STUDIES ON THE BREEDING OF RICE VARIETIES RESISTANT TO STRIPE DISEASE : II. Genetic Study on Resistance to Stripe Disease in Japanese Upland Rice

Abstract

Data on the seedling reaction of four hybrids between resistant Japanese upland rice and susceptible paddy varieties showed that stripe disease resistance in Japanese upland varieties is controlled by two pairs of complementary dorninant genes, St₁ and St₂. This result suggests that in a backcross breeding program for incorporating stripe disease resistance to paddy rice varieties the selection of resistant seedlings in B₁F₁ generation will effective.
