Book Description
An investigation was conducted to determine the extent of diversity and relationships among a worldwide safflower (Carthamus tinctorius L.) germplasm collection and to find out adapted accessions that can be used in an organic safflower breeding program in Germany. A total of 468 accessions were studied under organic farming conditions at Kleinhohenheim experimental station during the seasons of 2004 and 2005. All the accessions were evaluated for 12 phenotypic traits and three rated diseases. Multivariate analyses have been used to measure the diversity in a subset of 200 accessions and 11 geographical regions. Generally, the study showed that there was a large genetic variation within accessions. A coefficient of variation (CV %) for investigated traits and diseases ranged from 2.9 to 91.0% with the highest CV was recorded for yield/m², yield/plant and seeds/plant. The most accessions that originated in Europe revealed relatively better performance compared to non-Europeans. High yielding, early maturing, and disease tolerant accessions were identified. However, the low oil content (8.7-22.8%) is the primary concern in this germplasm collection. The degree of heritability varied between 10% for lodging to 86% for plant height. Genotypic coefficient of correlation (rg) was slightly higher for many traits than the respective phenotypic coefficient. Oil content and seed yield/m² were highly significantly correlated (rg=0.78). The genotypic coefficient of correlation showed that selection for seeds/plant and thousand kernel weight was effective for improvement of seed yield and oil content. The results of the principal component analysis and the clustering pattern of accessions were consistent with the results of analysis of variance. About 78% of the total phenotypic diversity in the germplasm was explained on the basis of four principal components and 88% of the total variation among geographical regions was contributed by the first three principal components. The distribution of the accessions within clusters has no apparent relationship with the geographical origin. However, many of the European accessions have a tendency to stay together.

Book Description
For sustainable environmental management as a whole, the roles of phytoremediation and biofortification as two sides of the same coin must be highlighted. Phytoremediation is a process in which biological organisms are used to eliminate or nullify an environmental pollutant by a metabolic course of action. Biofortification, in contrast, is an agrarian process that enhances the micronutrient content of a food crop through plant breeding, genetic modification, use of enriched fertilizers, or management of agricultural practices. These two strategies, although targeting different objectives, both work on the same principle of the bio-extraction process that involves uptake, accretion, removal, and modification of micro- and macro-nutrient elements from the soil. This volume offers a comprehensive overview of phytoremediation and biofortification of Zn, Fe, Cu, and Cd, etc., and illustrates the emerging and innovative combination of these technologies. With chapters written by experts, the book highlights a wide range of topics and discusses the integration of advanced phytoremediation and biofortification approaches for sustainable ecological and health management. Topics include phytoremediation and biofortification strategies that use nanotechnology; algae, fungi, and other plants; CRISPR/Cas9-mediated genome engineering; and more for decontamination of water and soil and for fortifying plants against climate change, toxic chemicals, and other challenges. Key features: reviews and integrates the currently available information on phytoremediation and biofortification from molecular, biochemical, and physiological levels provides a direction towards implementation of programs and practices to enable the sustainable production of crops, resilient to climatic alterations This volume will be valuable for investigators who are working or have an interest in sustainable environmental management as well as for research students, teachers, scientists, and engineers, whether in academia, industry, or government, and those who have an interest in environmental remediation and micronutrient fields.
