Download or read book Accelerated Plant Breeding Volume 2 written by Satbir Singh Gosal and published by Springer Nature. This book was released on 2020-09-03 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant improvement has shifted its focus from yield, quality and disease resistance to factors that will enhance commercial export, such as early maturity, shelf life and better processing quality. Conventional plant breeding methods aiming at the improvement of a self-pollinating crop, such as wheat, usually take 10-12 years to develop and release of the new variety. During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop varieties. This edited volume summarizes concepts dealing with germplasm enhancement and development of improved varieties based on innovative methodologies that include doubled haploidy, marker assisted selection, marker assisted background selection, genetic mapping, genomic selection, high-throughput genotyping, high-throughput phenotyping, mutation breeding, reverse breeding, transgenic breeding, shuttle breeding, speed breeding, low cost high-throughput field phenotyping, etc. It is an important reference with special focus on accelerated development of improved crop varieties.

Download or read book The Root Systems of Onion and Allium Fistulosum in the Context of Organic Farming written by P. E. de MELO and published by . This book was released on 2003 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: A massive amount of synthetic fertilizers is needed to grow onions (Allium cepa L.) due to their meager and inefficient root system. While the sustainability of such high-input systems is being questioned, low-input systems, such as organic agriculture, are gaining ground. For organic agriculture, plants have to be good nutrient scavengers. Therefore, productivity and stability of onion production in organic systems can be problematic. Plant breeding can improve the efficiency of onion roots, but breeding relies on available variation and there was no information about that in onions or in Allium. The aim ofthis thesis was to search for variation in root morphology in onion and in its allied species A. fistulosum L., to understand the role this variation could play in organic agriculture and to perform a genetic analysis of root traits. The variation found in root traits in onion was limited, although old onion cultivars had a higher root length density than modern ones. Huge variation was observed between onion and A. fistulosum. A. fistulosum developed substantially more stem-borne and lateral roots and, consequently, a much denser root system. Experiments carried out in an organic farm revealed that onion explored a smaller volume of soil and had a lower root density than A. fistulosum. In addition, onion, contrary to A. fistulosum, showed a reduction in total and fine root density when cultivated in a soil with low nitrogen content. It was also demonstrated that A. fistulosum was very responsive to indigenous and inoculated AMF (50 to 60% increase in both shoot biomass and root length). A Quantitative Trait Locus (QTL) analysis was done on the genetic linkage map of the progeny from the cross A. cepa x (A. roylei x A. fistulosum) to locate some of the genes responsible for the better performance of the A. fistulosum root system. All traits were evaluated in a replicated trial using in vitro cloned plants. QTLs were found fornumber of bulbs (1) and stem-borne roots (2) and, more interesting for breeding, for the number of lateral roots (1) and for the relative root length of fine and thick roots (1). The results showed the feasibility of breeding for onions with improved root systems using the interspecific hybrid between A. roylei and A. fistulosum as a genetic source. Some perspectives on the use of cultivars carrying such roots traits in onion organic production are highlighted.

Available in PDF, EPUB and Kindle. Book excerpt: Microbial Management of Plant Stresses: Current Trends, Application and Challenges explores plant microbiota including isolated microbial communities that have been used to study the functional capacities, ecological structure and dynamics of the plant-microbe interaction with focus on agricultural crops. Presenting multiple examples and evidence of the potential genetic flexibility of microbial systems to counteract the climate induced stresses associated with their host as a part of indigenous system, this book presents strategies and approaches for improvement of microbiome. As climate changes have altered the global carbon cycling and ecological dynamics, the regular and periodic occurrences of severe salinity, drought, and heat stresses across the different regimes of the agro-ecological zones have put additional constraints on agricultural ecosystem to produce efficient foods and other derived products for rapidly growing world population through low cost and sustainable technology. Furthermore chemical amendments, agricultural inputs and other innovative technologies although may have fast results with fruitful effects for enhancing crop productivity but also have other ecological drawbacks and environmental issues and offer limited use opportunities. Microbial formulations and/or microbial consortia deploying two or multiple partners have been frequently used for mitigation of various stresses, however, field success is often variable and improvement Smart, knowledge-driven selection of microorganisms is needed as well as the use of suitable delivery approaches and formulations. Microbial Management of Plant Stresses: Current Trends, Application and Challenges presents the functional potential of plant microbiota to address current challenges in crop production addressing this urgent need to bring microbial innovations into practice. - Demonstrates microbial ecosystems as an indigenous system for improving plant growth, health and stress resilience - Covers all the novel aspects of microbial regulatory mechanism. Key challenges associated with microbial delivery and successful establishment for plant growth promotion and stress avoidance - Explores plant microbiome and the modulation of plant defense and ecological dynamics under stressed environment

Download or read book The Effect of Bulb Size and Plant Density on Yield and Quality of Onion Allium cepa var cepa L Seed at Ziway Central Ethiopia written by Zerihun Zena and published by GRIN Verlag. This book was released on 2013-01-29 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2008 in the subject Agrarian Studies, grade: 3.17, University of Hawassa (Awassa College of Agriculture), course: Horticulture, language: English, abstract: Plant density and bulb size trial was conducted at Ziway in order to identify the optimum agronomic management practices, which contribute to maximized seed production in onion crop both in terms of quantity and quality. The experiment was laid down in split plot design with three replications, keeping plant density as main plot factor and bulb size as sub plot factor. The effects were studied by collecting data on bulb sprouting and plant performance, yield components, seed yield and seed quality parameters. Analyses of variance, mean comparison using least significant difference, correlation analysis were made using SAS computer software. Plant density significantly influenced bulb sprouting, umbel size, seed yield per 100m2and germination percentage. The largest umbel size (4.9cm) was obtained from low plant density; where as the smallest (4.4cm) from high plant density. Maximum seed yield per 100m2(1,163,446 seeds) was collected from high density while low density yielded only 416,240 seeds per 100m2. However the quality of seed in terms of germination was highest for seeds obtained from low density. The influence of bulb size was significant on plant height, number of flower stalks per plant, number seeded florets per umbel, seed per plant, seed per 100m2, seed yield (qt/ha) thousand seed weight. Plants grown from large bulbs produced plants with best height (72.3cm), highest number of flower stalks (8.5), seeded florets per umbel (368.7), seed per plant (1,539), seeds per 100m2(994,434) and seed yield in qt/ha (10.42). Seeds with best thousand seed weight (4.2g) were obtained from medium bulbs and small bulbs performed least in all aspects. Correlation analysis was made to study the relationship among plant growth, yield component, seed yield and quality parameters and their respective influence on yield and yield quality. Positive correlation existed between plant height and umbel size with seeded florets per umbel; flower stalk per plant, plant height, umbel size, seeded florets per umbel and number of seeds per floret with seed yield per plant, which was highly correlated with seed yield (qt/ha). However, further studies ought to be conducted in order to understand clearly, why bulb size and plant density interaction effect was insignificant Key words: Plant density, bulb size, bulb sprouting, plant performance, seed yield and seed quality
