Resumen

En el período 2006–2011 en 2 sitios del noreste de Tailandia (Ubon Ratchathani y Amnart Charoen) fueron evaluadas por su producción de forraje y calidad nutritiva 43 líneas nuevas de híbridos de Brachiaria, incluyendo el cultivar (cv.) Mulato II como testigo, procedentes del CIAT. Los parámetros evaluados fueron producción de materia seca (MS) en épocas lluviosa y seca, relación hoja:tallo, concentración de proteína cruda (PC) y niveles de fibra detergente ácido (FDA) y fibra detergente neutro (FDN)]. En la época seca, ninguna de las líneas mostró en forma consistente una producción de MS y relación hoja:tallo superiores que cv. Mulato II. En las épocas lluviosas, 14 líneas produjeron más MS que Mulato II, pero sólo en una época lluviosa cada una. El cultivar Mulato II produjo forraje con alta relación hoja:tallo en todas las épocas. Varias de las líneas presentaron concentraciones de PC significativamente mayores y menores niveles de FDA y FDN que cv. Mulato II, pero su producción de forraje y la relación hoja:tallo fueron inferiores. Las líneas BR02/1718, BR02/1752, BR02/1794 y BR02/0465 alcanzaron la protección de obtención vegetal (Plant Variety Rights) en 2011.

Keywords: Cayman, Cobra, crude protein, dry matter yields, forage regrowth,  Mulato II.

Biografía del autor/a

Michael D. Hare, Ubon Forage Seeds, Faculty of Agriculture, Ubon Ratchathani University, Ubon Ratchathani, Thailand.

Michael Hare has been involved with seed production of tropical and temperate forage grasses and legumes for almost four decades in Thailand (tropical) and New Zealand (temperate). In Thailand Michael started large scale machine harvesting of Townsville stylo and Verano stylo in the 1970s and later was involved in a village farmer seed programme of various species which continues until this day. From 1984 to 1994 Michael worked as a herbage seed scientist at Grasslands Division, DSIR, Palmerston North, New Zealand, researching seed production problems on a wide range of temperate species. Since 1994, Michael has worked at Ubon Ratchathani University in Thailand, researching seed production of tropical forages and starting a new village seed programme with Tropical Seeds, a subsidiary of a Mexican seed company, Grupo Papalotla. This programme contracts over 1000 village farmers in Thailand and Laos to produce seed of Mulato II and Cayman hybrid brachiarias, Mombasa and Tanzania guinea grasses, Ubon paspalum and Ubon stylo. Seed is currently being exported to countries in Central America, the South Pacific, other parts of Asia and now Africa. Michael conducts research trials on the above species and is involved in final evaluation of new hybrid brachiaria accessions from CIAT for which Grupo Papalotla has the production rights. Michael is a professor in the Faculty of Agriculture, Ubon Ratchathani University and recently became a Fellow of the Tropical Grassland Society of Australia Inc. He has been author or co-author of 130 papers on various aspects of seed and forages in both temperate and tropical pastures.
