Marker assisted backcrossing breeding has become one of the essential tools in transferring novel genes to adapted varieties and was employed to pyramid three blast resistance genes Pi1, Pi2 and Pi33 to a popular susceptible rice variety ADT43. Gene pyramiding process was facilitated by marker aided selection for both foreground as well as background… (More)
Blast disease is considered as a major limiting factor in the global rice production because of its wide distribution and destructiveness. Near Isogenic Lines (NILs) harboring different blast resistant Pi genes were surveyed for blast resistance along with resistant and susceptible varieties. These genotypes were randomly crossed to transfer disease… (More)
Blast disease caused by the pathogen Pyricularia oryzae is a serious threat to rice production. Six generations viz., P1, P2, F1, F2, B1 and B2 of a cross between blast susceptible high-yielding rice cultivar ADT 43 and resistant near isogenic line (NIL) CT13432-3R, carrying four blast resistance genes Pi1, Pi2, Pi33 and Pi54 in combination were used to… (More)
Due to an unfortunate turn of events, the fourth author's name appeared incorrectly in the original publication and should have read N. Senthil. The correct representation of the authors' names is listed above and should be treated as definitive by the reader.
