Abstract:

The development of new high and stable-yield Vernicia fordii (tung oil tree) varieties is of great significance for the high-quality development of the tung oil industry. ‘Yahong 1’ is a new variety of tung oil tree developed from natural variation of the ‘Duinian tung tree’ in Guizhou Province, China. It is a purely female plant with multi-spike racemes. The fruits are round, borne on short stalks, with 15?20 fruits per branch and an average of 4.8 seeds per fruit. The seeds are broadly ovate in shape. Each fruit weighs 49.0 g on average, and a single plant produces 36.67 kg of fruit, equivalent to 10.0 kg of dry tung seeds per plant. ‘Yahong 1’ variety grows rapidly, demonstrates high and stable productivity, and exhibits tolerance to poor soils and seasonal droughts, making it an excellent new variety for large-scale tung oil production.

Key words: Vernicia fordii, female plant, high yield, variety
