Book excerpt: Excerpt from Variety Studies in Relation to Fusarium Wilt of Peas The centers of origin of a certain group of cultivated plants are generally characterized by many specialized parasites peculiar to a given group of plants. Thus the center, where the diversity of specialized parasites characteristic of a certain group of plants is concentrated, coincides, as might have been expected, with the center of their hosts. The present unequal distribution of pathological work makes it im possible to apply this principle with any degree of accuracy in the case of the pea. Insofar as present information goes the greatest diversity of pea diseases exists in the United States and northern Europe. Fusarium diseases are especially prevalent in the United States, and some have been reported from Europe. On the basis of the present knowledge of the distribution of fusarium diseases of peas and according to Vavilov' s general theory of diversity of pathogens Ethiopia should be a rich field for the investigation of wilt resistance and of variations in the causal organism, but there is no evidence that the organism occurs there. How susceptibility to pea wilt originated can be only a matter of speculation. If it is assumed that the disease did not affect the wild pea types in their native environment then the origin must be sought elsewhere. Several hypotheses might be offered.
