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
