Identification, development, and exploitation of insect-resistant/tolerant cultivars is an economically viable, ecologically safe and farmer-friendly tactic. Developing insect-resistant cultivars was successful in vegetable crops like tomato, brinjal, okra, cauliflower, and potatoes because of their wider gene pool as well as short duration. In contrast, developing insect-resistant/tolerant cultivars of fruit crops, tea, and coffee has been less explored. This warrants for concerted research attempts. Conventional hybridization, mutation breeding, grafting, and other resistance breeding methods are being employed to develop insect-resilient cultivars. Molecular approaches to harness such desirable traits are also attempted and the field success of such cultivars needs to be validated. Transgenic cultivars of these horticultural crops are yet to be popularized due to environmental paradox and consumers’ perplexity. |
