In the light scalar meson sector (M < 1.8 GeV) one expects at least one q qbar nonet and a glueball, possibly also multi-quark states. We discuss the present phenomenological evidence for sigma and kappa particles; if real, they could be members of the lightest (quark or multi-quark) nonet together possibly with a_0(980) and f_0(980). Alternatively, the lightest nonet could include f_0(980) but not sigma and kappa. Future decisive experimental studies, concerning tests of symmetry relations, especially in B-decays, are outlined.
