Abstract: To address the issues of unstable yield and susceptibility to diseases in winter-spring Chinese flowering cabbage（Brassica parachinensis）cultivation in Fuzhou, this study conducted a systematic evaluation of agronomic traits and yield for 47 new cabbage combinations through field evaluation trials. Using the locally dominant variety Jinpin Lüfeng No. 2（CK）as the control, the experiment adopted a randomized block design, focusing on indicators such as growth period, plant architecture, main bolting characteristics, and disease resistance.The results showed that the combinations CX24449, CX24565, and CX24484 achieved yields of 32,818.5 kg·hm⁻², 32,818.5 kg·hm⁻², and 31,848.0 kg·hm⁻², respectively, representing yield increases of 18.4%–22.2% compared to the control（Jinpin Lüfeng No. 2）, with highly significant yield increases. These combinations also exhibited advantages such as robust main bolting（3.1–3.4 cm in diameter）and strong disease resistance. Additionally, CX24439（29,013.1 kg·hm⁻²）, CX24386（28,672.8 kg·hm⁻²）, and CX24354（30,101.0 kg·hm⁻²）demonstrated outstanding commercial quality and stress tolerance.By integrating yield, commercial quality, and stress tolerance metrics, four superior combinations—CX24449, CX24439, CX24386, and CX24354—were preliminarily selected, providing optimized varieties for winter-spring Chinese flowering cabbage cultivation in Fuzhou.
