Book excerpt: This book describes how the genome sequence contributes to our understanding of allopolyploidisation and the genome evolution, genetic diversity, complex trait regulation and knowledge-based breeding of this important crop. Numerous examples demonstrate how widespread homoeologous genome rearrangements and exchanges have moulded structural genome diversity following a severe polyploidy bottleneck. The allopolyploid crop species Brassica napus has the most highly duplicated plant genome to be assembled to date, with the largest number of annotated genes. Examples are provided for use of the genome sequence to identify and capture diversity for important agronomic traits, including seed quality and disease resistance. The increased potential for detailed gene discovery using high-density genetic mapping, quantitative genetics and transcriptomic analyses is described in the context of genome availability and illustrated with recent examples. Intimate knowledge of the highly-duplicated gene space, on the one hand, and the repeat landscape on the other, particularly in comparison to the two diploid progenitor genomes, provide a fundamental basis for new insights into the regulatory mechanisms that are coupled with selection for polyploid success and crop evolution.

This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic improvement of seed oil content and oil quality had been the main objective of rapeseed (Brassica napus L.) breeders until recently, when interest in improving rapeseed meal (RSM) as a secondary trait increased. Seed oil content is the main source of vegetable oil while RSM is a valuable source of animal feed. RSM is the protein-rich by-product after oil extraction from the seed. The quality of oil in rapeseed, as a source of diet is highly dependent on the relative amount of fatty acids in the seed oil. Total saturated fatty acid content (SFA) in the oil is the sum of palmitic, ste...

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pakistan is lucky to have a over dozen oilseed crops, of which it can afford to grow one or the other in all the seasons of year. Despite their importance in our national economy and trade, the oilseed crops in general, are termed as "Miner/ Marginal crops." The status and approach is indirect result of constant by neglecting the oilseed crops as well as agronomic sector. The present crisis demands much attention for the improvement of oilseed crops. Edible oil is an important constituent of our daily diet. Brassica seed oil has been important source of edible oil in Indo- Pak subcontinent especially Pakistan. Rape seed and mustard are the major contributor's after cotton to the local vegetable oil production and thus improved, can be helpful to some extant in bringing up the gap between production and consumption. Existing Brassica napus varieties are low yielding and late in maturity. This situation urges to breed the varieties with high productivity and early maturity. It is also requirement of the time to develop varieties with shattering, insect pests and disease resistances.

Download or read book Investigating the Link Between Genetic Distance and Seed Yield in Hybrid Brassica Napus L Using Phenotypic and Genotypic Methods written by Alexander Peter Cattini and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brassica napus L. is an economically important oilseed species cultivated across Western Canada. Hybrid B. napus cultivars compose the majority of the market due to their seed yield and agronomic quality. It is important to attempt to predict high-yielding parental combinations in order to conserve resources during experimental hybrid evaluation. Genetic distance between parents has been implicated in producing high-yielding hybrids and is used as one criteria for determining parental combinations.In the current study, the genetic distance between high erucic acid rapeseed (HEAR) genotypes of B. napus was established using both phenotypic and genotypic criteria. Phenotypic criteria took the form of nine agronomic and seed quality traits gathered from 318 distinct B. napus genotypes over the 2013 and 2014 field seasons in Southern Manitoba. Genotypic criteria took the form of either 291,782 SNP markers identified in 231 distinct B. napus genotypes using genotyping-by-sequencing (GBS) or 230 polymorphic sequence-related amplified polymoprhism (SRAP) markers identified in 160 B. napus genotypes. The genetic distance between available pollinators and a single male-sterile female was established using each set of criteria in an attempt to correlate genetic distance with hybrid yield. Regression analysis was conducted with yield data from hybrid genotypes gathered from 37 field sites from 2011-2014. Using the phenotypic-derived genetic distance, a significant correlation between genetic distance and hybrid yield was uncovered explaining either 22 % or 42 % of the variation in hybrid yield depending upon whether hybrids were grown at three or more, or five or more sites in the analysis, respectively. No significant link was found between GBS or SRAP-derived genetic distance and hybrid yield. These results provide evidence that that phenotypic criteria can be used to establish genetic distance with utility in the selection of high-yielding hybrid genotypes.

Book excerpt: Oilseed rape (Brassica napus L.) is the world's third largest source of vegetable oil for human nutrition; also the meal is regularly used as animal feed. Yellow seed is one of the target characters in the breeding program, as it associated to lower dietary fiber content and higher oil and protein content. Mature seeds of B. napus will gradually lose their viability during long term storage; this process is defined as natural aging. Seed viability is influenced by several environmental factors, but partly it is also determined by genetic factors. Seed aging is an acknowledged problem in agr...

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses and addresses the rapidly increasing world population demand for food, which is expected to double by 2050. To meet these demands farmers will need to improve crop productivity, which relies heavily on nitrogen (N) fertilization. Production of N fertilizers, however, consumes huge amounts of energy and the loss of excess N fertilizers to leaching results in the pollution of waterways and oceans. Therefore, increasing plant nitrogen use efficiency (NUE) is essential to help farmers produce more while conserving the environment. This book assembles some of the best work of top researchers from academic and industrial institutions in the area of NUE and provides valuable insight to scholars and researchers by its comprehensive discussion of current and future strategies to improve NUE through genetic manipulation. This book should also be highly valuable to policy makers, environmentalists, farmers, biotechnology executives, and to the hard-core researchers working in the lab.
