Abstract：The seeds of Torreya grandis Fort. ex Lindl are a peculiar nut fruit in China. In order to effectively protect, develop and utilize the germplasm resources of this species, a systematic investigation of its germplasm resources in Zhejiang, Anhui, Jiangxi and Fujian provinces was conducted through field investigation, specimen collection, indoor seed examination and ingredient analysis. The results showed that the resources of T. grandis was unevenly distributed and only conserved well in a few regions. The single seed weight, single kernel weight, kernel rate, kernel shape index and nutrient content varied greatly among individual trees, but some superior individual trees in integrated traits and quality had discovered, which could be grouped into seven major varieties and types. Those individual trees with seeds of integrated good traits, good quality, special traits or potential utilization value should be collected and preserved, especially focusing on those of high and stable yield and special high traits. The old trees or their population should be protected.
