Abstract: In vitro regenerated rice (Oryza sativa cv. ADT 43) plantlets under ultraviolet-B selection showed altered growth and yield responses. Of the two sets of calli treated with low (10 min d-1) as well as high (30 min d-1) dose of ultraviolet-B (313 nm), shoots regenerated from low dose ultraviolet-B treatment evinced increased growth and yield. Panicle length and the number of grains were highest in ultraviolet-B (10 min) selected plantlets as compared to the control. Re-irradiation of treated plantlets showed increase in panicle length and grain numbers. Weight of the grains was also high in ultraviolet-B adapted plants. Key words: Calli, irradiation, grains, panicle, re-irradiation.
