Abstract

OVALLE M., Carlos et al. Cauquenes-INIA, a new Chilean cultivar of burr medic (Medicago polymorpha) for Mediterranean dryland areas. Agric. Téc. [online]. 2001, vol.61, n.1, pp.89-92. ISSN 0365-2807.  http://dx.doi.org/10.4067/S0365-28072001000100010.

Cauquenes-INIA is the first cultivar of burr medic (Medicago polymorpha), released by the Cauquenes Experimental Center of the National Agricultural Research Institute (INIA). It was selected from a collection of germoplasm obtained from an expedition through the Mediterranean zone of central Chile, between La Serena (29º 55’ S lat.) and Temuco (38º 47’ S lat.), in 1988. It is an annual forage legume, for subhumid and humid Mediterranean zones, especially appropriate for farming systems where the pasture is rotated with cereals (ley farming systems). It is a semi-precocious cultivar (approximately 100 days from emergence to first flower), with semi-erect growth, yellow flowers, spineless pods and a high percentage of hard seeds. Dry matter production (6570 and 6350 kg DM ha-1) and seed yield (82 and 88 kg ha-1) proved to be similar or superior to Australian cultivars of burr medic available in the national market.

Keywords : Chile; mediterranean climate; forage legume; annual medic; dry matter; seed yield.
