The Bharatiya Janata Party Tuesday decided to field Bhanu Prakash in the byelection for the Shimoga Lok Sabha seat.
Former chief minister S Bangarappa vacated the seat after he joined the Samajwadi Party.
The BJP will not contest the Tosham and Hissar seats in Haryana.
A meeting of the party's Central Election Committee, presided over by party President L K Advani, cleared nine candidates for byelections to assembly seats in Karnataka, Uttar Pradesh, Goa and Haryana, party Central Election Committee Secretary Shivraj Singh Chauhan told reporters in New Delhi.
He said no other issue was discussed at the meeting that was attended by former prime minister Atal Bihari Vajpayee and Murli Manohar Joshi.
In Karnataka, the party has fielded Premila Nesargi (Chamarajpet). The candidates for Uttar Pradesh are Ram Milan (Haisebazar-SC), Ravindra Jaiswal (Varanasi North), Lakshmi Shankar Ojha (Allahabad West) and Haridwar Dubey (Kheragarh).
Pradeep Nagvenkar (Taligaon), Krishna Kuttikar (Kumbargua) and Ramesh Tavadkar (Ponginim) are the party's candidates for the Goa byelection.
Rambhaj Hooda (Kiloi) is the only candidate fielded by the BJP from Haryana.
Chauhan said the party has decided not to field candidates from Tosham and Hissar where vacancies have been caused by the death of Haryana Agriculture Minister and Bansi Lal's son Surender Singh and industrialist and Power Minister O P Jindal in a plane crash.
Other candidates will be announced later, he said.
