Identification of Leaf Rust Resistance Genes in Egyptian Wheat Cultivars by Multipathotypes and Molecular Markers

Other claims from this paper (19)

Observation Twenty leaf rust resistance genes were postulated in nine Egyptian wheat cultivars from infection types against 72 pathotypes.
Observation Giza168 may contain five resistance genes: Lr2c, 10, 18, 24 and 41.
Observation Misr1 may contain five resistance genes: Lr3, 10, 19, 22b and 24.
Observation Sakha94 probably contains Lr9, 19, 29 and 37.
Observation Gemmeiza9 probably contains Lr18, 21, 24 and 41.
Observation Gemmeiza10 probably contains Lr3, 9, 19 and 29.
Observation Sids12 probably contains Lr9, 19, 26 and 29.
Observation Misr2 probably contains Lr3, 10, 19 and 26.
Observation Gemmeiza11 probably carries only Lr24 and Lr41, the fewest genes among the cultivars.
Observation Lr41 was postulated in four cultivars.
Observation Lr3, Lr9, Lr10, Lr26 and Lr29 were each postulated in three cultivars.
Observation Lr2c, Lr21, Lr22b and Lr37 were each postulated in only one cultivar.
Observation The abstract reports PCR-marker identification of five genes, Lr9, Lr10, Lr19, Lr24 and Lr26.
Observation Lr9 was marker-identified in Sids12.
Observation Lr10 was marker-identified in Misr1.
Observation Lr19 was present in Misr1 and Misr2.
Observation Lr24 and Lr26 were absent in all screened Egyptian cultivars.
Method / resource The authors report marker agreement with gene postulation and usefulness of molecular markers combined with multipathotype tests at pre-breeding.
Recommendation Markers for Lr9, Lr10 and Lr19 may aid marker-assisted breeding, and the combined approach may inform wheat–pathogen interactions and leaf rust management.
