AI Technical Summary

Technical Problem

Current technologies rely on physicochemical testing after fruit ripening to assess the oil yield of thin-shelled pecans, resulting in long breeding cycles, high costs, and resource waste. Furthermore, the lack of precise molecular markers for breeding makes it difficult to meet the market demand for high-oil varieties.

Method used

We developed SNP molecular markers related to the oil yield of thin-shelled pecans, identified SNP sites using high-throughput sequencing technology, designed specific primer sets for detection, and constructed MAS breeding and GS models to achieve precise seedling prediction and targeted breeding.

Benefits of technology

It enables precise seed selection during the seedling stage, reduces breeding costs, improves the efficiency of genetic improvement of varieties, and provides full-chain technical support from variety cultivation to commodity circulation.
