Construction of a high-density genetic map and mapping of a spike length locus for rye.

Genetic maps provide the foundation for QTL mapping of important traits of crops. As a valuable food and forage crop, rye (Secale cereale L., RR) is also one of the tertiary gene sources of wheat, especially wild rye, Secale cereale subsp.

Four-Year and Five-Developing-Stage Dynamic QTL Mapping for Tiller Number in the Hybrid Population of Gaertn.

Tiller number (TN) is an important agronomic trait affecting gramineous crop yield. To understand the static and dynamic information of quantitative trait locus (QTLs) controlling TN of Gaertn., both the unconditional and conditional quantitative trait loci (QTL) mapping of TN were conducted using a cross-pollinated (CP) hybrid population with a total of 113 plant lines from the cross between (L.

QTL Mapping of Six Spike and Stem Traits in Hybrid Population of Gaertn. in Multiple Environments.

Most Gaertn. species are excellent sources of forage. The derivative lines of wheat- show elite agronomic traits, and some are valuable for wheat breeding.

Construction of Agropyron Gaertn. genetic linkage maps using a wheat 660K SNP array reveals a homoeologous relationship with the wheat genome.

Agropyron Gaertn. (P genome) is a wild relative of wheat that harbours many genetic variations that could be used to increase the genetic diversity of wheat. To agronomically transfer important genes from the P genome to a wheat chromosome by induced homoeologous pairing and recombination, it is necessary to determine the chromosomal relationships between Agropyron and wheat.
