Hybrid Embryo Rescue: A Non-Conventional Breeding Strategy in Horticultural Crops

Production of interspecific and intergeneric hybrids is useful for transfer of desirable genes from wild species into cultivated species. In many instances, progeny from wide crosses is difficult to produce owing to several barriers. Post-zygotic barriers such as endosperm abortion and, at later sta...
