Title : Influence of crop management on stability rye yield and some grain quality traits
Abstract:
In this presentation, we will discuss a comprehensive study conducted to evaluate the performance of hybrid and population rye cultivars under two different crop management intensities: moderate intensity management (MIM) and high intensity management (HIM). The aim of the study was to assess grain yield, quality, yield components, and variety stability across two growing seasons (2018-2020) at three distinct locations (Chory?, Laski, and Sobiejuchy) within DANKO Plant Breeding Ltd in Poland. Our findings reveal intriguing insights into the advantages of hybrid cultivars over population cultivars in terms of grain yield. The hybrid cultivars consistently outperformed their population counterparts, exhibiting yield increases ranging from 15.0% to 18.1%, depending on location and crop management intensity. However, it was observed that the protein content of hybrid cultivars experienced a slight decrease of 3.0% for MIM and 6.5% for HIM compared to population cultivars. Throughout the study, we also identified key yield components that significantly influenced the overall yield, regardless of cultivar type. The number of spikes emerged as the most influential factor, followed closely by the weight of a thousand grains and the number of grains per spike, showing their importance in determining yield potential for both hybrid and population cultivars. Additionally, we conducted a stability analysis utilizing the ranking sum of the Shukla variance and the mean of the relative performance (Ysi) of a genotype relative to a standard check. The outcomes revealed a low degree of stability for hybrid cultivars, which led to further investigation into stability patterns. The understanding of stability patterns is crucial for making informed decisions regarding variety selection and resource allocation, especially within the context of sustainable resource management. Overall, our research highlights the potential role of rye cultivation in sustainable resource management practices. By adopting hybrid cultivars, farmers and stakeholders can enhance grain yield and optimize resource utilization. However, careful consideration of protein content and stability is essential for striking a sustainable balance between productivity and nutritional quality. During the presentation, we will delve into the details of our methodology, present key data and results, and discuss the implications of our findings. The insights from this study are expected to contribute significantly to the development of resource-efficient crop management strategies, ultimately supporting the sustainable utilization of agricultural resources. Our research can provide valuable guidance for stakeholders involved in sustainable resource management, contributing to the promotion of sustainable food security and resource-efficient agricultural practices. We look forward to sharing our findings and engaging in productive discussions with the audience regarding the potential benefits and challenges of adopting hybrid rye cultivars for sustainable agriculture.
