This edited volume presents a comprehensive overview of genome-wide association studies (GWAS) and quantitative trait loci (QTL) mapping across a wide range of vegetable crops and their global significance. It covers the fundamental principles of GWAS and QTL mapping, including the statistical tools and methodologies used, along with insights into genetic resources, STRUCTURE analysis, and the development of bi- and multiparent mapping populations. The book also explores identified QTLs, developed molecular markers, and candidate genes associated with economically important traits in vegetable crops.
Vegetable crops play a crucial role in ensuring food and nutritional security for the growing global population. Grown on approximately 10.86 million hectares worldwide, producing 114.8 million tons annually, these crops not only serve as staple food sources but also as essential cash crops and raw materials for various food industries. This book discusses GWAS and QTL mapping efforts across key vegetable crop groups, including nightshades, cucurbits, brassicas, root and tuber crops, leafy vegetables, and others.
This book is intended for breeders, geneticists, pathologists, statisticians, biotechnologists, seed industry professionals, market managers, and graduate and postgraduate students. It will also benefit stakeholders from both the public and private sectors engaged in vegetable crop improvement. It provides practical guidance for developing breeding strategies and improving economically important traits in vegetable crops.
Dr. Shyam Sundar Dey is Principal Scientist at the Division of Vegetable Science, ICAR-Indian Agricultural Research Institute, New Delhi. He has made notable contributions to the development of doubled haploid lines in crops like cucumber, cabbage & cauliflower, as well as cytoplasmic male sterile lines in cauliflower. He has played a key role in developing 18 hybrids and varieties of various vegetable crops and has registered eight germplasm lines with NBPGR, New Delhi. His research is focused on the development of molecular markers for economically important traits, allele mining, marker-assisted backcross breeding and the creation of genomic resources using indigenous cucumber germplasm and received several awards, including the Fellowship & Associateship of the National Academy of Agricultural Sciences, the INSA Early Career Visiting Scientist award and a postdoctoral fellowship from the University of Western Australia.
