油菜籽（甘蓝型油菜）是世界上最重要的油料作物之一。然而，油菜籽最近出现了一种有趣的新用途：作为观赏植物。以这些黄色花朵盛开的田野为基础的旅游业已成为中国新的经济增长机会。从育种的角度来看，目前有两个主要问题限制了油菜籽作为观赏植物的潜力。一是花期较短（平均30天），经济收入受到限制；其次，商业品种的花色目前仅限于亮黄色，这可能很快就会让观光者感到厌烦。本文总结了油菜籽作为观赏植物可能存在的问题，详细介绍了影响花期的因素、如何通过综合优化栽培措施或/和喷洒化学试剂来延长花期，以及培育和培育多种花色油菜籽的方法。
Rapeseed (Brassica napus) is one of the most important oil crops worldwide. However, an intriguing new use for rapeseed has recently developed: as an ornamental. Tourism based on blossoming fields of these yellow flowers has become a new economic growth opportunity in China. From a breeding perspective, two main problems currently limit the potential of rapeseed as an ornamental. First, the flowering period is quite short (30 days on average), which limits economic income; second, the flower color in commercial cultivars is currently limited to bright yellow, which may pall quickly for sightseers. This review summarizes the possible problems of using rapeseed as an ornamental, and details factors affecting the flowering period, how the flowering period can be prolonged by integrating optimal cultivation measures or/and spraying with chemical reagents, and ways of creating and breeding rapeseed with diverse flower colors.
