This study was conducted to determine the inheritance of rice blast resistance to the blast fungus races IB-49 and IC-17 and selected F 2 -derived lines in the F 3 were tested for their reactions.
Abstract
Rice blast [Pyricularia grisea (Cooke) Sacc.] is an internationally devastating rice (Oryza sativa L.) disease. This study was conducted to determine the inheritance of rice blast resistance to the blast fungus races IB-49 and IC-17. Nine parents were crossed in all possible combinations. Parents, F 1 , F 2 , and selected F 2 -derived lines in the F 3 were tested for their reactions to blast fungus races IB-49 and IC-17 separately in the greenhouse during 1986 and 1987 (...)
