中文摘要: |
本试验研究了抗蚜株率?感蚜指数和改进的感蚜指数3种评价方法对14个苜蓿品种抗蚜评价的影响?结果表明:以抗蚜株率为标准, ‘甘农9号’抗性最好; 以感蚜指数为标准, ‘阿尔冈金’抗性最好?而采用改进后的感蚜指数评价方法可将14个苜蓿品种分为7个等级, 其中‘WL-319’为高感品种, ‘巨能Ⅱ’为感虫品种, ‘新牧4号’‘甘农5号’‘WL-354’‘WL-363’为低感品种, ‘新牧1号’为中间品种, ‘甘农9号’为低抗品种, ‘MF4020’为中抗品种, ‘中苜1号’‘WL-343’‘阿尔冈金’‘苜蓿王’‘SK3010’为高抗品种?改进后的感蚜指数评价方法符合“1±0.1”等差数列分级标准, 使不同抗性级别符合正态分布, 具有统计学意义?同时, 该方法充分考虑了天敌对蚜虫发生量的影响, 在生产实践中具有重要的推广应用价值? |
英文摘要: |
Effects of three methods on resistance evaluation of 14 alfalfa varieties to aphid were investigated. The results show that the resistance of ‘Gannong 9’ is the best with the evaluation standard of the rate of resistant plants, and the resistance of ‘Algonquin’ is the best with the evaluation standard of aphid index. Based on the improved aphid index evaluation method, 14 alfalfa varieties were divided into 7 grades, ‘WL-319’ as high susceptible, ‘Juneng Ⅱ’ as susceptible, ‘Xinmu 4’‘Gannong 5’‘WL-354’and‘WL-363’as low susceptible, ‘Xinmu 1’as tolerant, ‘Gannong 9’ as low resistant; ‘MF4020’ as moderately resistant, ‘Zhongmu 1’ ‘WL-343’ ‘Algonquin’ ‘Alfaking’ and ‘SK3010’ as high resistant. The improved aphid index evaluation method conforms to the grading standard of “1±0.1” arithmetic sequence, making different resistance levels conform to normal distribution, with statistical significance. At the same time, this method takes into full account the influence of aphid amount, which is of important value in production practice. |
