四川烤烟区试新品种综合分析与评价

Comprehensive Analysis and Evaluation of New Flue-cured Tobacco Varieties in Sichuan Regional Trials

本研究利用AHP法对2016年四川省烟草区试10个典型评价指标进行权重分配,为DTOSIS法提供合理权重,利用隶属函数法优化DTOPSIS法中对化学评价指标的无量纲化处理,并通过DTOPSIS法对参试品种进行综合评价。结果显示,产量、上等烟比例、产值、叶数、茎围、株高、烟碱含量、总糖含量、钾含量、黑胫病病情指数的权重分别为0.090 2、0.235 1、0.301 4、0.035 1、0.021 7、0.021 7、0.057 1、0.035 1、0.0351和0.167 6。新品种在川西南种植区综合评价排序为‘云烟87’>‘SCT01’>‘红花大金元’>‘K326’>‘09011’>‘X4’>‘X3’;在川南种植区为‘K326’>‘云烟87’>‘09011’>‘SCT01’>‘X3’>‘X4’;在川北种植区为‘09011’>‘云烟87’>‘X4’>‘SCT01’>‘X3’。本研究结果表明:‘SCT01’可作为良种在川西南种植区试验示范,‘09011’有作为良种在川北种植区进行试验示范的潜力,而‘X3’和‘X4’的栽培措施需要改进。本研究为四川烤烟新品种筛选、鉴定和推广提供科学依据,有助于丰富烤烟新品种的评价体系。

Analytic hierarchy process(AHP) was used to distribute the weight of 10 evaluation indexes of flue-cured tobacco varieties of regional trials in Sichuan province in 2016 for dynamic technique for order preference by similarity to ideal solution(DTOPSIS), membership function was used for optimizing dimensionless treatment of chemical evaluation indexes of DTOPSIS, and then DTOPSIS was used for comprehensive evaluation of varieties. The weight of yield, proportion of superior tobacco, output value, leaf number, stem circumference,plant height, nicotine content, total sugar content, potassium content and black shank disease index was 0.090 2,0.235 1, 0.301 4, 0.035 1, 0.021 7, 0.021 7, 0.057 1, 0.035 1, 0.035 1 and 0.167 6, respectively. The comp-rehensive evaluation order of new varieties in planting areas in Southwest Sichuan was ’Yunyan87’ >’SCT01’ >’Hongda’ >’K326’>’09011’>’X4’>’X3’, the order in South Sichuan was ’K326’>’Yunyan87’>’09011’>’SCT01’>’X3’>’X4’, and the order in North Sichuan was ’09011’>’Yunyan87’>’X4’>’SCT01’>’X3’. The results of this study showed that further experiments and demonstrations of ’SCT01’ could be conducted in plant areas in Southwest Sichuan, ’09011’ has the potential to be used as a good variety in plant areas in North Sichuan, and the corresponding cultivation measures of ’X3’ and ’X4’ should be improved. This research would provide scientific basis for the screening,identification and promotion of new flue-cured tobacco varieties, and enrich the evaluation system of new flue-cured tobacco varieties.
