对88个粳型和10个通州型水稻品种的抗病基因及其抗稻瘟病效应进行了分析。利用分子标记技术对韩国水稻品种的13个抗稻瘟病基因进行了筛选。28例(28.6%)含有来源于日本的日本血吸虫基因。来自BL1和BL7的Pib基因被整合到39个韩国日本品种中,而来自IRRI-bredCDV品种的Pib基因在所有同型品种中都被检测到。在17个日本品种中发现了Piigene基因。韩国水稻品种中的PIIGNE来源于韩国品种农白和日本品种HITOMEBORE、INABAWASE和Todorokiwase。Pi5基因与Piion 9号染色体成簇,仅在Antongil型Taebaeg型中被鉴定。发现34个品种含有抗病基因PitaorPia-2的等位基因。PITA-2基因来自藤条280和Sadominori,PITA-2基因来自日本的Shimokita。17个日本品种和1个通心型品种含有PIZ基因,在日本品种中,PIZ基因起源于福光和公元前54年-68年。3个桐型品种所含的Piz-t基因来源于水稻品种。韩国、日本和桐属品种中存在的Pi9(T)基因座位不是从野生稻Pi9(T)基因中遗传来的。在24个供试品种中检测到Pik-复等位基因Pik、Pik-m和Pik-p。在所测试的任何韩国水稻品种中都没有发现从籼稻K59遗传的PIT基因。对2个QTL和5个主效抗病基因及2个基因PizesPitas的单倍型分析表明,Piz1和Pitas对韩国稻瘟病苗圃和分离物表现出稳定的抗性效应。
A total of 98 varieties consisting of 88japonicaand 10Tongil-typeof rice were analyzed to resistant genes and their effects to blast. The 13 major blast resistance (R) genes againstMagnaporthe oryzaewere screened in a number of Korean rice varieties using molecular markers. Twenty-eight (28.6%) were found to contain thePiagene originating from Japanesejaponicarice genotypes. ThePibgene from BL1 and BL7 was incorporated into 39 Koreanjaponicavarieties, whereas this same gene from the IRRI-bredindicavarieties was detected in allTongil-typevariety. ThePiigene was found in 17 of thejaponicavarieties. ThePiigene in Korean rice varieties originates from the Koreanjaponicavariety Nongbaeg, and Japanesejaponicavarieties Hitomebore, Inabawase, and Todorokiwase. ThePi5gene, which clusters withPiion chromosome 9, was identified only in anTongil-type, Taebaeg. Thirty-four varieties were found to contain alleles of the resistance genePitaorPia-2. ThePitagene injaponicavarieties was inherited from the Japanesejaponicagenotype Shimokita, and thePita-2gene was from Fuji280 and Sadominori. Seventeenjaponicaand oneTongil-typevarieties contained thePizgene, which in thejaponicavarieties originates from Fukuhikari and 54BC-68. ThePiz-tgene contained in threeTongil-typevarieties was derived from IRRI-bredindicarice varieties. ThePi9(t)gene locus that is present in KoreanjaponicaandTongil-typevarieties was not inherited from the originalPi9gene from wild riceOryza minuta. ThePik-multiple allele genesPik,Pik-m, andPik-pwere identified in 24 of the varieties tested. ThePitgene inherited from theindicarice K59 was not found in any of the Korean rice varieties tested. In haplotype analysis for the loci related to two QTLs as well as five major resistant genes and, twogenesPizandPitashowed stable resistant effects to blast nurseries and isolates in~Korea.
