以8个子莲（Nelumbo nucifera Gaertn.）主栽品种‘建选35号’（‘Jianxuan 35’）、‘建选31号’（‘Jianxuan 31’）、‘建选17号’（‘Jianxuan 17’）、‘金芙蓉1号’（‘Jinfurong 1’）、‘鄂子莲1号’（‘Hubei Seed Lotus 1’）、‘蓝天6号’（‘Blue Sky 6’）、‘寸三莲’（‘Cunsanlian’）和‘太空莲36号’（‘Space Lotus 36’）以及1个子莲新品种‘子莲1号’（‘Seed Lotus 1’）为研究材料，比较其观赏性和莲子品质，并运用隶属函数法进行综合评价。结果表明：‘金芙蓉1号’和‘子莲1号’的花为粉红色，重瓣；其他7个子莲品种的花为白色或粉色，单瓣。‘建选35号’的莲子百粒质量最高（470.35 g），‘金芙蓉1号’和‘子莲1号’的莲子百粒质量低于均值。‘建选35号’的莲子为圆形，其他8个品种的莲子为椭圆形。‘寸三莲’和‘金芙蓉1号’的单蓬生莲率较高，分别为70.94%和69.39%。‘建选35号’莲子中可溶性糖含量最高（6.20%），‘鄂子莲1号’莲子中直链淀粉含量最低（21.13%），‘金芙蓉1号’莲子中VC含量最高（98.61 mg·kg^-1），‘建选31号’和‘建选17号’莲子中Ca含量较高（分别为1 668.39和1 637.11 mg·kg^-1），‘建选17号’莲子中P、Fe和Zn含量最高（分别为3 790.21、28.79和19.87 mg·kg^-1）。‘子莲1号’莲子中蛋白质和粗纤维含量最高，分别达11.55%和1.29%，多酚、水分和灰分含量与其他品种无显著差异，直链淀粉、支链淀粉、V_C、Fe和Zn含量高于均值，可溶性糖、Ca和P含量低于均值。隶属函数分析结果显示：‘金芙蓉1号’和‘子莲1号’主要观赏性状和莲子品质相关指标的加权平均隶属函数值分别为0.62和0.58，位于前2位。综合研究结果显示：‘金芙蓉1号’和‘子莲1号’的花部观赏价值远高于其他品种，莲子品质符合食用要求，可作为赏食兼用型子莲品种。

Taking 8 main cultivars of seed lotus （Nelumbo nucifera Gaertn.） namely ‘Jianxuan 35’， ‘Jianxuan 31’， ‘Jianxuan 17’， ‘Jinfurong 1’， ‘Hubei Seed Lotus 1’， ‘Blue Sky 6’， ‘Cunsanlian’， and ‘Space Lotus 36’ and a new seed lotus cultivar ‘Seed Lotus 1’ as research materials， their ornamental value and lotus seed quality were compared， and comprehensive evaluation was carried out by using subordinate function method. The results show that ‘Jinfurong 1’ and ‘Seed Lotus 1’ have pink red flowers with double petals， and the other 7 cultivars of seed lotus have white or pink flowers with single petal. The 100-grain mass of lotus seed of ‘Jianxuan 35’ is the highest （470.35 g）， while that of ‘Jinfurong 1’ and ‘Seed Lotus 1’ is lower than the mean. The lotus seeds of ‘Jianxuan 35’ are round， and those of the other 8 cultivars are oval. Productivity of each lotus seedpod of ‘Cunsanlian’ and ‘Jinfurong 1’ is relatively high， which are 70.94% and 69.39% respectively. Soluble sugar content in lotus seed of ‘Jianxuan 35’ is the highest （6.20%）， amylose content in lotus seed of ‘Hubei Seed Lotus 1’ is the lowest （21.13%）， V_C content in lotus seed of ‘Jinfurong 1’ is the highest （98.61 mg·kg^-1）， Ca contents in lotus seeds of ‘Jianxuan 31’ and ‘Jianxuan 17’ are relatively high （which are 1 668.39 and 1 637.11 mg·kg^-1 respectively）， and P， Fe， and Zn contents in lotus seed of ‘Jianxuan 17’ are the highest （which are 3 790.21， 28.79， and 19.87 mg·kg^-1 respectively）. In lotus seed of ‘Seed Lotus 1’， contents of protein and crude fiber are the highest， which are 11.55% and 1.29% respectively， contents of polyphenol， water， and ash are not significantly different from those of the other cultivars， contents of amylose， amylopectin， VC， Fe， and Zn are higher than the means， and contents of soluble sugar， Ca， and P are lower than the means. The subordinate function analysis result shows that the weighted average subordinate function values of main ornamental characters and quality related indexes of lotus seeds of ‘Jinfurong 1’ and ‘Seed Lotus 1’ are 0.62 and 0.58 respectively， ranking the top two. The comprehensive results shows that the flower ornamental values of ‘Jinfurong 1’ and ‘Seed Lotus 1’ are greater than those of the other cultivars， and their lotus seed qualities meet the edible
