Genetic resource optimization: a core collection of tetraploid wheat from 2,254 NBRP-wheat accessions.

ABSTRACT:

Background

Tetraploid wheat, comprising both Emmer wheat (Triticum turgidum, AABB genome) and Timopheevii wheat (T. timopheevii, AAGG genome), harbors rich genetic diversity that remains underutilized in modern breeding. The National Bioresource Project-Wheat (NBRP-Wheat) conserves over 2,000 wild and landrace accessions of tetraploid wheat. To enhance the accessibility and application of these resources, we aimed to develop a representative core collection and explore its potential in genetic analysis and breeding.

Results

We first assessed the genetic diversity of all tetraploid wheat accessions in the NBRP-Wheat gene bank using Diversity Arrays Technology (DArT), and selected 179 representative accessions to establish a core collection. This core set and T. durum cv. Kron
