Two new hybrid varieties ＇Los Chinese catalpa 1＇（8-5 × 6-7） and ＇Los Chinese catalpa 2＇（8-5 × Long fruit Chinese catalpa） with successive years seedling test and the national multi-point afforestation test were bred. The material parents were from Chinese catalpa plantations during ＇seventh five-year＇ plan by Luoyang Forestry Research Institute. Afforestation four years, Compared with Gold-rimmed Chinese catalpa and parent 8-5, the average tree height and DBH of ＇Los Chinese catalpa 1＇ increased by 76.1%. 46.1%. 35.9%. 13.9%respectively; ＇ Los Chinese catalpa 2＇ raised 49.8% . 56.6%. 15.7%. 22.1%respectively They have passed the evaluation of Henan variety identification committee in December 2010, Two varieties are the most productive potential of Chinese catalpa with the characteristics of fast growing, superior wood properties, strong resistance, wide adaptability. They are suitable for widely cultivated in northern, central, northwest, southwest of China.
