Rapid identification and deployment of major genes for flowering time and awn traits in common wheat.

ABSTRACT: Molecular markers are developed to accelerate deployment of genes for desirable traits segregated in a bi-parental population of recombinant inbred lines (RILs) or doubled haplotype (DH) lines for mapping. However, it would be the most effective if such markers for multiple traits could be identified in an F₂ population. In this study, single nucleotide polymorphisms (SNP) chips were used to identify major genes for heading date and awn in an F₂ population without developing RILs or DH lines. The population was generated from a cross between a locally adapted spring wheat cultivar "Ningmaizi119" and a winter wheat cultivar "Tabasco" with a diverse genetic background. It was found that the dominant Vrn-D1 allele could make Ningmaizi119 flowered a few months earl
