Book Description
Cotton with its valuable natural fiber is an economically important field plant. Resistance against stress conditions and diseases are desired traits in cotton production. Verticillium wilt is one of the major factors resulting in huge cotton yield losses. Control of Verticillium disease has not been successful because of low genetic diversity and a complex disease mechanism. Moreover resistance against Verticillium wilt is a quantitative trait that is regulated by more than one gene and under environmental effects. Due to this complex inheritance, conventional breeding methods have not resulted in efficient resistance. Therefore, it is necessary to develop cotton lines resistant to Verticillium wilt using molecular breeding techniques. In this study we aimed to identify the quantitative trait loci which are responsible for Verticillium wilt resistance. For this purpose, we carried out a Verticillium wilt disease test in a natural population composed of 118 individuals. We inoculated the population with Verticillium dahliae in five replicates. After one month, the symptoms were examined and phenotypic variation was detected and scored. We then used 100 SSR markers for genotyping of the population. Population structure was determined with STRUCTURE 2.2.3. According to results, we determined two clusters. There were 44 and 34 individuals in the first and second clusters, respectively. A total of 40 individuals remained intermixed. Association analysis between phenotypic and allelic data was carried out with TASSEL 2.1. In this way we identified 30 SSR markers associated with Verticillium wilt resistance at a significance level of p

Book Description
In the first study, seedlings of 142 backcross inbred lines (BILs) derived from Upland cotton 'Sure-Grow 747' (G. hirsutum) x 'Pima S-7' (G. barbadense) were evaluated in two replicated tests for plant height, fresh shoot weight and root weight under two treatments [5% polyethylene glycol (PEG) and water-control conditions] using a hydroponic system in the greenhouse. The experiment in each test was a randomized complete block design with three replications. The analysis of variance for the two tests detected significant genotypic variation in PEG-induced stress tolerance within the BIL population and between the parents. Heritabilities were moderate to high and were higher under the control conditions than under the PEG treatment, and the three traits were also significantly and positively correlated. Based on a linkage map with 292 DNA markers, six QTL were detected including two for plant height, and two each for fresh shoot weight and root weight. This study represents the first report in using a permanent mapping population in genetic and linkage analysis of water stress tolerance in cotton.

Book Description
The genus Gossypium provides natural fiber for textile industry worldwide. Genetic improvement in cotton for traits of interest is not up to mark due to scarcity of adequate information about fiber production and quality. Use of DNA markers for overcoming the issues of selection associated with complex traits is the ultimate choice which may lead to initiate breeding by design. Numerous marker-trait associations have been identified for economical traits using linkage analysis in cotton. Currently there is need for developing high-density genetic maps using next-generation sequencing approaches together with genome-wide association studies (GWAS). Efforts have been started in this direction and several QTLs including fiber quality, yield traits, plant architecture, stomatal conductance and verticillium wilt resistance were identified. This chapter narrates genetic diversity, QTL mapping, association mapping and QTLs related to fiber quality traits. The incorporation of various genomic approaches and previously described marker strategies will pave the way for increase in fiber production.

Book Description
The genus Verticillium Nees represents one of the world's major fungal pathogens, affecting crop plants mostly in the cool and warm temperate regions, it also occurs in sub-tropical and tropical areas. There are some six species which cause severe wilting in trees, herbaceous plants and plantation crops. Other species are responsible for non-wilt diseases of banana and mushroom, another species infects insects.The monograph provides a comprehensive reference source on Verticillium, enabling research workers to see what has already been achieved and to identify the many new areas of research in which original contributions could be made to further the understanding and control of this important pathogen and the disease it causes.

Book Description
Preservation of plant germplasm resources is vitally important for mankind to supply food and product security in the globalization and technological advances of the 21st century. Mankind preserved a wealth of available genetic resources of many plant species worldwide. One of the such worldwide plant germplasm resources is available for cotton, a unique natural fiber producing cash crop for mankind. Worldwide cotton germplasm collections exist in Australia, Brazil, China, India, France, Pakistan, Turkey, Russia, United States of America, and Uzbekistan. The objective of World Cotton Germplasm Resources book is to present readers with updated information on existing cotton germplasm resources, highlighting detailed inventory, description, storage conditions, characterization and utilization as well as challenges and perspectives. This book should be a comprehensive encyclopedic reading source for plant research community and students to gather important information on worldwide cotton germplasm resources.
