摘要: F-2 plants from Yang94-138 x 92R149 were analyzed using species-specific probe pHv62 for Haynaldia villosa (L.) Schur and RFLP probe Psr113 located on the short arm of homoeologous group six for wheat ( Triticum aestivum L.). The results showed that the transmission rate of 6VS in the F-2 was 69.5%, which was close to the expected value of 75%. 147 F-2 plants from the above F-1 plant were tested for their resistance in seedling stage to 6 pathogenic strains of powdery mildew. It was observed that Pm21 genes on 6VS inherited dominantly and expressed well when transferred to wheat-"Yangmai 158" genotype.
