Molecular marker-facilitated pyramiding of different genes for powdery mildewresistance in wheat
，-0001，（）：
Breeding durable resistance ot pathogens and pests is a major task for modern plant breeders and pyramiding different resistance genes into a genotype is one way of achieving this. Three powdery midew resistance gene combinations, Pm2+Pm4a, Pm2+Pm21, Pm4a+Pm21 were successfuly integrated into an clite wheal cultivar Yang158, Doublc homozygotes were selected from a small F2 population with the help of molccular markers, As the parents were near-isogenic lines (NILs) of Yang158. the progenies showed good uniformity in morphologicaland other ono-resistance agromic traits. The present work illustrates the bright prospects for the untilization of molecualr makrers in brceding for host resitance.
