摘要
为科学评价大葱品种的性状,引进国家特色蔬菜产业技术体系专家新选育的8个大葱品种进行品种比较试验,采用主成分分析、相关性分析对不同大葱品种的株高、葱白长、茎粗、最大叶长、最大叶宽、功能叶数、叶片颜色、叶片蜡粉等8个农艺性状和产量进行综合评价。结果表明:根据8个农艺性状的主成分贡献率对各大葱品种进行综合评价,其中得分排名前3的品种分别为安葱3号、YS09和YS08;其中,安葱3号产量最高,其次为YS08和YS09,3个品种均显著高于对照品种;将综合得分与8个表型性状、产量等指标进行相关性分析,发现产量和综合得分与株高、最大叶长呈极显著正相关,与葱白长呈显著正相关;产量与综合得分呈极显著正相关。综上,安葱3号的综合农艺性状得分高于其他处理,且667 m^(2)产量最高,为8887.49 kg;其植株高大(83.84 cm)、葱白长(11.48 cm)且粗(266 mm),生长速度快,可选择推广种植。
In order to evaluate the characteristics of welsh onion vareities scientifically,eight vareities of welsh onion newly selected by experts of national characteristic vegetable industry technical system were introduced to carry out comparative experiment.Principal component analysis and correlation analysis were used to comprehensively evaluate eight agronomic traits and yield of different vareities,including plant height,bulb length,stem diameter,maximum leaf length,maximum leaf width,functional leaf number,leaf color and leaf wax powder.The results showed that based on the principal component contribution rates of eight agronomic traits,the top three vareities were'Ancong No.3''YS09'and'YS08',with'Ancong No.3'had the highest yield,followed by'YS08'and'YS09',and the yield of all three vareities were significantly higher than that of the control.The correlation analysis between comprehensive score and eight agronomic traits,yield and other indicators showed the yield and comprehensive score was extremely significantly and positively correlated with plant height and maximum leaf length,and significantly positively correlated with bulb length,and the yield was extremely significantly and positively correlated with the comprehensive score.Overall,the comprehensive agronomic trait score of'Ancong No.3'was higher than other treatments,and the yield was the highest,reaching 8887.49 kg per 667 m^(2).Its plant was tall(83.84 cm),bulb was long(11.48 cm)and thick(266 mm),and its growth speed was fast,so it could be extended for planting.
