Genetic and Physiological Analyses of the Tolerance Mechanisms to Ferrous Iron Toxicity in Rice (Oryza sativa L.)
Wu, Lin-Bo (2016-04-20)Rice is a widely consumed staple food for more than half of the world population. Iron (Fe) toxicity is a major nutrient disorder affecting rice production. The understanding of the genetic and physiological basis of Fe ... -
Genetic and physiological characterization of traits related to salinity tolerance in an advanced backcross population of wheat
Dadshani, Said Abdul Wali (2018-03-22)In large areas of the world wheat production is highly affected by soil salinity. Increasing the genetic variability of currently used wheat varieties is an efficient approach to overcome production losses and prevent food ... -
Genetic and physiological factors of ozone tolerance in rice (Oryza sativa L.)
Ueda, Yoshiaki (2015-09-02)Intensive human activities have contributed to the increase of tropospheric ozone. Ozone is toxic to plants and causes serious damage to crop production and global food supply. Therefore it is necessary to adapt crops to ... -
Genetic dissection of shoot traits and proline content under control and drought conditions in barley
Muzammil, Shumaila (2018-06-11)Drought is the most severe threat to world crop cultivation and production especially in water shortage areas. Wild barley diversity contains notable variation in phenotype that is essential for its adaptation to abiotic ... -
Genetic Diversity and Population Differentiation Analysis of Ethiopian Barley (Hordeum vulgare L.) Landraces using Morphological Traits and SSR Markers
Abebe, Tiegist Dejene (2010-06-08)Morphological and simple sequence repeats (SSR) were used to analyze a total of 199 landraces collected from 10 administrative regions of Ethiopia and four released cultivars of barley. For the morphological data; experiments ... -
Genetic factors affecting the omega-3 and omega-6 fatty acid variation in egg yolk
Nguyen Thi Kim, Khang (2006)This study aimed to elucidate the genetic divergence of quail lines selected for high and low ω-6:ω-3 PUFAs ratio in the egg yolk by estimation of the genetic parameters, to clone and characterize of the direct candidate ... -
Genetic mapping of quantitative trait loci associated with arsenic tolerance and accumulation in rice (Oryza sativa L.)
Murugaiyan, Varunseelan (2019-09-04)<strong>Genetische Kartierung von quantitativen Trait Loci im Zusammenhang mit Arsentoleranz und Akkumulation im Reis (<i>Oryza sativa</i> L.)</strong><br /> Reis (<em>Oryza sativa.</em> L) ist eines der wichtigsten ... -
Genetic transformation of two high oleic Helianthus annuus L. genotypes using different transformation methods
Mohamed, Sherin Gamal El-Deen Abbas (2005)Stable transformation of two high oleic (HO) H. annuus L. genotypes, cv.capella and SWSR2 inbred line was achieved by different transformation methods. For this, a rapid and efficient regeneration system via direct ... -
Genetic variation of traits related to salt stress response in Wheat (Triticum aestivum L.)
Oyiga, Benedict Chijioke (2017-01-24)Salinity is one of the most severe abiotic stresses perceived by plants, and is continuously increasing due to climatic change and poor irrigation management practices. It is currently affecting ~800 million hectares of ... -
Genetic variations in root architecture traits for water and nitrogen use efficiency in wheat and barley
Siddiqui, Md. Nurealam (2022-11-24)The soil edaphic resources such as water and nitrogen are essential for crop production because they are required by plants for proper growth and tissue development. The global crop production is vulnerable due to rapid ... -
Genome stability assessment in new diverse Brassica allohexaploid crop types (AABBCC) using molecular karyotyping
Quezada Martinez, Daniela Roxana (2024-06-04)Interspecific hybridization and polyploidization processes are known to confer advantages, such as hybrid vigor and increased environmental tolerances. Although cultivated diploid and allotetraploid <em>Brassica </em>species ... -
Genome Wide Association Study and Genomic Selection Models for Nitrogen Use Efficiency in Bread Wheat
Sadeqi, Mohammad Bahman (2024-05-17)Nitrogen (N) as an essential element in the structure of proteins, nucleic acids and chlorophyll plays an important role in grain yield. Nitrogen fertilizer, which is most commonly used in cereal production, is necessary ... -
Genome-wide association study for reproduction traits in maternal pig breeds
Bergfelder-Drüing, Sarah (2015-11-23)The number of piglets born alive (NBA) is one of the most important reproduction traits due to its influence on pig production efficiency. It was shown in several studies that NBA has an antagonistic relationship with later ... -
Genome-wide-association studies (GWAS) on the interaction between the cyst nematode Heterodera schachtii and Arabidopsis thaliana
Anwer, Muhammad Arslan (2018-10-12)Plant-parasitic cyst nematodes are obligate sedentary parasites that infect the roots of a wide range of host plants. In research, the beet cyst nematode Heterodera schachtii infecting Arabidopsis thaliana is often used ... -
Genomic indicators for boar taint and fertility in Landrace and Large White populations
Brinke, Ines (2021-06-14)Castration of male piglets in their first week of life is a commonly used but critically reflected method to avoid boar taint. Fattening of entire males represents a long-term sustainable alternative to castration but ... -
Genomic Prediction and Association Mapping Using Publicly Available Data of German Variety Trials in Spring Barley
Kim, Bongsong (2014-09-12)In recent decades, the implementation of best linear unbiased prediction (BLUP) has been extended beyond its initial purpose for the breeding value (BV) estimation to conduct the association mapping and genomic selection. ... -
