Special Issue Information

Dear Colleagues,

Triticeae crops (wheat, barley, rye, and their wild relatives) provide food for more than 40% of the world’s population and are essential for global food security. Recent advances in the dissection of complex traits of Triticeae crops have been made by integrating genomics, transcriptomics, and proteomics; the accelerated selection for yield, quality, and stress resistance traits by linking more genetic markers to these phenotypes; and gene editing (CRISPR), which enables precise modifications of important agronomic traits. These advances allow the continued progression of molecular breeding in Triticeae crops.

This Special Issue highlights cutting-edge research on molecular breeding and agronomic trait improvement in Triticeae crops. We welcome studies on genetic dissection from QTL/GWAS, gene discovery using omics data, and precise breeding through marker-assisted selection or CRISPR approaches.

Given that nitrogen (N) is a major limiting factor for global crop production, improving low-nitrogen (LN) tolerance in barley is essential for sustaining yields worldwide. Building on our laboratory’s previous quantitative trait locus (QTL) mapping, which identified three LN-specific QTL clusters on chromosomes 2H and 5H, this study investigated the potential of gene pyramiding to improve LN tolerance. We generated two recombinant inbred line populations (C79 and F79) containing these QTLs and evaluated them for thirty-six traits related to yield, agronomy, and N, phosphorus (P), and potassium (K) uptake and utilization. The results confirmed that LN stress significantly reduced most yield, agronomic, and NPK-related traits. Under LN conditions, grain yield and accumulations of N, P, and K in the C79 population increased with the number of QTL clusters harbored by the lines. More compellingly, in the F79 population under LN stress, lines containing all three QTL clusters exhibited superior performance for critical yield components such as grain yield, spike number, grain number, and nutrient efficiency indices. Furthermore, in both populations, lines with the full QTL complement demonstrated higher values for harvest index, grain number, and K harvest index under LN stress than under normal-N conditions. In conclusion, this study is the first to link LN-QTL pyramiding with P and K use efficiency and demonstrates that pyramiding breeding can produce high-yielding barley varieties with enhanced LN tolerance and nutrient absorption capacity.
