It is now clearly understood that within a given environment, crop improvement has to be achieved through superior heredity. “Plant breeding is the purposeful manipulation of qualities in plants to create new varieties with a set of desired characteristics.” Plants with higher qualities are selected by and crossed to obtain plants with desired quality. The process of plant breeding is assumed to be initiated nearly 7000 years ago with the beginning of human civilization. During domestication many morphological, physiological changes have occurred, starting from adaptation to habitats of normal lands and open sun to the shady swamps. This phenomenon occurs in all the wild animals, plants and also in humans, representing that genetic differences in fitness traits exist both within and among the normal populations. Is this an example of necrosis or apoptosis? Some characters have got changed, some have lost and many have developed during domestication. What is the role of saliva in the digestion of food?
