We investigate possible production of neutron-rich isotopes of nobelium. We calculate the production cross sections of 261-266No in the multinucleon transfer reactions of the same projectiles (36S,40Ar,48Ca, and 50Ti) and targets (254Es and 248-251Cf) that were used in the previous study for the possible production of neutron-rich isotopes of Md. We find that the production cross sections of neutron-rich No isotopes are about an order of magnitude smaller than those for neutron-rich Md isotopes. By combining the results for the production of neutron-rich No and Md isotopes, we suggest simple expressions which can trace the isotopic trends of the production cross sections of heavy neutron-rich isotopes. The logarithm of the production cross section is proportional to isospin of projectile or target and the Q value.
