This book was released on 2013-03-14 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic variability is an important parameter for plant breeders in any con ventional crop improvement programme. Very often the desired variation is un available in the right combination, or simply does not exist at all. However, plant breeders have successfully recombined the desired genes from cultivated crop gerrnplasm and related wild species by sexual hybridization, and have been able to develop new cultivars with desirable agronomie traits, such as high yield, disease, pest, and drought resistance. So far, conventional breeding methods have managed to feed the world's ever-growing population. Continued population growth, no further scope of expanding arable land, soil degradation, environ mental pollution and global warrning are causes of concern to plant biologists and planners. Plant breeders are under continuous pressure to improve and develop new cultivars for sustainable food production. However, it takes several years to develop a new cultivar. Therefore, they have to look for new technologies, which could be combined with conventional methods to create more genetic variability, and reduce the time in developing new cultivars, with early-maturity, and improved yield. The first report on induced mutation of a gene by HJ. Muller in 1927 was a major mi1estone in enhancing variation, and also indicated the potential applica tions of mutagenesis in plant improvement. Radiation sources, such as X-rays, gamma rays and fast neutrons, and chemical mutagens (e. g. , ethyl methane sulphonate) have been widely used to induce mutations.

Book Synopsis User Evaluation of Campgrounds on Two Michigan National Forests by : Robert C. Lucas
Download or read book User Evaluation of Campgrounds on Two Michigan National Forests written by Robert C. Lucas and published by . This book was released on 1970 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Campground use on the Huron and Manistee National Forests in Michigan was studied in relation to resource characteristics, location, facilities provided, and visitor attitudes about the environment. Four factors in combination accounted for 69% of a variation in campground use per unit. Resource quality ratings made earlier as part of a nationwide Forest Service recreation resource inventory did not agree with visitors` ratings and had little relation to use variations. Overall resource quality ratings by visitors were most associated with their judgment of general environmental quality (essentially scenery).
