Flower Breeding And Genetics

Floriculture is one of the fastest-growing sectors of commercial agriculture. This book provides a unique and valuable resource on the many issues and challenges facing flower breeders, as well as the industry at-large. Featuring contributions from 32 international authorities, it offers tools and directions for future crop domestication and enhancement as well as offers essential information for breeding a wide range of floriculture crops.

The intent for a book of this kind was deeply felt by us in the recent years, in view of the marked advances in breeding and seed production of flower crops especially in the last two decades and the lack of up-to-date compilation on the various aspects of genetics of major flower crops of the world. 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.

Plants have been successfully selectively bred for thousands of years, culminating in incredible yields, quality, resistance and so on that we see in our modern day crops and ornamental plants. In recent years the techniques used have been rapidly advanced and refined to include molecular, cell and genetic techniques. An Introduction to Plant Breeding provides comprehensive coverage of the whole area of plant breeding. Covering modes of reproduction in plants, breeding objectives and schemes, genetics, predictions, selection, alternative techniques and practical considerations. Each chapter is carefully laid out in a student friendly way and includes questions for the reader. The book is essential reading for all those studying, teaching and researching plant breeding.

Brighter zinnias, fragrant carnations, snappier green beans Plant Breeding for the Home Gardener makes it easier than ever to breed and grow your own varieties of vegetables and flowers. This comprehensive and accessible guide explains how to decide what to breed, provides simple explanations on how to cross plants, and features a basic primer on genetics and advanced techniques. Case studies provide breeding examples for favorite plants like daffodils, hollyhocks, roses, sweet corn, and tomatoes.

The development of new plant varieties is a long and tedious process involving the generation of large seedling populations for the selection of the best individuals. While the ability of breeders to generate large populations is almost unlimited, the selection of these seedlings is the main factor limiting the generation of new cultivars. Molecular studies for the development of marker-assisted selection (MAS) strategies are particularly useful when the evaluation of the character is expensive, time-consuming, or with long juvenile periods. The papers published in the Special Issue “Plant Genetics and Molecular Breeding” report highly novel results and testable new models for the integrative analysis of genetic (phenotyping and transmission of agronomic characters), physiology (flowering, ripening, organ development), genomic (DNA regions responsible for the different agronomic characters), transcriptomic (gene expression analysis of the characters), proteomic (proteins and enzymes involved in the expression of the characters), metabolomic (secondary metabolites), and epigenetic (DNA methylation and histone modifications) approaches for the development of new MAS strategies. These molecular approaches together with an increasingly accurate phenotyping will facilitate the breeding of new climate-resilient varieties resistant to abiotic and biotic stress, with suitable productivity and quality, to extend the adaptation and viability of the current varieties.

Breeding New Plants and Flowers brings the skills of hybridizing a unique plant within the scope of every gardener. Over 180 color illustrations and 50 line drawings support the text and explain the steps to this most rewarding and magical aspect of gardening. Topics covered include an introduction to the principles of breeding; descriptions of the breeding of some 30 plants, ranging from fuchsias to roses and tomatoes to strawberries; instruction on pollination, growing the seed, seedling care, taking leaf cuttings, potting on and planting out; and advice on how beginners can crossbreed successfully and how the more experienced hybridist can experiment with sophisticated crosses.

Flowers are the precious gift which beautify the nature through its different colours and enhance human health. Ornamental plants provide environmental security for immediate living surroundings, thus intensive research in floriculture particularly on the crops were initiated earlier. This book will vividly highlights genetical and breeding application in flower crops covering wide range of aspects. Breeding techniques are largely focused around expediting the production of superior and stable lines in the case of self pollinating crops. Wide hybridization, tissue culture and mutagenesis are employed by breeders to generate new alleles. Broaden available genetic resources; molecular markers are used to assist breeders through marker assisted selection and to identify quantitative trait loci for traits of interest. The book makes the knowhow of breeding in its easiest way to the readers. It has been designed to cover all the aspects of breeding, the basic objectives, different breeding methods, methodology for improvement of specific crops, stress resistance, quality improvement, mutagenesis, molecular breeding and genetic engineering.
