OLIVERA, Yuseika  y  OLIVARES, J. Evaluation and selection of accessions in a Teramnus spp. collection.: Establishment stage. Pastos y Forrajes [online]. 2009, vol.32, n.2, pp. 1-1. ISSN 0864-0394.

A collection of 50 Teramnus spp. accessions was evaluated, with the objective of selecting those with better performance during the establishment stage. The study was conducted at the EEPF «Indio Hatuey», on a compacted Ferralitic Red soil. For that this stage was divided in two phases, the first one corresponded to monitoring during the time the plants were kept in bags and the second phase since they were transferred to the field until such stage was completed; in this second phase cover was estimated every 15 days and the following scale was used: 1= 10-20% covered area (very little covered), 2= 21-40% covered area (little covered), 3= 41-60% covered area (partially covered), 4= 61-80% covered area (covered) and 5= >80% area covered (well covered). When monitoring in the fist stage of establishment it was observed that 98% was sown in bags (49 accessions), because seed was not obtained from one of them; from these accessions only 67,3% (33 accessions) could be transferred to the field, because the rest (16 accessions) died before reaching the height established for that purpose. From the plants transferred to the field five died during the first 15 days of evaluation, for which 28 remained. From them, 67,8% (19 accessions) showed the best cover values during the establishment, for which to perform their evaluation during the exploitation stage is recommended.
