This book was released on 2012-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several morpho physiological traits are traditionally used as screening criteria for drought tolerance such as relative water content (RWC), stomatal index, water use efficiency (WUE) etc. Crop WUE can be improved by optimizing crop transpiration. Several workers have proposed carbon isotope discrimination (CID), ash content and canopy temperature depression (CTD) as selection criteria for transpiration efficiency (TE), which may serve as the surrogate measures for improvement in grain yield.To identify suitable physiological traits useful in wheat breeding under water stress environment is the major thrust area of present investigation. For this, Durum and aestivum genotypes were selected from the breeding material of ARI, Pune (MS, India).Experimental trials on Triticum durum were conducted under three different water regimes viz. residual soil moisture stress (RSMS), post anthesis water stress (PAWS) as limited irrigation (LI) and well watered (WW) conditions.Data were collected for agronomical and physiological characters. Soil water balance model 'BUDGET' (Raes et.al. 2006) has been used for deriving WUE using meteorological, rainfall and irrigation data of (2004-05)and(2006)

Available in PDF, EPUB and Kindle. Book excerpt: The global population is projected to reach almost 10 billion by 2050, and food and feed production will need to increase by 70%. Wheat, maize and sorghum are three key cereals which provide nutrition for the majority of the world's population. Their production is affected by various abiotic stresses which cause significant yield losses. The effects of climate change also increase the frequency and severity of such abiotic stresses. Molecular breeding technologies offer real hope for improving crop yields. Although significant progress has been made over the last few years, there is still a need to bridge the large gap between yields in the most favorable and most stressful conditions.

This book was released on 2007-05-08 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: In biology, the very big global and thevery small molecular issues currently appear to be in the limelight ofpublic interest and research funding policies. They are in danger of drifting apart from each other. They apply very coarse and very fine scaling, respectively, but coherence is lost when the various intermediate levels of different scales are neglected. Regarding SALINITY we are clearly dealing with a global problem, which due to progressing salinization of arable land is of vital interest for society. Explanations and basic understanding as well as solutions and remedies may finally lie at the molecular level. It is a general approach in science to look for understanding of any system under study at the next finer (or "lower") level of scaling. This in itself shows that we need a whole ladder of levels with increasingly finer steps from the global impact to the molecular bases of SALINITY relations. It is in this vein that the 22 chapters of this book aim at providing an integrated view of SALINITY.

Download or read book Morpho physiological Studies For Drought Adaptation In Wheat written by Dipendra Pokharel and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat (Triticum aestivum L.) is the most important cereal crop for global food supply. Most of the wheat crop in developing countries including Nepal is either grown rainfed condition or under limited irrigation condition, thus water stress hits the wheat crop at different growth stages which thus limiting the grain yield. An experiment with 60 different genotypes of wheat was carried out in Nepal for the characterization for drought adaptation.The ANOVA (Analysis of Variance) revealed significant variation between environments and among the wheat germplasms for most of the drought adaptive traits. A wide range of variability was observed for the selected drougt adaptive morpho-physiological traits in moisture stressed and non-stressed environments. WUE was highly significantly correlated with biomass production. Nepalese cultivar Gautam showed a number of favorable drought adaptive traits. A number of landraces and advanced breeding lines showed high level of water use efficiency and other positive traits for drought adaptation.

Book excerpt: Emerging phenotyping methods and increasingly abundant genotyping platforms have become valuable tools for the discovery and introgression of yield-positive and stress-adaptive genes into modern wheat (Triticum aestivum L.). The main goal of this research was to identify genomic regions that contribute to yield potential and drought tolerance in wheat using agronomic and remotely sensed phenotyping approaches. Phenotypic interrelations, genetic variability of yield, yield components, phenology, and spectral reflectance indices (SRIs) were evaluated in a Pacific Northwest (PNW) winter wheat diversity panel (n = 402). The SRIs showed moderate to high phenotypic correlations with grain yield (|r| = 0.27 -- 0.84, p

Download or read book Enhancing Efficiency in Wheat Triticum Aestivum L Breeding for Abiotic and Biotic Stress Resistance Using Novel Physiological and Genetic Approaches written by Megan Johanna Lewien and published by . This book was released on 2017 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: By 2050 global demand for wheat (Triticum aestivum L.) is predicted to grow by 60%. To meet this demand, annual genetic gains must increase by 1.4%, and withstand increasing environmental stresses. The goal of the work herein was to use new phenomic, genomic and molecular tools to identify novel genomic regions associated with eyespot (Oculimacula yallundae and O. acuformis) disease resistance, drought tolerance and yield stability. To identify novel genomic regions associated with eyespot resistance in winter wheat, disease susceptibility was evaluated in two PNW winter wheat panels (n= 469, 399) and genome-wide association mapping was conducted. Of the 92 marker trait associations identified, the seven most significant cumulatively reduced eyespot disease response. As breeding lines were used, the results can be used for rapid introgression of resistance alleles into elite lines. The second objective of this work was to evaluate phenotypic associations of physiological traits and yield under rain-fed conditions to identify traits for use in breeding. 700 lines of the spring wheat nested association mapping panel were evaluated for water use efficiency, plant water status, photosynthetic and photoprotective mechanisms and grain yield over three years. Six traits had a cumulative effect on increasing yield: plant water status, plant height, photosynthetic capacity, vegetative green index, water used efficiency and days from sowing to heading. The physiological traits identified can be used to improve selection efficiency and yield stability under variable rain-fed conditions. The third objective of this work was to identify genomic regions associated with the water-use efficiency, plant water status, leaf health and photosynthesis. 650 lines of the spring wheat NAM panel were evaluated for these traits and grain yield under rain-fed conditions and joint inclusive composite interval mapping and genome-wide association analysis was conducted. The seven most significant grain yield QTL identified, located on chromosomes 1A, 1B, 2B, 4B, 5B, and 7B, were found in multiple environments and were associated with multiple physiological traits. This study helps reveal the genetic architecture of drought tolerance and grain yield and can be used to improve the efficiency of breeding under variable water-limited conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Abiotic stresses are known to adversely impact agricultural productivity on millions of hectares globally, and it is projected that these problems are likely to increase, primarily due to anthropogenic interventions as well as climatic changes. Understanding abiotic stresses—especially salt stress on soil—calls for an interdisciplinary approach because salt-stressed soils need hydro-technical, chemical, and agronomic interventions as well as an understanding of plant response when exposed to these stresses. This volume explores and conveys the latest information on emerging technologies in the management of abiotic salt stress and their field applications. It brings together experts from various fields (academia, technology, and engineering) to provide the latest information and knowledge on this important challenge.
