Embodiment 1

[0042] Set up plot inoculation: Prepare the apple rootstock Vitex vitex, and plant it in plastic flower pots.

[0043] The individual apples of Longdong Begonia, Baleng Begonia, Luanzhuang Shaguo, Zhaojue Mountain Vitex, Xishu Begonia, Shajin Begonia, Chuishi Begonia, Xiaojin Begonia, Shidong Caiping 1# and Cherry Leaf Begonia were respectively tested. Bud grafting or grafting propagation, each individual is guaranteed to proliferate and survive more than 10 plants, and each plant is marked;

[0044] The grafted and multiplied apple seedlings were mailed to Korla, Xinjiang for cultivation;

[0045] When the multiplied seedlings grow to 50cm, compare the multiplied seedlings of each individual in the group, select the ones with the same growth, pick them out and place them in the identification pool to form plot 1, which contains each individual of the group; Select the ones that meet the height of 50cm to form plots 2, 3, 4...; the ones that are not high enough continue to gr...

Abstract

The invention belongs to the technical field of apple disease resistance identification, and particularly relates to a method for identifying apple fire blight resistance by utilizing field plots. The method comprises the following steps that multiple varieties of apple individuals to be identified are propagated to obtain propagated seedlings; and when the growth height of the propagated seedlings reaches 50cm, the propagated seedlings with consistent growth vigor are selected and placed in an identification pool, fire blight bacteria are inoculated, and the fire blight resistance is judged according to the disease index. According to the method for identifying the apple fire blight resistance by utilizing the field plots, apples are subjected to expanding propagation to obtain the expanding propagation seedlings, the expanding propagation seedlings with the consistent growth vigor are selected to construct the plots, then the fire blight bacteria are inoculated, the apple fire blight resistance is identified, so that the detection error caused by inconsistent growth vigor in the apple growth process is avoided, the scientificity of apple fire blight resistance identification is improved, and the problem of poor apple fire blight resistance accuracy is solved.

Description

technical field [0001] The invention belongs to the technical field of apple disease resistance identification, and in particular relates to a method for identifying fire blight resistance of apples by utilizing field plots. Background technique [0002] Fire blight is a bacterial disease caused by Eriwinia amylovora, which is pathogenic to more than 150 species of 36 genera in the Rosaceae family. Death, orchard production reduction, and even devastating disasters in severe cases. As of 2016, fire blight has spread to Kyrgyzstan and Kazakhstan, the origins of apple germplasm resources in Central Asia, and South Korea in East Asia. Identification and screening of apple fire blight resistant resources is crucial. However, the traditional and widely used methods for identifying apple fire blight resistance are not scientifically sound, and the accuracy of the test results is not enough. Therefore, how to improve the accuracy and scientificity of detection is an urgent probl...
