Single crystals of FeSe1-xTex (0.5 <= x <= 1) have been grown by the Bridgman method. After annealing them at 400 degrees C for 100 h in vacuum, single crystals of x = 0.5-0.9 have exhibited bulk superconductivity. Anisotropic properties of the electrical resistivity and upper critical field, H-c2, have been investigated for the single-crystal FeSe1-xTex with x = 0.6. It has been found that the in-plane resistivity, rho(ab), shows a metallic temperature-dependence, while the out-of-plane resistivity, rho(c), shows a broad maximum around 100 K. The resistivity ratio, rho(c)/rho(ab), is 44 and 70 at 290 K and just above the superconducting transition temperature, T-c, respectively. The anisotropic parameter, gamma H-c2(parallel to)/H-c2(perpendicular to) (superscripts parallel to and perpendicular to indicate field directions parallel and perpendicular to the ab-plane, respectively.), is estimated as 2.7 just below T-c.
