Genetic Improvement of Solanaceous Crops, Volume 1 : Potato.

Potato is the most significant non-cereal crop. Much attention has been paid to this commercially important crop. The aim of this volume is to capture the recent advances made in improving potatoes using traditional breeding methods as well as genetic engineering technology. The book provides a crit...
