Book Description
Peppers and eggplants are two leading vegetable crops produced and consumed worldwide. To facilitate the breeding for agronomical traits such as disease resistance and quality, diverse molecular genetic studies have been carried out. Recent achievements on pepper genome sequencing and trait-linked marker development have enabled the cloning of genes involved in useful traits. This book explores the agronomical and evolutionary characteristics of peppers and eggplants and the results of molecular genetic studies. Topics include molecular linkage maps and candidate gene approaches in capsicum and the structure of the pepper genome.

Book Description
Analysis of genetic diversity is useful in selecting diverse parental combinations, reliable classification of accessions, for exact identification of variety, for conservation and utilization of plant genetic resources. In the present work genetic diversity in 23 chilli genotypes was analyzed by RAPD markers generated by 13 random primers out of which 9 were polymorphic. The amplification profile of these 9 primers consisted of 63 fragments of size ranging from 391 bp to 2754 bp of which 35 were monomorphic and 28 were polymorphic with 44.4 % polymorphism. The number of bands generated by each primer varied from 5 (OPB-10) to 9 (OPB-01 and OPB-15) with an average of 7 fragments per primer. The percentage of polymorphic bands with different primers ranged from 14.29 to 66.67 %. The similarity coefficients detected by RAPD ranged from 0.42 to 0.97 which revealed existence of limited genetic variation among chili genotypes. The consensus tree constructed showed three major clusters. First cluster comprise of 13 genotypes, second cluster of 7 genotypes and third cluster of 3 genotypes. The RAPD technology proved useful in describing genetic diversity among chilli genotypes

Book Description
Over the following four chapters, a multidimensional approach is utilized to contribute to the understanding of the domestication of C. annuum. A number of research tools (ecological, genetic, and sociological) are utilized to investigate the myriad of ways in which the genetic diversity of C. annuum is shaped during domestication and continues to be shaped. The organization of genetic diversity in the domesticated gene pool in a crop is the result of the effect and interaction of multiple factors that belong to the biological, environmental and human realms. An understanding of genetic diversity for conservation and utilization therefore requires a dissection and unraveling of these multiple factors and their interactions. In the following chapters, we describe our efforts to contribute to our collective understanding of the domestication of C. annuum. We describe in detail the efforts made to assemble an unprecedented collection of wild Capsicum from Mexico. We report on the genotyping of this collection, how genetic diversity is partitioned amongst the wild populations, and the genetic clustering of these populations and their relationship to domesticated C. annuum. Of exceptional interest is one of the clusters contained all the domesticated C. annuum and wild populations from Tamaulipas, Nuevo León and the Yucatán. We followed this with a recounting of a new and unique use of an ecological tool, a species distribution model, which was used with a number of different variants of wild Capsicum presence data. Finally, we chronicled the seed saving and selection process amongst chile pepper farmers in central Mexico, finding that those planting varieties of dried chile continue to plant landraces, while those who plant varieties of fresh chiles use hybrid seed, purchased from multinational seed corporations. On the basis of our collection and the genetic relationships uncovered, our results strongly support the hypothesis that C. annuum was domesticated in northeastern Mexico, somewhere near the borders of Veracruz, Tamaulipas and Nuevo León.

Book Description
This book contains complete information on Capsicum genetic resources, diversity, evolution, history and advances in capsicum improvement from classical breeding to whole genome sequencing, genomics, databases and its impact on next generation pepper breeding. Capsicum is one of the most important Solanaceae crops grown worldwide as vegetables and spices. Due to its high economic value and to meet the demands of enormous population growth amid biotic and abiotic stresses, there has been an ongoing breeding program utilizing available genetic resources with desired traits to increase the sustainable productivity of this crop for several decades. However, the precision breeding of this crop for desired traits only started with the advent of molecular markers. The recent advances in high-throughput genome sequencing technologies helped in the quick decoding of transcriptome, epigenome, nuclear and organeller genomes, thereby enhancing our understanding of the structure and function of the Capsicum genome, and helping in genomics assisted breeding. These advanced technologies coupled with conventional mapping have greatly contributed towards dissection and manipulation of economically important traits more precisely and made less time consuming.
