Gauged B-L is a popular candidate for the origin of the conservation of R parity, i.e.R=(-)^3B+L+2j, in supersymmetry, but it fails to forbid the effective dimension-five terms arising from the superfield combinations QQQL, ucucdcec, and ucdcdcNc, which allow the proton to decay. Changing it to B-x_iL, where x_e+x_μ+x_τ=3 (with x_i≠1) for the three families, would forbid these terms while still serving as a gauge origin of Rparity. We show how this is achieved in two minimal models with realistic neutrino mass matrices, and discuss their phenomenological implications.
