Description
The productivity and persistence of Stylosamhes hamata cvs, Verano and Amiga and S. scabra cv. Seca were compared in small swards in 20 dry tropical environments over periods of 2-4 years, For consistently high production Verano and Amiga appear to require tropical environments with >760 mm average annual rainfall even though they survive in regions with 500 mm. Seca is much more widely adapted than S. hamata, being highly productive and drought resistant in tropical and subtropical environments, but will not survive lieavy frosts. The opportunities for further plant improvement through selection within these species is described. However, the most promising opportunities may occur in an unidentified species known here as S. aff. scabra, which combines the desirable agronomic attributes of S. hamata and S, scabra.
