“西湖秋韵”和“湘湖秋韵”是以荷花品种“西湖红莲”为父本,“秋艳”和“秋星”为母本,通过授粉杂交方法选育出的具有一定耐寒性且花期较长的荷花品种。本文总结分析了2个荷花品种的选育过程、品种形态特征、生物学特性及其扩繁应用,为耐寒且花期长荷花品种的繁育与应用提供参考。“西湖秋韵”和“湘湖秋韵”2个品种均为大株型,展花期分别能持续到10月中旬和11月中旬。二次栽植后,“湘湖秋韵”品种展花期可延长至12月10日。“西湖秋韵”和“湘湖秋韵”的群体花期分别达154和133 d,具有花色鲜艳、花瓣大及对环境适应性强等优点,可广泛应用于湿地公园建设、河道和湖滨水景绿化改造及小区水体美化等场域。

“Xihu Qiuyun” and “Xianghu Qiuyun” are lotus varieties that have been bred through pollination and crossbreeding methods, with “Xihu Honglian” serving as the male parent and “Qiu Yan” and “Qiu Xing” as the female parents. These varieties are known for their cold tolerance and extended flowering periods. The breeding process, morphological characteristics, biological habits, and propagation applications of these two lotus varieties were summarized and analyzed in this paper, providing a reference for the breeding and application of cold-tolerant and long-flowering lotus varieties. “Xihu Qiuyun” and “Xianghu Qiuyun” were classified as large plant types, and it was found that their blooming periods extend until the middle of October and November, respectively. After being subjected to a second planting, “Xianghu Qiuyun” can have its blooming period extended to December 10th. Flowering periods of 154 and 133 days were observed for “Xihu Qiuyun” and “Xianghu Qiuyun,” respectively. These varieties are characterized by bright flower colors, large petals, and strong adaptability to the environment, and they are considered suitable for widespread use in the construction of wetland parks, river and lakeside landscape greening projects, and the beautification of community water bodies.
