raisedin 20kg of soil contained in perforated polythene bags. The research was conducted with 3 replications in a completely randomized design. The following data were analysed using the F-test in ANOVA; plant height, number of tillers andleaves, lamina lengthand width, length of parent/mother rhizome and yield per plant.Mean values obtained were comparedwith LSD (P=0.05). Uromi 36.9cm, and Red ginger 33.8cm, were significantly taller than Atale temidire 20.3cm, and Kaddiodo 17.8cm and had significantly higher lamina width; Uromi 12.8cm, Red ginger 11.7cm, than Atale temidire 7.5cm and Kaddiodo 6.3cm. Red ginger 15, Uromi 13, Atale temidire 13, had significantly more leaves than Kaddiodo 8. Length of mother rhizomes of Atale temidire 12.2cm, Uromi 12cm and Red ginger 11.2cm were significantly different from Kaddiodo 6.2cm. Yields of Atale temidire 925g, Red ginger 873g and Uromi 848g were significantly higher than Kaddiodo 504g. The 3 genotypes are recommended for further evaluation and cultivation over larger areas of the region. Copyright@ International Science Community Association
