Twenty-four qualifying matches took place at the Babu Banarasi Das Indoor Stadium in the Indian city, but were overshadowed by the news that the majority of top seeds in the women's competition had pulled out. 

The top three seeds, He Bingjiao of China, Michelle Li of Canada and Saina Nehwal of India, all withdrew, alongside sixth seed Han Yue and eighth seed Cai Yanyan, both of China. 

Four Indian players progressed into the main draw, with Ashmita Chaliha the first after defeating fellow Indian Aakarshi Kashyap 21-13, 21-18. 

Shruti Mundada then overcame compatriot Ritika Thaker 21-19, 21-13, before Tanvi Lad came back from one set down to win 19-21, 21-18, 21-8 against Prashi Joshi in another all-Indian affair. 

The fourth home favourite to reach the main draw was Rituparna Das, a comfortable 21-10, 21-12 victor against fellow Indian Shikha Gautam.  

In the men's competition, second seed Ng Ka Long of Hong Kong and sixth seed Lu Guangzu of China are no longer competing. 

It was another successful qualifying round for the hosts, with Rahul Yadav Chittaboina easing past compatriot Aryamann Tandon 21-10, 21-16. 

In two other all-Indian contests, Alap Mishra progressed to the main draw with a closely fought 22-20, 22-20 result over Kiran George, and Ansal Yadav beat Chirag Sen 21-18, 21-18. 

Huang Ping-hsien of Chinese Taipei was the final qualifier, recording a 21-10, 21-14 victory over Shreyansh Jaiswal of India. 

The main draw is scheduled to take place tomorrow, when the remaining top seeds enter the competition.
