Book Description
Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) is a major crop in the southern United States. Papaya ringspot virus-watermelon strain (PRSV-W, formerly Watermelon mosaic virus-1) and Zucchini yellow mosaic virus (ZYMV) affect all agricultural species of the Cucurbitaceae and are of great economic importance because of their destructiveness. Watermelon has not been screened extensively for resistance to PRSV-W. Although there is a resistance source for ZYMV resistance, the identification of additional sources of resistance to ZYMV would be highly desirable since the initial sources of resistance are temperature dependent, or not resistant to some of the more severe strains of the virus. The objectives of this study were 1) to screen the USDA watermelon germplasm collection along with available watermelon cultivars for PRSV-W resistance; 2) to verify the disease rating for the most resistant and most susceptible accessions; 3) to determine the genetic control of PRSV-W resistance; and 4) to screen the U.S.D.A. watermelon germplasm collection along with available watermelon cultivars to identify additional sources of resistance to ZYMV. A total of 1275 plant introduction accessions and 44 watermelon cultivars were screened for PRSV-W resistance. The experiment was a randomized complete block with five replications. Enzyme-linked immunosorbent assay (ELISA) was performed after the last rating to determine whether the virus was in the plant tissue. After the germplasm screening, the most resistant and most susceptible cultigens were retested to verify their reactions. Of the 60 resistant PI accessions in the final retest, eight had resistance with a rating of 3.6 or less for the best, average and maximum ratings: PI 244017, PI 244019, PI 482342, PI 482318, PI 485583, PI 482379, PI 595203, and PI 244018. None of the watermelon cultivars tested exhibited resistance to PRSV-W. Inheritance of PRSV-W resistance was studied in three C. lanatus var. citroides acces.

Book Description
This book provides an overview of the current state of knowledge of the genetics and genomics of the agriculturally important Cucurbitaceae plant family, which includes crops such as watermelon, melon, cucumber, summer and winter squashes, pumpkins, and gourds. Recent years have resulted in tremendous increases in our knowledge of these species due to large scale genomic and transcriptomic studies and production of draft genomes for the four major species, Citrullus lanatus, Cucumis melo, Cucumis sativus, and Cucurbita spp. This text examines genetic resources and structural and functional genomics for each species group and across species groups. In addition, it explores genomic-informed understanding and commonalities in cucurbit biology with respect to vegetative growth, floral development and sex expression, fruit growth and development, and important fruit quality traits.

Book Description
The status of crop biotechnology before 2001 was reviewed in Transgenic Crops I-III, but recent advances in plant cell and molecular biology have prompted the need for new volumes. This volume is devoted to fruit, trees and beverage crops. It presents the current knowledge of plant biotechnology as an important tool for crop improvement and includes up-to-date methodologies.

Book Description
This book is the first comprehensive compilation of deliberations on botany, genetic resources and diversity, classical genetics and traditional breeding, genetic transformation, and detailed enumeration on molecular maps and mapping of economic genes and QTLs, whole genome sequencing and comparative genomics in watermelon, and elucidation on functional genomics. The genomic resources for disease resistance, genomics of fruit and quality traits of watermelon, and molecular and metabolic regulation of nutraceuticals in watermelon are discussed. Mapping of quality traits, and biotic and abiotic resistance is also to be discussed. The genome draft of watermelon and application of genome editing are covered. The book contains approximately 250 pages and over 10 chapters authored by globally reputed experts on the relevant field in this crop. This book is useful to the students, teachers, and scientists in academia and relevant private companies interested in horticulture, genetics, breeding, pathology, entomology, physiology, molecular genetics and genomics, in vitro culture and genetic engineering, and structural and functional genomics. This book is also useful for seed industries.
