Genetic dissection of plant height-related traits by combined methods in wheat (Triticum aestivum L.).

ABSTRACT:

Background

Plant height-related traits are important for optimal architecture and grain yield in wheat (Triticum aestivum L.). In this study, association analysis based on single nucleotide polymorphisms (SNPs) and structural chromosome variations (SCVs) was performed on eight plant height-related traits in a natural population of 281 accessions. Linkage analysis was applied to two populations: a doubled haploid (DH) population of 180 lines derived from the cross 'Jinchun 7 × Jinmai 919' and a recombinant inbred line (RIL) population of 165 F₁₀ lines from the cross 'DH 118 × Jinmai 919' to verify the genetic effects of stable major loci.

Results

In the natural population, plant height (PH) varied from 69.6 cm to 136.6 cm. PH and internode length decreased graduall
