摘　　要：从国际热带农业中心引进的大叶千斤拔,经连续多次的单株选择和原原种扩繁,历时12 a,初步筛选出2009-4大叶千斤拔具有产量高、抗性丰富、较强的稳定性和一致性等特点,命名为‘热研34号’大叶千斤拔;品比干草产量15 021.30 kg/hm^(2),比亲本‘CIAT17407’增产51.96%,比对照品种‘山毛豆’增产78.10%;开花期较早,一般在8月中旬开始始花期,比对照提前30 d,比亲本推迟8 d;植株存活率显著高于对照和亲本;根系发达,耐干旱,在年降水755 mm的地区具有高产稳产的特点;对土壤的要求不严,能在pH 4.0~5.0的强酸性土壤和贫瘠的砂质土壤上良好生长。适合我国热带、亚热带地区种植,尤其适于华南地区大面积推广。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 15021.30 kg/hm^(2) 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.
