摘要
【目的】探明不同芒果品种对蓟马的抗性及其机理,为芒果抗性品种选育及蓟马的综合治理提供理论参考。【方法】以农业农村部儋州芒果种质圃内的40个芒果品种为材料,采用盘拍法调查不同芒果品种嫩梢上的蓟马虫口密度,以虫量比值法鉴定40个芒果品种对蓟马的抗虫性;观测40个芒果品种的嫩叶颜色、嫩梢密度和嫩梢生长期等性状,分析其对蓟马为害的影响。【结果】40个参试芒果品种中有高抗品种5个、抗虫品种5个、中抗品种8个、感虫品种13个和高感品种9个,各抗性品种的单梢虫量比值分别为0.04~0.10、0.13~0.17、0.22~0.36、0.52~1.47和1.79~4.20,占比分别为12.5%、12.5%、20.0%、32.5%和22.5%。不同嫩叶颜色芒果品种的平均虫口数量排序为锌黄色>铜褐色>古粉红色>黄绿色>紫红色,嫩叶为锌黄色芒果品种的虫口数量最大(10.7头/梢),显著高于其他4种颜色的芒果品种(P<0.05),铜褐色、古粉红色、黄绿色和紫红色的芒果品种之间虫口数量差异不显著(P>0.05,下同);芒果单株嫩梢密度与蓟马虫口密度呈正相关(r=0.044),但未达显著水平;不同嫩梢生长期芒果品种的平均虫口密度排序为初期>中期>末期,但3个不同生长时期的芒果嫩梢虫口密度差异不显著。【结论】Jan-78、缅甸3号、红晕芒、河口本地芒和肯特为高抗品种,具有较好的抗蓟马育种潜力,可为今后开展芒果抗蓟马育种提供重要材料。芒果品种的抗虫性与其嫩叶颜色密切相关,锌黄色的嫩叶是芒果蓟马趋于为害的重要因素。
【Objective】To identify the resistance of different mango varieties to thrips and explore the mechanisms underlying the resistance,provide a theoretical basis for breeding resistant mango varieties and developing comprehensive prevention and control methods for thrips.【Method】Forty mango varieties in Danzhou mango germplasm repository of ministry of agriculture and rural affairs were used as tested materials in this study.The thrips density on different mango varieties new shoots were observed with plate-flapping method,and identified the resistance of 40 mango varieties to thrips with number ratio method.The young leaves color,young shoot density and young shoot grow period of the 40 mango varieties were also observed,their effects on the infestation of thrips on mango varieties were analyzed.【Result】Among the 40 mango varieties examined,no variety was immune,5 varieties were highly resistant,5 varieties were resistant,8 varieties were medium resistant,13 varieties were susceptible,and 9 varieties were highly susceptible.The thrip number ratios per shoot of different resistant levels were 0.04-0.10,0.13-0.17,0.22-0.36,0.52-1.47 and 1.79-4.20,with the ratios were 12.5%,12.5%,20.0%,32.5%and 22.5%,respectively.The ranking of thrips density of mango varieties in different young leaves color was zinc yellow>copper brown>antique pink>yellow green>purple red,the mango varieties with zinc yellow leaves had the highest thrips density(10.7 thrips/shoot),which was significantly higher than the other four colors(P<0.05).No significant difference on thrips density was found in different mango varieties with copper brown,antique pink,yellow green and purple red young leaves(P>0.05,the same below).The density of young shoots per plant was positively correlated(r=0.044)with thrips density but did not reach significant level.The ranking thrips density of mango varieties at different young shoot grow periods wasinitial stage>middle stage>terminal stage,but no significant difference on thrips density was found among dif
