Abstract

The study explored the performance of hybrid and population rye (Secale cereale) cultivars under two different crop management intensities in Poland: moderate‐intensity and high‐intensity management. The focus was grain yield, grain quality, yield components, and variety stability in two growing seasons (2018/2019 and 2019/2020) at three locations. Hybrid cultivars consistently yielded higher grain yields (9.81 t ha−1) than population cultivars (7.90 t ha−1), with increase of 24.9%. However, hybrid cultivars had lower protein content (8.94%) than population cultivars (9.77%). Spike number was the most influential factor on yield, followed by 1000‐grain weight and grains per spike, regardless of cultivar type. Hybrid cultivars displayed a lower degree of stability as assessed using the ranking sum of the Shukla variance and the multi‐trait stability index. Hybrid cultivars were strongly dependent on resistance to fungal diseases, including Septoria (Mycosphaerella graminicola), and increased stability under moderate‐intensity management. Resistance to soil acidification became more important for cultivar stability under high‐intensity management.

作物管理对稳定黑麦产量和一些谷物品质特征的影响

该研究探讨了波兰杂交黑麦（Secale cereale）栽培品种和群体黑麦（Secale cereale）栽培品种在两种不同作物管理强度下的表现：中等强度管理和高强度管理。重点是三个地点两个生长季（2018/2019年和2019/2020年）的谷物产量、谷物品质、产量成分和品种稳定性。杂交栽培品种的谷物产量（9.81 吨/公顷-1）始终高于群体栽培品种（7.90 吨/公顷-1），增幅达 24.9%。然而，杂交品种的蛋白质含量（8.94%）低于普通品种（9.77%）。穗数是对产量影响最大的因素，其次是千粒重和每穗粒数，与栽培品种类型无关。根据舒克拉方差排序和多性状稳定性指数评估，杂交栽培品种的稳定性较低。杂交栽培品种对真菌病害（包括七叶病菌）的抗性有很强的依赖性，在中等强度的管理下，其稳定性有所提高。在高强度管理下，对土壤酸化的抗性对栽培品种的稳定性更为重要。

期刊介绍： After critical review and approval by the editorial board, AJ publishes articles reporting research findings in soil–plant relationships; crop science; soil science; biometry; crop, soil, pasture, and range management; crop, forage, and pasture production and utilization; turfgrass; agroclimatology; agronomic models; integrated pest management; integrated agricultural systems; and various aspects of entomology, weed science, animal science, plant pathology, and agricultural economics as applied to production agriculture. Notes are published about apparatus, observations, and experimental techniques. Observations usually are limited to studies and reports of unrepeatable phenomena or other unique circumstances. Review and interpretation papers are also published, subject to standard review. Contributions to the Forum section deal with current agronomic issues and questions in brief, thought-provoking form. Such papers are reviewed by the editor in consultation with the editorial board.
