AI Technical Summary
Existing rubber tree variety identification methods rely on morphological characteristics, which are easily affected by environmental factors, leading to unstable identification results. In addition, high-throughput sequencing methods are costly and difficult to accurately distinguish the 'Yunyan 272' variety, which can easily cause variety confusion.
Using molecular markers located at bases 10110474–10110618 on chromosome CM021232_1, specific primer pairs were designed, and accurate identification of the 'Yunyan 272' variety was achieved through PCR amplification and Sanger sequencing. A simple kit is provided for the operation.
It has enabled the specific identification and accurate characterization of the 'Yunyan 272' variety, improved the accuracy of identification, optimized variety selection and regional suitability assessment, and promoted the scientific nature of rubber tree planting and breeding.
