Abstract

Upland rice breeding lines were evaluated in field trials for resistance to the obligate hemi-root parasite Striga hermonthica at two sites in Kenya in 1990 and 1991. The lines differed in their reaction to S. hermonthica ranging from highly resistant to extremely susceptible. IR 49255-B-B-5-2, IR 38547-B-B-B-7-2-2, IR 47255-B-B-5-4 and Ble Chai were confirmed resistant to S. hermonthica. The indication is that the gene for resistance to S. hermonthica is widespread in rice. © 1993.
