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.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought is a limiting factor for wheat (Triticum aestivum L.) production in the low precipitation regions of the Pacific Northwest (PNW). To improve wheat performance in drought, this study focused on three main objectives. Our first objective was to determine water use efficiency (WUE) in the PNW wheat lines through carbon isotope discrimination (CID) technique. Genotypic variation of CID was found in soft spring and hard winter wheat lines. Low CID or high WUE was found important for increasing yield of soft spring wheat lines in drought and semi-drought environments but not in other wheat types. The second objective of this study was to determine important physiological traits associated with yield. Fifteen spring wheat, 140 Alpowa/Express (AE) recombinant inbred lines (RILs) and 165 Hollis/Drysdale (HD) RILs, were evaluated in replicated field trials in two moisture environments, rainfed and irrigated, in different years. The wheat materials were screened for physiological (CT, CID, FLS: Flag leaf senescence), agronomic and phenological traits. The low canopy temperature (CT) was consistently associated with high yield in all wheat lines. The study found that CT was the main driver of wheat adaptation in drought in studied environmental conditions. Our third objective was to identify genomic regions associated with the studied traits through quantitative trait loci (QTL) mapping. In the AE population, yield and test weight QTL were identified on chromosome 1B in the irrigated environments but none of the QTL for physiological traits was found in this chromosomal region. The major QTL associated with yield and CT (at milking), which explained 15 and 22% of the phenotypic variation, were found on chromosome 3B in terminal drought environment. In the HD population, two QTL associated with yield were identified on chromosomes 2A and 4A in averaged rainfed environments in which yield QTL on chromosome 4A explained 35% of the phenotypic variation. These QTL for yield were associated with later FLS. Through the genetic dissection of yield into component traits, this study may help to incorporate quantitative traits into wheat drought breeding programs through marker-assisted selection.
Book Synopsis Physiological Attributes of Drought-adaptation and Associated Molecular Markers in the Seri/Babax Hexaploid Wheat (Triticum Aestivum, L.) Population by : Juan Jośe Olivares-Villegas
Download or read book Physiological Attributes of Drought-adaptation and Associated Molecular Markers in the Seri/Babax Hexaploid Wheat (Triticum Aestivum, L.) Population written by Juan Jośe Olivares-Villegas and published by . This book was released on 2007 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agronomic and physiological traits associated with drought adaptation were assessed within the Seri/Babax recombinant inbred line population, derived from parents similar in height and maturity but divergent in their sensitivity to drought. Field trials under different water regimes were conducted over three years in Mexico and under rainfed conditions in Australia. Results demonstrate an efficient development of molecular markers associated to physiological traits under specific soil water conditions in Mexico and Australia, and suggest further genomic and transcriptomic studies be conducted for unravelling the complex relationship between drought adaptation and performance under drought.

Aestivum L.) and Its Wild Congeners to Drought Condition In Vivo and In Vitro written by Nina Terletskaya and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the complex analysis of different wheat species tolerance to drought stress in¬†vivo at different levels of organization as well as in¬†vitro on callus cultures, which was conducted, are presented. The objects of research are as follows: species of wheat,ÄîT. monococum L. (Au), T. dicoccum Shuebl. (AuB), T. polonicum L. (AuB), T. aethiopicum Jakubz. (AuB), T. macha Dek.et.Men. (AuBD), T. compactum Host. (AuBD), and T. aestivum L. (AuBD). The methods of this research are physiological, biotechnological, and cytological. The focus was on nonspecific reactions of cereals to osmotic stress, and species-specific changes according to growth and anatomical and photosynthetic parameters which depend on studied species ploidy were shown. It was shown that results of testing of plant tissues in¬†vivo and in¬†vitro are comparable. It demonstrated the criterions for selection of drought-tolerant forms. Optimal selection criteria were identified, and more drought-resistant wheat species were identified.
Book Synopsis Studies on Physiological Traits in Wheat Under Water Stress Condition by : Sukhada Shinde
Download or read book Studies on Physiological Traits in Wheat Under Water Stress Condition written by Sukhada Shinde and published by LAP Lambert Academic Publishing. 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)
