The process of plant breeding is assumed to be initiated nearly 7000 years ago with the beginning of human civilization. This results in a plant population with improved and desired traits. 3. Most of the characteristics of wild species have been affected under domestication which involves three processes like mutation, hybridization and gem-tic recombination under the influence of human selection or natural selection. THILAKAR,LS1154SECOND YEAR.M.SC IN LIFE SCIENCES,BHARATHIDASAN UNIVERSITY,TIRUCHIRAPALLI. (Fruit Science) 2. In other words domestication of plants is the change of the ideo-type to adopt them better to manmade environment. In simpler form, the mating between the relatives in a small population is common and this may lower the population’s ability to persist and reproduce which is referred to as inbreeding depression.
