We point out that in extended supersymmetric models such as supersymmetric left-right models, it is possible to have leptoquarks that explain the HERA high Q2 anomaly without giving up R-parity conservation. The leptoquarks belong to vectorlike (2, 2, ±4/3, 3 or 3^*) representations of SU(2)L× SU(2)R× U(1)B-L× SU(3)c (denoted G2213). Unlike the R-parity violating scenario, the leptoquarks are accompanied by new superpartners,the leptoquarkino which leads to many intersting signatures in other collider experiments. At Tevatron, pair productions of the leptoquarkino will give rise to dilepton signals very distinct from the top productions. These models can lead to unification of gauge coupling constants at a scale of around 1010 GeV implying that grand unification group is not of the usual SU(5) or SO(10) types but rather an automatically R-parity conserving SU(5)× SU(5) GUT model recently proposed by one of the authors (R. N. M.) which leads to a stable proton.
