“…The marked decrease in the growth and development of M1 seedlings obtained in this study by X-ray treatments may be due to the in crease in production of active radicals or due to the increase of radiation induced gross chromosome breakage (Brock 1965, Selim et al 1973). Hence Ml-damage by radiation may be due to the damage of non-genetic (physiological) and genetic targets (Gaul 1964).…”

Hitherto, whole seeds have been mostly used for radiosensitivity studies and comparatively less attention has been paid on the effect of radiation on plant em bryos. When embryos in developing plant are exposed to radiation, they showed a greater amount of radiosensitivity than detached seed. These differences were in regard to germination, seedling lethality, growth and development, R, fertility and morphological anomalies (Mericle and Mericle 1957, Chatterjee et al. 1965, Kawai and Inoshita 1965.It is evident from the published literature that except the authors work (Shome 1966, Bhaduri and Shome 1969), till recently, no work has been done to study the radiosensitivity responses of excised rice embryos. In the present paper an attempt has been made to study the relative radiosensitivity responses of different varieties of rice embryos following embryo culture technique. Materials and methodsPureline seeds of rice (Oryza sativa L.)-'day-neutral' vars. Satika (early) and Ashkhata (late); 'short-day' vars. Badkalamkati-65 (early), Kumargore (late) and Kerangserang (late, Javanese rice) were used in this experiment. Excision of mature embryoDecoated rice grains were superficially sterilized with 95% alcohol for 1min followed by 1min in a 0.1% mercuric chloride solution. Grains were then rinsed throughly in sterile distilled water. Afterwards the sterilized grains were soaked in sterile distilled water for 3 to 4hr (in the case of excised embryos, soaking is ab solutely necessary). After removing the pericarp with a cataract knife, under a dis secting microscope, the whitish embryo becomes distinctly visible. Light pressure with the cataract knife between the boundary zone of embryo and endosperm was enough to free the embryo from the endosperm. Due caution was given during dissection so that the embryos were neither injured nor any endosperm tissue was kept adhering to the dissected embryo.

“…They probably contrast in this respect with radiation-induced major gene mutations (see Gaul, 1964, for references concerning the properties of major gene mutations). Lawrence (1963) Melandrium - Lawrence (1964) Papaver Early Lawrence (1965) Whether the similarity arises because such mutations result from addition or loss of pre-existing genetic material, or its rearrangement, or because genotypes have become adapted to recurrent mutation, remains unclear.…”
