Genetic Diversity In Agriculture
Beginning of paper
Genetic variation is the raw material for the plant breeder, who must
often select from primitive and wild plants, including wild species, in search
of new genes. The appearance of new diseases, new pests, or new virulent forms
of disease causing organisms makes it imperative that the plant be pr ....

.... and variations is necessary in
assembling genetic diversity in plant crops. In certain geographical areas
there has existed a rich source of variability in crop plants but the
encroachment of civilization has reduced the natural variability inherent in
primitive plant forms and related species of crop plants. Agricultural process,
as a result of new breeding programs, has reduced rather than increased crop
variability as improved cultivars, or varieties, are planted in wider and wider
