Special Issue Information

Dear Colleagues,

As the global demand for animal-derived products continues to rise, the pressure on sustainable livestock production systems intensifies. The foundation of this industry lies in a consistent and nutritious supply of forage. Enhancing both the yield and quality of forage crops is therefore paramount to ensuring food security, improving farm profitability, and reducing the environmental footprint of agriculture. This Special Issue, "Genetic Improvement and Cultivation Practices for High-Yield and Quality Forage", is dedicated to exploring the synergistic integration of advanced breeding techniques and precision agronomy to meet these challenges. Genetic Improvements: Application of quantitative genetic, genomics, marker-assisted selection, and genomic prediction for traits such as biomass yield, nutritional quality. Cultivation Practices: Optimized strategies for irrigation, fertilization, harvesting schedules, and stand persistence to maximize both productivity and resource-use efficiency. We seek to compile cutting-edge research that bridges the gap between genotype and phenotype, unlocking the full potential of forage species. We invite the submission of original research articles, reviews, and methodological papers that contribute to the advancement of forage science.

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 250 words) can be sent to the Editorial Office for assessment.

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. Agronomy is an international peer-reviewed open access semimonthly journal published by MDPI.

In this study, 101 F1 hybrid lines were constructed using Medicago sativa L. ‘Xinjiang Daye’ and Medicago falcata L. ‘Hulunbeier’ as parents, and their agronomic and quality traits were systematically evaluated over two consecutive years. The results showed that the hybrid progeny exhibited more pronounced phenotypic variation in the second year. Specifically, the X4H4 combination demonstrated superior biomass accumulation, while the H4X4 combination showed notable advantages in quality indices. In the second year, the correlations among agronomic traits were clearly strengthened, with morphological traits closely associated with biomass; coordinated variation was also observed among quality traits, as crude protein content was negatively correlated with fiber-related indices. Based on principal component and heterosis analysis, the hybrid lines were classified into distinct advantage groups: Group 1 exhibited clear agronomic heterosis, while Groups 2 and 3 displayed distinct advantages in quality traits. Finally, 12 elite individuals were selected based on integrated KASP molecular marker profiling and comprehensive phenotypic evaluation. This study establishes a strategy for marker-assisted phenotypic evaluation in alfalfa breeding, providing a theoretical basis and germplasm resources for the development of high-yield and high-quality cultivars.
