Chromosomal Abnormalities Arising Under The Action Of Antibiotics In Pisum Sativum

Studies on genetic as well as cytological effects of antibiotics in higher plants are scanty at present. Therefore, in this study we tried to investigate chromosomal and gene mutations arising under the action of antibiotics. Pisum sativum (2n=14) which belongs to sub family papilionaceae of family leguminosae and has comparatively small number of good size chromosome and is a very important legume crop of India, has been chosen as test system for evaluating mutagenic potency of some of the antibiotics. The effect of antibiotics (viz., amoxicillin, streptomycin and tetracycline) treatment on biological damage and genetic changes in M1 and subsequent generation (M2) of its progeny were evaluated in relation to the following parameters; germination, seedling injury, cytological observations, pollen sterility.
