Saina, who bagged a bronze medal at World Championship, had skipped the Korea Open due to a slight thigh strain. She took 39 minutes to dispatch Thailand's Pornpawee Chochuwong 21-17 21-9 in the women's singles opening round.
London Olympics bronze medallist Saina will take on reigning Olympic champion Carolina Marin in the next round. Saina has a 4-3 record against the Spaniard, having lost thrice in the last four meetings.
The eighth seeded Indian, who had reached the finals at Singapore Open, will face Hong Kong's Hu Yun next. The World No. 8 Indian has a 2-2 head-to-head count against Yun, having lost twice in 2015.
US Open Grand Prix Gold Champion H S Prannoy and Syed Modi Grand Prix Gold winner Sameer Verma also advanced to the second round with straight-game wins over their respective opponents in men's singles here.
Prannoy will now take on the winner of the match between Chinese Taipei's Hsu Jen Hao and Hong Kong's Ng Ka Long Angus, seeded sixth.
Sameer, on the other hand, will square off against either France's Brice Leverdez or second seed Chinese Shi Yuqi in the next round.
Sameer's elder brother, Sourabh, however, bowed out of the tournament after his fight against seventh seed and two- time Olympic gold medallist Lin Dan of China ended with a 21- 11 15-21 13-21 loss.
Fast-rising doubles player Satwiksairaj Rankireddy also advanced to the mixed doubles second round alongwith experienced Ashwini Ponnappa after defeating Thai pair of Tinn Isriyanet and Pacharapun Chochuwong 21-17 21-13.
However, Satwik and his men's doubles partner Chirag Shetty couldn't get across third seeds Marcus Fernaldi Gideon and Kevin Sanjaya Sukamuljo of Indonesia, going down 25-27 15 -21 in another pulsating contest.
Experienced men's doubles pair of Manu Attri and B Sumeeth Reddy also crashed out after losing 18-21 15-21 to eighth seeds Lee Jhe-Huei and Lee Yang of Chinese Taipei, while third seeded Korean Chang Ye Na and Lee So Hee ended Ashwini and N Sikki Reddy's stay with a 21-17 21-12 win in women's doubles event.
