Parwekar (44) was killed last evening near Ladkhed, 25 kms away from here, when his car overturned while returning after attending a function, police said.
Four other occupants of the car sustained injuries.
Chief Minister Prithviraj Chavan, his deputy Ajit Pawar and other ministers besides political leaders across the spectrum, along with hundreds of people, attended the funeral.
"Parwekar was a dynamic personality who was always concerned with development of his constituency. He was sincere and devoted for the fulfilment of his commitment to the social cause," Chavan said.
Condoling the death, Deputy Chief Minister Ajit Pawar said Parwekar was the rising star of Yavatmal.
