Sweet pepper/Bell pepper (Capsicum annuum L. var. grossum Sendt.) is one of the most popular and widely grown off-season vegetables in many states of India including Himachal Pradesh. All the cultivars and hybrids being grown by the farmers are susceptible to bacterial wilt disease in varying proportion.Therefore present study was undertaken at the Research Farm of Department of Vegetable Science and Floriculture, CSKHPKV, Palampur, Himachal Pradesh, India during summer-rainy season 2007 & 2008 including some bacterial wilt resistant genotypes with the objectives to estimate the combining ability, gene action and heterosis on different yield components, quality, morphological traits and disease resistance in sweet pepper (Capsicum annuum L. Var. grossum Sendt.) following line x tester analysis.Some high yielding, bacterial wilt resistant F1 hybrids were developed which were likely to perform better in the bacterial wilt prone high rainfall areas of Himachal Pradesh.This book covers the genetic, breeding, disease resistance, morphological and yield components of bell pepper breeding programme. It is helpful for researchers, students & vegetable growers to understand the crop breeding

Bell pepper (Capsicum annuum) is a highly consumed vegetable in the U.S. However, it is also highly susceptible to many diseases. Phytophthora capsici is one of the major pathogens of bell pepper production. Introgression of sources of genetic resistance into commercial varieties is an effective approach for disease management. In this study, resistance loci for different isolates in a pepper recombinant inbred line (RIL) population, along with some desirable traits such as fruit size and unfavorable traits associated with the resistant parent, were identified. Quantitative trait loci (QTL) analysis identified the major components of P. capsici resistance, as well as components of resistance that were isolate-specific. QTL for organ (fruit and leaf) size clustered into a few loci in the pepper genome. The linkage map and correlation study revealed relationships among the traits. Genetic and physical genomic maps were used to investigate the candidate genes for all traits. R-gene complexes were proposed to contain the candidate genes for the resistance at the major QTL, whereas three genes on chromosomes 1, 2 and 3 were suggested for organ size. Combining the phenotypic and genotypic data from all traits, a RIL was selected for the resistant parent and crossed to bell-type varieties to develop marketable bell pepper lines containing broad genetic resistance for P. capsici.

Capsicum is the name of the pepper plant genus that includes 27 species, which range from sweet bell peppers to the hottest peppers on the planet. Due to variations in climatic conditions, insects show varying trends in their incidence and extent of damage to the crop.This compilation discusses how, as an effect of these interactions, the production of pepper is affected quantitatively but especially qualitatively.Additionally, the authors study the effect of capsaicin at the cellular signalling level, gene expression, and the use of bioinformatics to understand the mechanism of cell signalling and regulation of gene events taking place between tumorous cell and capsaicin receptors.In closing, all in vitro/in vivo methods reported so far for obtaining doubled haploids in both sweet and hot pepper are compared. The androgenesis, gynogenesis and efficiency are discussed in both hot and sweet pepper species.
