Genesis means origin and Evolution narrates change in morphology, genotype and phenotype due to changes caused by man, environment, natural disasters and migration. Horticultural crops-fruits, vegetables, plantation crops, spices, ornamentals, aromatic and medicinal plants-underwent evolutionary processes and steps to reach present forms and types. Breeding for ideotypes, mechanical harvesting, resistance to biotic and abiotic stresses, transgenics and molecular breeding, assisted marker selection and the whole GM technology have accelerated the evolutionary processes. Vol.1 of the present series is enriched with 21 selected horticultural crops contributed by the authorities/experts in their respective fields. It is hoped that this publication would attract world wide audience of students, teachers, evolutionary researchers, botanists, agriculturists, horticulturists, plant scientists and others interested in horticultural crops
