| 【目的】筛选适合基质袋培的高产优质螺丝椒品种，为陕北地区无土栽培辣椒的发展提供依据。【方法】以20个螺丝椒品种（丝路新星、丝路之星、楼兰之星、特早一尺长、中农青螺王子、陇旋339、博收019、HP29017、HP29037、HP29047、HP29082、西域长龙、久保田螺椒王、金椒6号、金椒8号、金椒9号、金椒12号、博陇（37-94）、茎毛802和沃尔斯天萝）为试材，进行基质袋栽培，测定并比较分析各品种辣椒果实的单果质量、果皮厚度、果实长度、维生素C含量、可溶性蛋白含量、游离氨基酸含量、还原糖含量、可溶性总糖含量、硝态氮含量和产量等10项指标，对各指标的相关性进行Pearson分析。同时，采用主成分分析法、TOPSIS分析法、隶属函数分析法和灰色关联度分析法对各品种螺丝椒的产量和品质指标进行评价，经事前一致性检验（Kendall-W）后，采用模糊Borda评价法进行组合评价，以筛选出适合陕北地区基质袋培的螺丝椒品种。【结果】20个螺丝椒品种的单果质量为25.62～52.83 g，以陇旋339最大；果皮厚度为1.58～2.17 mm,以沃尔斯天萝最厚；果实长度为19.42～30.55 cm,以HP29082最长；维生素C含量为276.37～1 058.09 mg/hg,以金椒8号最高；可溶性蛋白含量为0.97～1.61 mg/g,以金椒12号最高；游离氨基酸含量为393.78～969.69 μg/g,以沃尔斯天萝最高；还原糖和可溶性总糖含量分别为3.82%～6.65%及9.87%～13.91%，均以博收019最高；硝态氮含量在各品种间无显著性差异；产量为9 625.98～84 600.00 kg/hm2,以丝路新星最高。4种单一综合评价方法的评价结果存在差异，主成分分析法的评价结果与其他分析方法评价结果的相关性较弱，其余3种单一评价方法间评价结果的相关系数通过了Kendall-W协和系数事前检验，具有相容性，可进行组合评价。模糊Borda组合评价方法的评价结果通过了事后检验，具有可信性，其评价结果显示排名前5位的螺丝椒品种为丝路新星、HP29047、丝路之星、陇旋339和博收019。【结论】丝路新星、HP29047、丝路之星、陇旋339和博收019为适宜陕北地区基质栽培的螺丝椒品种。 |

| Abstract: |
| 【Objective】This study screened high-yielding and high-quality screw pepper varieties suitable for substrate bag cultivation in Northern Shaanxi to provide basis for the development of soilless cultivation of pepper.【Method】Twenty screw pepper varieties including Silk Road New Star,Silk Road Star,Lou Lan Star,Extra Early One-foot Long,Zhongnong Qingluo Prince,Longxuan 339,Biosow 019,HP29017,HP29037,HP29047,HP29082,Western Long Dragon,Kubota Conch Pepper King,Golden Pe pper No.6,Golden Pepper No.8,Golden Pepper No.9,Golden Pepper No.12,Bolon (37-94),Stem Hair 802 and Vols Tenro were chosen for substrate bag cultivation in this study.The weight of single fruit, pericarp thickness,fruit length,contents of vitamin C,soluble protein,free amino acid,reducing sugar,total soluble sugar,nitrate nitrogen as well as yield were measured and compared.The correlations of indexes were analyzed by Pearson analysis.The yield and quality indexes of each variety were evaluated by principal component analysis,technique for order preference by similarity to ideal solution,membership function analysis and grey relational degree analysis. The results of three single comprehensive evaluations by extant consistency test (Kendall W) were evaluated in combination and the fuzzy Borda evaluation method was used to select varieties suitable for substrate bag culturing in Northern Shaanxi.【Result】The weight of single fruit was 25.62-52.83 g,with the heaviest in Longxuan 339.The pericarp thickness was 1.58-2.17 mm,with Vols Tenro the thickest.The fruit length was 19.42-30.55 cm,with the longest in HP29082.The content of vitamin C was 276.37-1 058.09 mg/hg,and Golden Pepper No.8 was the highest. The content of soluble protein was 0.97-1.61 mg/g,and Golden Pepper No.12 was the highest.The content of free amino acid was 393.78-969.69 μg/g,with the highest in Vols Tenro.Contents of reducing sugar and total soluble sugar were 3.82%-6.65% and 9.87%-13.91%,and Biosow 019 had the highest contents.There was no significant difference in nitrate content among varieties.The yield was 9 625.98-84 600.00 kg/hm2,and Silk Road New Star had the highest value. The results of single comprehensive evaluation methods were different,and the results of principal component analysis method had weak correlations with those of other methods.The correlations among other single evaluation methods passed the Kendall-W test and they were compatible for combined evaluation.The fuzzy Borda combination evaluation method passed tests with good credibility.The obtained top 5 varieties were Silk Road New Star,HP29047,Silk Road Star,Longxuan 339 and Biosow 019.【Conclusion】Silk Road New Star,HP29047,Silk Road Star,Longxuan 339 and Biosow 019 were suitable for substrate cultivation in Northern Shaanxi. |
