We consider the spin and orbital Kondo effect in a parallel arrangement oftwo strongly electrostatically coupled quantum dots. Increasing the exchange ofelectrons between the dots through the attached leads induces the transitionbetween the SU(4) spin- and orbital Kondo effect and SU(2) spin Kondo effect.Being the same for the SU(4) and SU(2) symmetry points, the Kondo temperaturedrops slightly in the intermediate regime. Experimentally, two kinds of Kondoeffects can be discriminated by the sensitivity to the suppression of the spinKondo effect by Zeeman field. The dependence of Kondo temperature on Zeemanfield and the strength of electronic exchange mediated by the leads is analyzedin detail.Comment: 5 pages, 3 figures. Consideration extended to include finite orbital  magnetic fields. References added, typos correcte
