Eight blast resistance genes --Pia, Pib, Pik-s, Pik-h, Pita, Piz-t, Pi20, and one of three (Pii, Pi3, or Pi5(t)) were identified in 42 IRRI-bred varieties following a differential system using Philippine blast isolates. Among these genes, two genes Pib and one of Pik alleles (Pik-s or Pik-h), were found in almost all IRRI varieties. The number of resistance genes in each variety varied from two to...
In the IRRI-Japan Collaborative Research Project, four kinds of differential varieties, monogenic lines and near isogenic lines (NILs) with three kinds of genetic backgrounds have been developed for the following 24 resistance genes Pia, Pib, Pii, Pik, Pik-h, Pik-m, Pik-p, Piks, Pish, Pita, Pita-2, Pit, Piz, Piz-5 (Pi2), Piz-t, Pi1, Pi3, Pi5(t), Pi7, Pi9 (t), Pi11 (t), Pi12 (t), Pi19 (t), and Pi20...
fourteen qtl for philippine isolates and 12 qtl for japanese isolates were detected in the 14 regions on nine chromosomes (1, 2, 3, 6, 7, 8, 9, 11, and 12) using recombinant inbred lines derived from a cross between indica-type rice milyang 23 and a japonica-type rice akihikari. Among them, several qtl were detected to be common to philippine and japanese isolates. The qtl in two regions on the short...
Partial resistance to blast has not been clearly distinguished from major gene resistance in the tropics. Several major genes for resistance to blast were identified recently in IR varieties at the International Rice Research Institute (IRRI) and the reactions of these genes to the Philippine blast isolates were studied. Consequently, suitable blast isolates could be selected to eliminate the effect...
