ABSTRACT

 

In this paper experimental investigations on morphological aberrations of the peas with variation in doses of pesticides are studied. The present study reveals that the test pesticides exerted not only a large varieties of cytotoxic and clastogenic effects, but also induce micro as well as macro mutations affecting various growth and yield traits and also brought about gross morphological aberration and other teratogenic effects. Thus, these pesticides are radiomimetic in their cytogenetic and teratogenic effect. Several pesticides are known to have teratogenic effect like that of Captan, Folpet, Difolatan etc. Most of the aberrations comprised stunted growth, bushy habit specially on the top portion of the plant and partial or complete sterility.
