Abstract:

2009-4, named as Flemingia macrophylla cv. Reyan No. 34, was bred after 12 years of several successive individual selection and propagation of original Flemingia macrophylla (Willd.) Prain introduced from International Center for Tropical Agriculture (CIAT). Comparative trial research showed that 2009-4 had high-yield, rich resistance, stronger stability and uniformity. DM yield was 15 021.30 kg/hm2 during variety comparison experiment, 51.96% and 78.10% very significantly higher than that of the parent ‘CIAT17407’ and check variety Tephrosia candida. The flowering period was earlier, generally in the middle of August, 30 days earlier than the control and 8 days later than the parent. The plant survival rate was significantly higher than that of the control and parent. It had a developed root system and drought resistance, and had the characteristics of high and stable yield during dry season at rainfall 755 mm above regions. It also had high adaptability to strong acid soil with pH 4.0-5.0, and could improve low fertilizer soil and poor soil. 2009-4 is suitable for the cultivation of tropical and subtropical areas in China, especially for the large-scale promotion of South China.
