ABSTRACT
The aim of this study is to produce large quantities of yam tubers in the
field from seed tubers derived from vitroplants regenerated from aerial stem cuttings
and farmers’ tuber seeds. Seed tubers from ten yam cultivars, including five from Dioscorea alata (cDa083, cDa053, cDa115, cDa150 and cDa266) and five from Dioscorea cayenensis-rotundata (cDr015, cDr027, cDr150, cDr206 and cDr148)
with distinct agro-morphological characteristics, were used as material. A completely
randomized block design with 3 replications was used. In each block, all cultivars
and seed types were represented. When put into cultivation, the tubers produced
by the vitroplants all germinated and gave 100% healthy plants, compared with 86%
to 100% healthy plants for the seed tubers produced by the farmers. Yields per hectare
ranged from 10 to 25 tonnes for seed tubers produced by in vitro plants, and from 4 to 9 tons for seed tubers produced by farmers.
Seed tubers from vitroplants can therefore be recommended to farmers as a solution
to the problem of seed tuber unavailability.
