Abstract: | Different cultivars of cow pea and garden pea seeds were surveyed for susceptibility or resistance towards the toxigenic and
aflatoxin-producing mould (Aspergillus flavus IMI 102135). The results show that aflatoxin production varied among the different cultivars of both cow pea and garden pea.
Morphological and histological characters of the different cultivars tested did not show any relation between colour, shape
and size of seeds and the amount of aflatoxin produced.
The chemical analysis of the different constituents obtained from both seed coats and seed kernels with susceptible, partially
resistant and resistant cow pea and garden pea cultivars revealed that the resistant cultivars of cow pea (namely: Balady
cultivar) and garden pea (namely: Melting Sugar cultivar) contained lower levels of sodium and higher levels of phosphate
and potassium. |
