Plant genetic resources comprising of reservoir of gene and gene complex are basic raw materials for genetic improvement of any crop including vegetables. The book entitled vegetable crops: Genetic Resources and improvement is a compilation of information generated through research work of many scientists in India and abroad from reputed institutes like, IIHR, IARI, GBUAT, TNAU, IIVR, CCSHAU, PAU, MPUAT, CSKKVV, BCKV etc., The book contains introductory on various aspects of collection, characterization, conservation and utilization of germplasm in genetic improvement of different vegetable crops highlighting the importance of genetic resource management and their achievement in India. Application of different biotechnological tools and techniques like, tissue culture, molecular markers and bioinformatics in conservation and utilization of plant genetic resources have been included. The issues related to biosafety regulations and IPR have also been discussed. Genetic improvement of different vegetable crops through utilization of genetic resources have been dealt in s covering all important vegetables including underutilized vegetables, seed spices and edible mushrooms. This book is very helpful to the teachers, scientists, students and personals involved in PGRE management, who wish to update the knowledge on recent technological advances in genetic resource management and improvement of vegetable crops.
