Ezebuiro, N.C., Amanze, N.J. Egesi, C.N,
and
Uwaecheghi .J.
Objective:
1. To detect the salient potentials of our landrace
cultivars of root and
tuber crops for crop enhancement/improvement.
2. To explore the relative yielding capacities and
bulking rates of selected
landrace cultivars of cassava and yam with a
view to selecting early maturing,
salt and drought tolerant ones that could be
used as parents for breeding.
