Embodiment 1

[0053] The experiment was carried out in the insect laboratory of the Maize Research Institute of the Guangxi Academy of Agricultural Sciences, with Rongshu 819 provided by the Fuzhou Institute of Agricultural Sciences as the control variety, and Quanshu 17 provided by the Quanzhou Institute of Agricultural Sciences in Fujian Province as the tested variety. The control variety and the tested variety of intact fresh sweet potato without pest pollution were selected, and the weight of each potato piece was between 150 and 200g.

[0054] (1) Place 3 pieces of banyan potato 819 and 17 spring potatoes in each insect box in the laboratory, and repeat 3 times. A total of 9 pieces of banyan potato 819 and spring potato 17 are placed in each insect box. The indoor temperature is 27±1°C and the humidity is 85°C. %, light: white / black=0h / 24h;

[0055] (2) In step (1), in the insect-raising box with potato pieces, each inoculates 5 pairs of strong weevil beetle adults collected from the n...

Embodiment 2

[0064] The experiment was carried out in the insect laboratory of the Maize Research Institute of Guangxi Academy of Agricultural Sciences. The control variety was Banyan 819 provided by Fuzhou Agricultural Science Research Institute, Guangshu 214 provided by Guangdong Academy of Agricultural Sciences, and Fujian Provincial Crop Research Institute. The Fushu 604 and Pushu No. 32 provided by Puning Agricultural Science Institute are the tested varieties. The control variety and the tested variety of intact fresh sweet potatoes without pest pollution are selected, and the weight of each potato block is between 150 and 200g.

[0065] (1) Place 3 pieces of Rongshu 819, Guangshu 214, Fushu 604, and Pushu 32 in each insect box in the laboratory, and repeat 3 times. 9 blocks, indoor temperature 27±1℃, humidity 85%, light: white / black=0h / 24h;

[0066] (2) In step (1), in the insect-raising box with potato pieces, each inoculates 5 pairs of strong weevil beetle adults collected from th...

Abstract

The invention discloses an anti-weevil sweet potato identification method. The anti-weevil sweet potato identification method comprises the steps that 1, compatible varieties and tested varieties of sweet potato tubers are respectively arranged in weevil rearing boxes; 2, weevil adults are inoculated; 3, the open ends of the weevil rearing boxes are covered by meshy covers; 4, the harm situations of sweet potato peels and sweet potato pulp of the compatible varieties and tested varieties of sweet potato tubers are surveyed on the 18th-25th days after inoculation, and the harm levels of the sweet potato peels and the sweet potato pulp are recorded; 5, the sweet potato peel harm index, the sweet potato peel harm index reduction rate, the sweet potato pulp harm index and the sweet potato pulp harm index reduction rate are calculated; 6, the varieties of anti-weevil sweet potatoes are identified according to the sweet potato peel harm index reduction rate and the sweet potato pulp harm index reduction rate. The varieties of anti-weevil sweet potatoes can be quickly and accurately identified by means of the identification method, therefore the identified varieties of anti-weevil sweet potatoes can be reliably subjected to conventional breeding, selection and improvement by adopting a modern biotechnology and can be widely popularized and planted, and accordingly huge economic benefit is obtained.

Description

technical field [0001] The invention relates to an identification method of pest-resistant sweet potatoes, in particular to an identification method of small weevil-resistant sweet potatoes.
