Bell pepper belongs to the Solanaceae family and is in high demand as a
vegetable in India, Middle East, USA, Europe and Southeast Asian countries. It has
gained the attention of progressive farmers, consumers and international market
traders because of its rich nutritional profile and ever-increasing export potential
(USD 4.9 billion in 2017). Thirty-eight Capsicum taxa are currently documented in
the USDA Genetic Resources Information Network (GRIN), including the five
under commercial cultivation. In the sixteenth century, bell pepper was introduced
to the Asian continent. Currently, China, India, Pakistan, Bangladesh and Indonesia
shares over 70% of the world’s bell pepper production. The World Vegetable Center
in Taiwan holds the world’s largest Capsicum collection of 8165 accessions, and
covers 11% of global diversity. Besides traditionally-important traits like earliness
and higher yield, bell pepper breeding is now challenged by the emergence of new
pests and diseases. New varieties are needed with desirable fruit color, pungency,
shape and nutritional quality, along with resistance to phytophthora, anthracnose,
bacteria, viruses, powdery mildews, root-knot nematodes, heat, cold, drought and
salinity tolerance; all of these characteristics represent major breeding goals along
with higher yields. Conventional breeding methods like introduction, pure line
selection, pedigree selection, mutational and heterosis breeding, and backcross
breeding are now being assisted by new breeding approaches like rootstock breeding
along with modern genomic tools to break down existing barriers, and to speed
up traditional breeding programs. Development and implementation of hybrid cultivars
are key aspects of bell pepper production, for which the genetic male sterilitysystem is being exploited commercially in both the public and private sectors.
However, in comparison of chili pepper, utilization of the cytoplasmic male sterility
(CMS) system in bell pepper is restricted, owing to high instability of male sterility
expression at low temperature, and poor fertility restoration (Rf) ability. This chapter
describes recent advances in genetic improvement of bell pepper by using various
cultivated and wild species as sources of important traits.
