Book Description
There are many wild relatives that have potential as sources for oil, condiments and other products Brassica is one of the major crop genuses that comprise different kinds of economically important food crops like oilseed, vegetables and condiments. It contained six economically important species with great genetic and morphological diversity which are distributed all over the world. The cytogenetics relationships amongst the Brassica crops were established in 1935 by the Korean scientist U. This author showed that the three diploid species, B. nigra (2n= 16, genome BB), B. oleracea (2n= 18, genome CC) and B. rapa (2n= 20, genome AA) gave origin, through interspecific hybridisation, to the three amphidiploid species, B. napus (2n= 38, genome AACC), B. juncea (2n= 36, genome AABB), and B. carinata (2n= 34, genome BBCC) (U, 1935). The evolution and relationship between members of the plant genus Brassica. (Anon., 1935) showed that there were three different ancestral genomes Brassica rapa or Brassica campestris AA - 2n=2x=20 (Turnip, Chinese cabbage), Brassica nigra BB - 2n=2x=16 (Black mustard) and Brassica oleracea CC - 2n=2x=18 (Cabbage, kale, broccoli, cauliflower).

Book Description
Brassica crop species and their allies (Raphanus, Sinapis, Eruca, etc.) are important sources of edible roots, stems, leaves, buds and inflorescences, as well as of edible or industrial oils, condiments and forage. Many well known names of plants or plant products, such as kale, cabbage, brocolli, cauliflower, Brussels sprouts, kohl-rabi, Chinese cabbage, turnip, rape, rutabaga, swede, colza or rapeseed, canola, mustard, rocket, etc. are directly associated to this botanical group.The scientific interest for this botanical group has run parallel to its economical importance, and research achievements in our days would have certainly appeared unimaginable only two decades ago. As the end of the millenium approaches, entirely new fields (transformation, somatic fusion, etc.) have been added to the classical ones. Thus, nobody can doubt the opportuneness of this book, which combines and presents both the basic and applied biological aspects of the Brassica species.

Book Description
Genome sequence studies have become more and more important for plant breeding. Brassicas and Legumes: From Genome Structure to Breeding comprises 16 chapters and presents both an overview and the latest results of this rapidly expanding field. Topics covered include: genome analysis of a flowering plant, Arabidopsis thaliana; the sequence of the Arabidopsis genome as a tool for comparative structural genomics in Brassicaceae; application of molecular markers in Brassica coenospecies; the molecular genetic basis of flowering time variation in Brassica species; quantitative trait loci for clubroot resistance in Brassica oleracea; structural differences of S locus between Brassica oleracea and Brassica rapa; Brassica and legume chromosomes; sequence analysis of the Lotus japonicus genome; introduction of an early flowering accession ‘Miyakojima’ MG-20 to molecular genetics in Lotus japonicus; genetic linkage map of the model legume Lotus japonicus; construction of a high quality genome library of Lotus japonicus; genome analysis of Mesorhizobium loti: a symbiotic partner to Lotus japonicus; molecular linkage map of the model legume Medicago truncatula; genetic mapping of seed and nodule protein markers in diploid alfalfa (Medicago sativa); mapping the chickpea (Cicer arietinum) genome: localization of fungal resistance genes in interspecific crosses.

Book Description
The present status of rapeseed-mustard crops as the third most important source of edible oils is attributable to the success of plant breeders and associate researchers in developing high yielding varieties with improved quality and resistance to biotic and abiotic stresses. However, the need to maximize the production gains and quality at lower economic costis greater than ever before. "Breeding Oilseed Brassicas" was thus conceived to review the past accomplishments in order to identify research gaps and suggest ways and means to meet the challenge of sustainable productivity upgradation. Theoretical and applied aspects ofbreeding, genetics, cytogenetics, crop physiology, and biotechnology are covered. The emphasis is on the application of theoretical knowledge to the solution of problems that confront the Brassica breeders.

Book Description
This reference book provides information on plant cytogenetics for students, instructors, and researchers. Topics covered by international experts include classical cytogenetics of plant genomes; plant chromosome structure; functional, molecular cytology; and genome dynamics. In addition, chapters are included on several methods in plant cytogenetics, informatics, and even laboratory exercises for aspiring or practiced instructors. The book provides a unique combination of historical and modern subject matter, revealing the central role of plant cytogenetics in plant genetics and genomics as currently practiced. This breadth of coverage, together with the inclusion of methods and instruction, is intended to convey a deep and useful appreciation for plant cytogenetics. We hope it will inform and inspire students, researchers, and teachers to continue to employ plant cytogenetics to address fundamental questions about the cytology of plant chromosomes and genomes for years to come. Hank W. Bass is a Professor in the Department of Biological Science at Florida State University. James A. Birchler is a Professor in the Division of Biological Sciences at the University of Missouri.

Book Description
The Indian Society of Genetics and Plant Breeding was established in 1941 in recognition of the growing contribution of improved crop varieties to the country's agriculture. Scientific plant breeding had started inIndia soon after the rediscovery of Mendel's laws of heredity. The Indian Agricultural Research Institute set up in 1905 and a number of Agricultural Colleges in different parts of the country carried out some of the earliest work mostly inthe form of pure-line selections. In subsequent years, hybridization programmes in crops like wheat, rice, oilseeds, grain legumes, sugarcane and cotton yielded a large number of improved cultivars with significantly higher yields. A turning point came in the 1960s with the development of hybrids in several crops including inter-specific hybrids in cotton. And when new germplasm with dwarfing genes became available in wheat and rice from CIMMYT and IRRI, respectively,Indian plant breeders quickly incorporated these genes into the genetic background of the country's widely grown varieties with excellent grain quality and other desirable traits. This was to mark the beginning of modem agriculture in India as more and more varieties were developed, characterized by a high harvest index and response to modem farm inputs like the inorganic fertilizers . India's green revolution which has led to major surpluses offood grains and othercommodities like sugar and cotton has been made possible by the work of one of the largest groups of plant breeders working in a coordinated network.
