My daughter's jee mains rank is 50,017 (gen), which nits, gfits she can go for?

I am very sorry to say that she won't be able to secure NITs with such low ranks.

As for GFTIs, she may get

• Industrial and Production Engineering at Institute of Technology, Guru Ghasidas Vishwavidyalaya, Bilaspur
• Agricultural Engineering, Computer Science and Engineering , Electronics and Communication Engineering at Assam University, Silchar
• Food Technology at Sant Longowal Institute of Engineering and Technology
• Mechanical Engineering at Shri Mata Vaishno Devi University, Katra, Jammu & Kashmir
• Manufacturing Engineering at National Institute of Foundry & Forge Technology, Hatia, Ranchi
• Electrical Engineering at School of Engineering & Technology, Mizoram University, Aizawl

It is upto you to decide which branch and college you want to select according to your interest.

Hope this helps.

Good Luck!!
