Abstract

1. Application of X-rays resulted in 6.39 per cent of sterile rice, and none in the controls.2. Different responses occur with different exposures as also in the diffetent stages of muturity of the germ track.3. The induced sterile rice contained 7.18 per cent of mosaics for different degrees of sterility or for fertile and sterile ears.4. The frequency graph of the percentages of fertile spikelets on sterile rice is a bimodal curve, indicating the characteristic distribution of the genic or chromosomal abnormalities.
