Abstract

The inheritance of resistance to a Malaysian isolate of rice tungro spherical virus (RTSV) was studied in eight varieties of rice. Analysis of RTSV infection was done by the enzyme-linked immunosorbent assay (ELISA) method. The resistance of rice variety Utri Merah (IRGC 16682) is controlled by a single recessive gene. A single recessive gene present in Basmati 370, Habiganj DW8, Kataribhog, MR 81, Pankhari 203 (IRGC 5999), Utri Rajapan (IRGC 16684) and Y 1036 was found to be allelic to the one in Utri Merah.
