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.
