Le résumé fourni par la source
Seven near isogenic lines (NILs) for six partial blast-resistance genes— Pi35, pi21, Pi37(t)( Pi37-KRIL17), Pb1, and Pi34 (two: Pi34-Chubu32 and Pi34-Chugoku40, originating from different Japonica Group rice lines, ‘Chubu 32’ and ‘Chugoku 40’, respectively)—and one quantitative trait locus (QTL), PiPHL9, derived from Japonica Group line ‘Hokkai PL9’, were developed in rice ( Oryza sativa L.). These NILs have the genetic background of an Indica Group susceptible line ‘US-2’, which does not harbor complete resistance genes and can clarify the effects of partial resistance genes and the QTL. These NILs and US-2 were used to determine the effects of the partial resistance genes and the QTL based on the results of an inoculation test for leaf blast using international standard differential blast isolates in the young seedling stage and a natural infection test in the mature stage after heading at a blast field. The NILs produced mainly moderate reactions in the inoculation test and rarely exhibited “resistant” and “susceptible” reactions. Each of the partial resistance genes and the QTL had different effects in panicle blast. Two genes, Pi35 and Pb1, were the most effective with respect to resistance, followed by Pi37-KRIL17. Pi34-Chugoku40 was the weakest. The effects of pi21, Pi34-Chubu32, and PiPHL9 varied among cultivation seasons and could be easily affected by environmental conditions. This is the first report clarifying the effects of partial resistance genes without the major complete genes, which will be helpful for advanced genetic and pathological studies and as a source of genes for rice breeding.
