Available in PDF, EPUB and Kindle. Book excerpt: Mutation breeding has been introduced into modern plant breeding in the early 1940's. In spite of pessimistic predictions, the application of experimental mutagenesis has led to encouraging results demonstrating that mutation breeding is a well-functioning method in many crops. So far, more than 500 varieties, developed by means of induced mutations, have been officially released; others have been approved for registration. Many mutants with characters of agronomic interest cannot be utilized directly because of their unsatisfying yielding capacities, or of other negative traits which are partly due to the pleiotropic action of the mutant genes. Sometimes their negative selection value can be overcome by transferring them into the genomes of other varieties. According to experience available, the efficiency of mutant genes can conSiderably vary depending on the genotypic background in which they become effective. The interactions between mutant genes and genotypic back ground cannot be predicted. Therefore, mutants with valuable traits should be crossed with many varieties and strains in order to discern positive and negative interactions. In this way, genotypes can be selected in which the mutant gene is able to express its action without showing negative by-effects. This procedure has been used for about 10 years by combining the methods of mutation and crossbreeding. Mutation breeding is predominantly used in annual diploid and allo polyploid self-fertilizing crops, while it causes much more difficulties in cross-pollinating species.

Download or read book Plant Modification For More Efficient Water Use written by John Stone and published by Elsevier. This book was released on 2012-12-02 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Modification for More Efficient Water Use is a compilation of the proceedings of the Symposium on Plant Modification for More Efficient Water Use. These proceedings aim to make significant progress in identifying the physiological and morphological characteristics of plants by providing considerable control of evapotranspiration and by exploring their possible manipulation. This book is divided into four parts focusing on genetic engineering, physiological and environmental factors, and modeling. The first part includes articles about breeding, genetic engineering, use of variety isogenes, genetic modification, and phenotype and drought tolerance in relation to efficient use of water. The second part presents articles about plant responses to water deficit, water-use efficiency, water stress, and drought resistance. It also provides articles on plant-water balance, carbon dioxide requirement, soil physical and chemical barriers, and soil temperature and air temperature. The third part describes models of plant growth for yield prediction; light models for estimating the shortwave radiation regime of plant canopies; and soil-plant-atmosphere model. In addition, this part includes a parametric analysis of the anatomy and physiology of the stomata. The last part offers a challenge on plant modification for more efficient water use.
