摘要

 以68个重瓣型荷花(Nelumbo nucifera Gaertn.)品种为材料,运用层次分析(AHP)法对其植株整体特征、花部特征、结实和果实特征以及莲蓬特征4个方面共22个指标进行综合评价,建立重瓣型子莲品种的综合评价体系。结果表明:花部特征以及结实和果实特征是影响重瓣型荷花综合评价的关键因子,权重较高。根据综合得分对供试68个重瓣型荷花品种进行分级,其中,Ⅰ级包括‘满堂红’(‘Mantanghong’)、‘星空牡丹’(‘Xingkong Mudan’)、‘粉千叶’(‘Fenqianye’),综合得分较高,分别为4.437、4.152和4.006,可作为重瓣型子莲初筛品种或育种材料,为预期理想品种。对3个初筛重瓣型子莲品种与3个主栽子莲品种‘金芙蓉1号’(‘Jinfurong 1’)、‘建选35号’(‘Jianxuan 35’)和‘太空莲36号’(‘Space Lotus 36’)的鲜莲子品质比较后发现,3个初筛重瓣型子莲品种鲜莲子的横径和质量总体上显著小于3个主栽子莲品种,但在营养品质方面均具有一定的可食用性,其中,‘满堂红’外观品质较好,但食味表现不足,‘星空牡丹’外观品质不足,但食味表现较佳,‘粉千叶’综合表现不足。综上所述,建议将‘满堂红’和‘星空牡丹’作为重瓣型子莲品种进行后续研究。

Abstract

 Taking 68 double-petalled lotus (Nelumbo nucifera Gaertn.) cultivars as materials, 22 indexes of four aspects namely overall plant characteristics, floral characteristics, fruit setting and fruit characteristics, and lotus seedpod characteristics were comprehensively evaluated by using analytic hierarchy process (AHP) method, and the comprehensive evaluation system of double-petalled seed lotus cultivars was established. The results show that floral characteristics and fruit setting and fruit characteristics are the key factors affecting the comprehensive evaluation of double-petalled  lotus with relatively high weight. The 68 double-petalled lotus tested are graded according to the comprehensive scores, in which grade Ⅰ contains ‘Mantanghong’, ‘Xingkong Mudan’, and ‘Fenqianye’. Their comprehensive scores are relatively high, which are 4.437, 4.152, and 4.006 respectively, and they can be used as preliminary screening cultivars or breeding materials of double-petalled seed lotus and are the expected ideal cultivars. After comparing the fresh lotus seeds quality of three primary screening double-petalled seed lotus cultivars with three main cultivated seed lotus cultivars ‘Jinfurong 1’, ‘Jianxuan 35’, and ‘Space Lotus 36’, it is found that the horizontal diameter and mass of fresh lotus seeds of three primary screening double-petalled seed lotus cultivars are significantly smaller than those of three main cultivated seed lotus cultivars in general, but they all have edible quality to some extent regarding nutritional quality. Among them, the fresh lotus seed of ‘Mantanghong’ has the better appearance quality but insufficient taste performance, that of ‘Xingkong Mudan’ has insufficient appearance quality but the better taste performance, and that of ‘Fenqianye’ has insufficient comprehensive performance. Taken together, it is suggested that ‘Mantanghong’ and ‘Xingkong Mudan’ can be used as double-petalled seed lotus cultivars for further study.
