[Lambda], [bar [Lambda]], and [ital K][sub [ital S]][sup 0] production is studied in a Monte Carlo dual parton model for hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions with an SU(3) symmetric sea for chain formation (chain ends) but strangeness suppression in the chain fragmentation process. Additionally, ([ital qq])-([ital [bar q]] [ital [bar q]]) production from the sea was introduced into the chain formation process with the same probability as for the [ital q][r arrow][ital qq] branching within the chain decay process. With these assumptions, multiplicity ratios and Feynman-[ital x] distributions for strange particles in [ital h]-[ital h] and multiplicity ratios in heavy ion collisions are reasonably well reproduced.
