The large volumes of research works that have been done, and the information accumulated over the years necessitated the need for immediate publication of a good updated text book on breeding ornamental flower crops to keep the readers abreast with the current literature and development in the subject.It presents the breeding work on 37 ornamental and flower crops and describes the skills necessary for taking up the cultivar improvement program on these flowers. The opening chapters are meant to provide basic information to the subject, history and development of ornamental plant breeding and major work going on at global level.The major part of the book then considers breeding of all economically important ornamental and flower crops of tropical, sub-tropical and temperate regions. Each chapter is supported by a comprehensive list of bibliography to facilitate readers, locating finer details of the past and recent work of the crop(s).To help readers, some topics in a chapter are broken down into short sub-sections in order to convey the gist of a subject area. The book will serve as an excellent source of reference for flower scientists and teachers too. Additionally, it should be useful to others (enlightened growers, nurserymen, flower traders, agricultural extension officers and policy makers) who wish to become familiar with the topic in relation to their professional interest. However, a basic knowledge of botany and genetics is preferable to fully appreciate the text.
