Abstract

The invention discloses a qualitative PCR detecting method for transgenic insect-resistant herbicide-tolerant rice G6H1 and derived varieties thereof, and belongs to the qualitative detecting field of transgenic rice varieties. The invention firstly discloses 8 pairs of specific PCR detecting primer pairs for detecting the transgenic insect-resistant herbicide-tolerant rice G6H1 and derived varieties thereof. Based on this, the invention establishes a qualitative PCR detecting method for the transgenic insect-resistant herbicide-tolerant rice G6H1 and derived varieties thereof, which is strong in specificity and high in sensitivity. The invention further discloses a qualitative PCR detecting kit for the transgenic insect-resistant herbicide-tolerant rice G6H1 and derived varieties thereof. An experiment for specificity, sensitivity and detection limit proves that the qualitative PCR detecting method for the transgenic insect-resistant herbicide-tolerant rice G6H1 variety is strong in specificity, high in sensitivity and good in detection limit, and applicable to qualitative detection of the transgenic G6H1 rice and derived varieties thereof.

Description

technical field [0001] The present invention relates to a qualitative PCR detection method for transgenic rice varieties, in particular to qualitative PCR detection primers, a qualitative detection method and a detection kit for transgenic insect-resistant and herbicide-resistant rice G6H1 and its derivative varieties, belonging to transgenic insect-resistant and herbicide-resistant rice G6H1 and The field of qualitative PCR detection of its derivatives. Background technique [0002] The transgenic insect-resistant and herbicide-tolerant rice variety G6H1 is obtained by introducing the codon-optimized insecticidal gene HJC-1 and glyphosate-resistant gene G6 into the cultivated rice variety "Xiushui 110". The total length of the inserted sequence is about 10.2kb ( figure 1 ). HJC-1 is a fusion gene of Cry1Ab and Vip3H. The fusion of these two genes has a broader spectrum of insecticidal ability against Lepidoptera pests. G6 is a novel 5-enolpyruvate 3-phosphate synthase ge...
