| contents | Morphometric and Productive Characterization of Nineteen Genotypes from the Colombian Coffea Collection Jhon Wilson Mejía Montoya José Régulo Cartagena Valenzuela Néstor Miguel Riaño Herrera Agrociencias Germplasm Germplasm productivity productivity crop breeding Nineteen genotypes of the Colombian Coffee ( Coffea arabica L.) Collection were characterized through features related to productivity, crown architecture and light interception. The results revealed significant differences among genotypes. Branches and leaves were found to be dominantly plagiophyl. Leaf area (LA) and Leaf area index (LAI) made accession CU1812 (which corresponds to variety Castillo ® ) stand out for its photosynthetically active radiation (PAR) interception and coffee bean production. Likewise, a PAR based cluster analysis allowed dividing the genotypes in three groups. Because of their higher yield, the most outstanding genotypes were Caturra, CU-1812 and Harrar R2. This factor showed correlation with PAR absorption. The current results are useful for future works in coffee breeding programs. 2013 artículo científico 0304-2847 https://www.redalyc.org/articulo.oa?id=179930031004 en http://www.redalyc.org/revista.oa?id=1799 Revista Facultad Nacional de Agronomía - Medellín application/pdf Universidad Nacional de Colombia Revista Facultad Nacional de Agronomía - Medellín (Colombia) Num.2 Vol.66 |
