Special Issue Information

Dear Colleagues,

The Special Issue "Improvement of Agronomic Traits and Nutritional Quality of Wheat" focuses on advancing wheat production to meet the dual challenges of global food security and improved quality traits. Enhancing key agronomic and physiological characteristics and quality requires a multidisciplinary approach, combining genetics, agronomy, and biotechnology. This issue explores innovative research on genetic improvement, agronomic practices, and breeding strategies that contribute to grain yield and quality increase.

We seek contributions that delve into the physiological, biochemical, and genetic mechanisms underlying trait improvement, as well as studies employing field trials, genomic tools, or molecular breeding approaches. The overall aim of this Special Issue is to provide new insights for developing high-yielding and quality wheat varieties that are resilient to climate change and adaptable to diverse environmental and production conditions, thus contributing to sustainable food systems worldwide.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Small grain crops showed significant yield variation under different nitrogen fertilization treatments. Understanding factors influencing yield is crucial for optimizing productivity. This study assessed how nitrogen fertilization affects grain number, grain weight, and other yield components in triticale, wheat, six-rowed, and two-rowed barley across multiple locations and seasons. Key traits, including grain number per spike, spike number per unit area, and spike dry weight, were analyzed. Triticale cultivars achieved the highest average grain yield (GY) of 8709 kg ha−1, significantly outperforming wheat (7656 kg ha−1) and six-rowed barley (7676 kg ha−1), particularly under high nitrogen (100 kg N) fertilization, where triticale reached 9184 kg ha−1. Grain number per unit area (GN) was strongly positively correlated with GY across all crops, with the highest GN values observed in triticale (21,937) under 100 kg N fertilization. Fruiting efficiency (FE) and spike dry weight at anthesis (SDWa) showed crop-specific relationships with GN, with the strongest association between GN and SDWa observed in triticale, while FE exhibited the highest values in wheat (112.3) and the lowest in two-rowed barley (82). Triticale’s superior yield was linked to greater grain number and spike dry weight, while wheat’s high fruiting efficiency contributed to its performance. Despite its high spike number and spike dry weight, two-rowed barley had lower grain number per spike, limiting its yield. Nitrogen fertilization improved yield components across all crops, though trade-offs between grain weight and other traits were observed. These findings provide insights for breeders and agronomists in optimizing small grain production. Full article
