EFFECT OF GAMMA- IRRADIATION ON THE SEEDS OF CORCHORUS CAPSULARIS L. AND C. OLJTORIUS L.
M.S. RAHMAN AND M.M. MIA
Abstract
Dry seeds of the variety D-154
of Corchorus capsularis and C.G. of C. olitorius were treated with different dosages of gamma-rays. Observations on germination, seedling height, survival of plants and pollen sterility of first
generation plants indicated that the C. olitorius was more sensitive to gamma- rays than C. capsularis. The frequency of various types of mutations increased with the increase in dosages of radiation in both the species. Around 80 Kr of
gamma-rays for C. olitorius and around 90
Kr for C. capsularis were found to be the optimum workable dose for mutation study in them.
