  Linear magnetoresistance is a phenomenon that has been observed in a few
topological compounds that originate from classical and quantum phenomena.
Here, we performed electrical transport measurements, in zero and applied
magnetic fields, on the YSi single crystal along all three principal
crystallographic directions of the orthorhombic crystal structure. For
$I~\parallel~[001]$ and $H~\parallel~[100]$ direction above $\approx 10$~T,
mobility fluctuation driven linear magnetoresistance is observed without any
sign of saturation up to $14$~T magnetic field. Anisotropy in the Fermi surface
is immanent from the angular dependence of the magnetoresistance. Kohler rule
violation is observed in this system and Hall data signifies multiple charge
carriers in YSi.
