Summary:•Branching fractions (BFs) of Cr I for 67 lines were measured by a high-resolution grating spectrometer with a hollow-cathode discharge lamp.•BFs which covered a wavelength ranging from 213-541 nm, by combining the reported radiative lifetime data, corresponding transition probabilities and oscillator strengths were deduced.•The uncertainties for most our BFs values are less than 15%, except for the weaker branches (R<0.05). Branching fractions of 67 Cr I spectral lines, which covered a wavelength ranging from 213-541 nm, were measured by a high-resolution grating spectrometer which recorded the intensity of chromium emission spectrum from a hollow cathode discharge lamp. The corresponding transition probabilities and oscillator strengths were derived by the branching fractions obtained in this work combined with the radiative lifetimes reported in the previous literature.
