It is mainly focused on forecasting their performance and suitable circumstances. This is a useful technique for plant breeding for selecting crop plants according to the requirements. Crop breeding is mainly concerned with the creation, selection and fixation of superior phenotypes to develop better lines or cultivars. This book aims to shed light on the genetics, genomics and breeding of crop plants. It elucidates new techniques and their applications in a multidisciplinary manner. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in this area at various levels.
