Breeding for Biotic Stresses Resistance in Vegetable Crops: A Review

Abstract

Abstract

Vegetable pests and diseases have major effect on its production. Although application of fungicides and pesticides has helped control plant diseases and insect/pests, but indiscriminate use of hazardous chemical  causes environment pollution, chemical residues in vegetables above threshold levels and emergence of new races/biotypes. Therefore at this junction, breeding for the development of biotic resistant cultivars is major objective of vegetable breeder’s. Basic research on the genetic bases of pest and disease resistance in vegetable crops and of host-pathogen interactions has greatly improved the efficiency of manipulating disease resistance genes in practical breeding programs and resulted in the development of high-yielding genetically resistant cultivars. For the development of resistant varieties and pre-breed lines, sources of resistance having genetic information is prerequisite and backbone of breeding programme. Attempts will be made to provide a description on resistant sources of different vegetable crops against major diseases and insect pest, inheritance of resistance, genetic manipulations, biotechnological interventions and grafting which will be useful for the vegetable breeders for future breeding programme.
