The Preliminary Research of the Selectivity of Tea Aphids on Germplasms Suitable for Processing Oolong Tea

Tea Institute of Fujian Academy of Agricultural Sciences, Fu'an, Fujian 355015, China

摘要

摘要: 连续2年调查了田间及网室茶蚜在不同品种上的数量动态,分析茶蚜对福建14个适制乌龙茶品种的选择性。结果表明:①田间及网室茶蚜对不同品种的选择性存在显著差异,两年份之间茶蚜对不同品种的选择性不完全一致,但网室不同品种两年份之间的有蚜梢率、蚜情指数、蚜量比值一致性均大于田间两年份之间的一致性;②网室不同品种有蚜梢率、蚜量比值、蚜情指数3个指标随时间变化的趋势基本一致,用这3个指标来衡量茶蚜对不同品种的选择性是可行的;③以网室不同品种两年份有蚜梢率、蚜量比值、蚜情指数为指标,对14个适制乌龙茶品种进行聚类分析,结果表明白鸡冠、丹桂各自为一类,为易感蚜虫类型,毛蟹、白牡丹聚在同一类,为排趋蚜虫类型,其他品种属于两者中间类型。

Abstract: The population dynamics of aphids on different cultivars were investigated in the field and net in two consecutive years respectively, and the selectivity of tea aphid on fourteen tea cultivars which are suitable for processing oolong tea in Fujian province was compared. The results showed that: ①The selectivity of tea aphid was significantly different on each cultivars in the field and net, and it was not consistent with each other in two years, but the consistency on the aphid shoot rate(%), aphid number ratio and aphid sentiment index in net were larger than that in the field in two years. ②It is feasible to use three indicators of aphid shoot rate(%), aphid number ratio, aphid sentiment index to measure the selectivity of tea aphid on different tea cultivars, for the trends on different cultivars were consistent with the changes of time basically. ③Clustering analysis of fourteen tea cultivars suitable for processing oolong tea was conducted based on aphid shoot rate(%), aphid number ratio and aphid sentiment index, and the changes of which in net was used as indicators in two years. Our results suggest that Bai Ji Guan and Dan Gui belong to a category respectively, which are susceptible to tea aphid; Mao Xie and Bai MuDan belong to the same category, which are resistance to aphid; and other cultivars belong to the intermediate type.
