Abstract/ Executive Summary:

Germination and survival decreased with the increase of the irradiation doses. Plant height, number of effective tiller, panicle length, filled grains and grain yield hill^-1 decreased gradually with increased doses of carbon ion up to 60 Gy dose. As expected unfilled grains plant^-1 were increased gradually. At maturity the survived plants could produce grains up to 60 Gy dose while that of 80 Gy dose could not produce any seed.

Keywords: Rice, Carbon ion beam irradiation, M1 generation, Survival and Yield attributes

Location: BINA Farm, Mymensingh

Start Date:

End Date:

Program Area: Variety and Species

Commodity: Rice

Objectives:

To assess the effect of different doses of carbon ion beams on germination, survival, grain yield and yield attributes of Swarna rice.

Methodology:

Seeds were irradiated with carbon ion beams at the doses of 0, 20, 40, 60, 80, 100, 120, 140, 160, 180 and 200 Gy. Two hundred seeds per dose were sown on petri dishes. The germinated seedlings were transferred to pot and finally seedlings were transplanted in the field. Data on germination, survival, plant height, number of effective tiller, panicle length, filled and unfilled grains plant^-1, yield hill^-1 were recorded after harvest from 5 randomly selected competitive plants.
