Renormalization effects of large baryon-nonconserving Yukawa couplings {lambda}{sub ijk}{sup {double_prime}}{ovr D{sub i}D{sub j}U{sub k}} lower the right-handed squark masses keeping the left-handed squark masses virtually untouched at the lowest order. At low energy they enhance the mass splitting between left- and right-handed squarks of the same generation as well as intergenerational mass splitting among squarks, potentially detectable in future colliders or in rare decays. The predicted mass of the lightest top squark becomes lower than the experimental bound for larger ranges of parameter space than that of the baryon-conserving case, hence, further constraining the parameter space of a supersymmetric theory when baryon violation is included. {copyright} {ital 1997} {ital The American Physical Society}
