INDUCTION OF USEFUL MUTATIONS IN BASMATI RICE

G. BARI AND M.A. AWAN
Abstract

---

Dry cells of rice variety Basmati-370 were exposed to 15, 20, 25 and 30 kR of gamma rays, and 1.0, 1.5 and 2.5 kR of fast neutrons. In M1 generation the pollen and spikelet fertility decreased with corresponding increase in radiation exposure. In M2 the frequency of chlorophyll mutations increased as the radiation dose increased up to 2.0 kR of fast neutrons and 25 kR of gamma rays whereafter
