摘　要：

以本地主栽草莓(Fragaria × ananassa)品种‘丰香’和‘法兰地’为对照, 应用逼近理想解的排序方法(DTOPSIS法)对11个草莓品种的产量、果实品质等11个性状指标进行综合评价, 筛选出了适合在广西地区推广种植的优良草莓品种。其中赋予产量性状指标中的平均单株产量的权重值最大, 为0.3500, 赋予果实品质性状指标中的可溶性糖含量权重值次之, 为0.1500。11个供试品种中, 9个品种的综合性状表现优于对照, 其中, 具有自主知识产权的草莓新品种‘艳丽’的综合性状最优, 理想解的相对接近度(C_i)及平均单株产量均为第1位; 国外引进品种‘本妮西亚’综合性状较优, C_i值及平均单株产量均位于第2位; 而‘斯坦勒’、‘丰香’、‘甜查理’、‘法兰地’4个品种综合性状表现较差, 不适合继续引进种植。草莓新品种‘艳丽’及引入的‘本妮西亚’具有株型适中、产量高、果实硬度高、果实可溶性糖含量高、抗病性强等优点, 可作为良种在广西地区进一步示范推广。

Abstract:

In order to select proper cultivars to promote the extension in Guangxi region, dynamic technique for order preference by similarity to ideal solution (DTOPSIS) method was applied to evaluate eleven trait factors of the thirteen varieties of strawberries (Fragaria × ananassa). The result show that compared to main cultivars ‘Toyonoka’ and ‘Flange’ in Guangxi, the excellent strawberry varieties ‘Yanli’ and ‘Bennisia’ were screened out. The weight value of the yield per plant was the largest one (0.3500), and the weight value of the content of soluble sugar was the second one (0.1500). Nine varieties were superior to the control varieties ‘Toyonoka’ and ‘Flange’. New cultivar ‘Yanli’ with proprietary intellectual property rights and introduced variety ‘Bennisia’ that were superior. Comprehensive traits could be applied to plant in the Guangxi region. ‘Stella’, ‘Toyonoka’, ‘Sweet Charlie’ and ‘Frange’ with poor comprehensive traits should not be planted. Thirteen strawberry varieties were ordered based on C_i value, as follows: ‘Yanli’>‘Bennisia’>‘Benihope’>‘Chaozao’> ‘Moghave’>‘Sachinoka’>‘Red Pearl’> ‘Tochiotome’>‘Miyamoto’>‘Flange’>‘Sweet Charlie’>‘Toyonoka’>‘Stella’. New strawberry cultivars ‘Yanli’ and ‘Bennisia’ that had moderate plant types, high yields, high fruit hardnesses, high contents of soluble sugar and disease resistances could be demonstrated and promoted in Guangxi region.
