The tournament, being held in India in February, will be a fifth World Cup for Edwards, whose team are reigning champions following their triumph in Australia in 2009.
Eight members of that victorious squad are included this time, while there are six players experiencing their first World 50-over competition.
Tammy Beaumont, Heather Knight, Danielle Hazell and Danielle Wyatt, along with the uncapped Amy Jones from Warwickshire, were all part of the ICC World Twenty20 squad to reach the final in Sri Lanka in October but have never played in the 50-over Women's World Cup.
Bowler Georgia Elwiss will be experiencing the world stage for the first time in her career and is the only addition to the recent World Twenty20 squad.
Edwards said: "The whole team is really excited about defending our world title in Mumbai in February. "I'm so proud to be captaining such a talented team in what is the pinnacle event in our sport."
Drawn in Group A, England will face India, West Indies and Sri Lanka, with the top three from that stage moving through to the Super Six round along with the top three teams from Group B (Australia, New Zealand, Pakistan and South Africa).
England women's squad: Charlotte Edwards (Kent) (captain), Tammy Beaumont (Kent), Arran Brindle (Sussex), Katherine Brunt (Yorkshire), Holly Colvin (Sussex), Georgia Elwiss (Sussex), Lydia Greenway (Kent), Jenny Gunn (Nottinghamshire), Danielle Hazell (Yorkshire), Amy Jones (Warwickshire), Heather Knight (Berkshire), Laura Marsh (Kent), Anya Shrubsole (Somerset), Sarah Taylor (Sussex), Danielle Wyatt (Staffordshire)
