Available in PDF, EPUB and Kindle. Book excerpt: Global population is mounting at an alarming stride to surpass 9.3 billion by 2050, whereas simultaneously the agricultural productivity is gravely affected by climate changes resulting in increased biotic and abiotic stresses. The genus Brassica belongs to the mustard family whose members are known as cruciferous vegetables, cabbages or mustard plants. Rapeseed-mustard is world’s third most important source of edible oil after soybean and oil palm. It has worldwide acceptance owing to its rare combination of health promoting factors. It has very low levels of saturated fatty acids which make it the healthiest edible oil that is commonly available. Apart from this, it is rich in antioxidants by virtue of tocopherols and phytosterols presence in the oil. The high omega 3 content reduces the risk of atherosclerosis/heart attack. Conventional breeding methods have met with limited success in Brassica because yield and stress resilience are polygenic traits and are greatly influenced by environment. Therefore, it is imperative to accelerate the efforts to unravel the biochemical, physiological and molecular mechanisms underlying yield, quality and tolerance towards biotic and abiotic stresses in Brassica. To exploit its fullest potential, systematic efforts are needed to unlock the genetic information for new germplasms that tolerate initial and terminal state heat coupled with moisture stress. For instance, wild relatives may be exploited in developing introgressed and resynthesized lines with desirable attributes. Exploitation of heterosis is another important area which can be achieved by introducing transgenics to raise stable CMS lines. Doubled haploid breeding and marker assisted selection should be employed along with conventional breeding. Breeding programmes aim at enhancing resource use efficiency, especially nutrient and water as well as adoption to aberrant environmental changes should also be considered. Biotechnological interventions are essential for altering the biosynthetic pathways for developing high oleic and low linolenic lines. Accordingly, tools such as microspore and ovule culture, embryo rescue, isolation of trait specific genes especially for aphid, Sclerotinia and alternaria blight resistance, etc. along with identification of potential lines based on genetic diversity can assist ongoing breeding programmes. In this book, we highlight the recent molecular, genetic and genomic interventions made to achieve crop improvement in terms of yield increase, quality and stress tolerance in Brassica, with a special emphasis in Rapeseed-mustard.

This book was released on 2013 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different multivariate analyses techniques were used to classify 46 Indian mustard genotypes for 21 quantitative and quality traits and were grouped into seven clusters. The highest inter-cluster distance based on Tocher's method and Euclidean cluster analysis was observed between cluster IV & VII and cluster II & V, whereas intra cluster distance was found in cluster IV. Principal components showed Eigen value more than one were used to plot all the 46 Indian mustard genotypes in 3D plot cumulatively explaining 45.11% variability with highest element value of biological yield per plant, siliqua on main raceme and oil content contributed maximum towards total divergence. A line x tester analysis involving 10 female and 4 male parents, among the parents only four were found to be significantly superior general combiners and six crosses reflected significant desirable sca effects as well as high per se performance for seed yield along with oil quality and component traits. Such type of hybrid might be useful in heterosis breeding and subsequently isolating the desirable segregants in carrying efficient breeding programme for improvement in Indian mustard.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive compilation of deliberations on elucidation and augmentation of the genome of Brassica juncea, one of the leading oilseed crops of the world, popularly called as brown mustard, Indian mustard, Chinese mustard, or Oriental mustard. It includes discussions on genepools; genetic diversity and its characterization; classical genetic and traditional breeding; basics and application of heteroploidy; techniques and applications of introgressive hybridization; in vitro culture for micro-propagation, somatic mutation, somatic embryogenesis, and somatic hybridization; genetic engineering including genetic transformation and gene silencing; and molecular genetic mapping and mapping of genes and comprehensive delineations on genome sequencing and comparative genomics; resequencing for elucidation of origin and diversity; large-scale genome analysis; plastid genome sequence; transcriptomics; metabolomics; proteomics; evolutionary genomics; role of regulatory genes in development and adaptation and their utilization in trait improvement; precise breeding for yield, quality, and resistance to biotic and abiotic stresses; and prospects of genome editing.

This book was released on 2005-07-20 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hitherto, the cultivation of Ethiopian mustard as source of edible oil is limited to Ethiopia only. Although its agricultural potential is beginning to be recognized in some other countries, the crop is rather a subject of experimental investigation than of large-scale production. Its commercial and production acceptance and subsequent spread within Ethiopia and elsewhere seems largely restricted by its low oil and meal quality. As an oilseed crop less important elsewhere, the crop suffers from lack of research investment to generate basic and applied information needed to improve its productivity and quality. Diversity for seed quality traits and random amplified polymorphic DNA (RAPD) markers among germplasm collection from Ethiopia and other countries are not assessed and documented. Genetic information that is essential to improve seed yield and its components is meagre. The phenomenon of heterosis that has achieved great success in the other oilseed Brassicas is not investigated so far. To address some of the above mentioned information gaps, this study comprising a series of laboratory and field experiments was carried out with the following objectives: (1) to asses the level of variability for some seed quality traits in segregating progenies; (2) to asses the genetic diversity in relation to geographic origin within Ethiopia and out side Ethiopia using RAPD markers; (3) to determine the level of heterosis and variation in combining abilities for yield and its components in inbred- and population-derived F1s; (4) to identify pre-harvest plant characteristics and yield components related to yield heterosis ; (5) to estimate genetic parameters of seed yield and its components; (6) to empirically test the predictive value of parental divergence as determined by DNA markers, phenotypic traits and geographic origin to heterosis; and (7) to suggest breeding strategies for utilizing heterosis in Ethiopian mustard.
