Abstract
The growth performance and fruiting quantity of different pecan varieties introduced to southern Sichuan were investigated. The results showed that the pecans grew sturdily and developed normally. The male and female flowering periods of pecans were from April 6 to May 8. After the grafted seedlings were planted, most varieties began to fruit at 4 years, and the highest yield per plant reached 1.24 kg at 5 years. Preliminary analysis indicated that the pecan had good adaptability to the climate environment in southern Sichuan, and was suitable for planting and developing. In the short term, No. 29, Weston, and No. 761 could be used as the main planting varieties. No. 21 and No. 35 could be used as the pollination varieties to further expand the scope of regional trials.
