Citación: | Genetic Resources and Crop Evolution 51(8): 883-894 (2004) | Resumen: | The phenotypic variation found in four common bean (Phaseolus vulgaris L.) complex primitive landraces, among a group of accessions collected in Northwestern Argentina in several missions is described, with particular attention to the wide diversity found in some small areas. It is presented a hypothesis about the maintenance of such diversity in bean mixtures or complex primitive landraces that grow close to their wild relative. Wide diversity regarding to seed type and plant characteristics was displayed by the landraces MCM-SV (composed of 11 lines), MCM-292 (14 lines), MCM-298 (5 lines) and VAV-3716 (14 lines). Food uses of dry seed and fresh pod seemed to be more relevant than the aesthetic use although all of them were presumably considered by humans for centuries resulting in the current phenotypes of these complex primitive landraces. Additionally, some weedy types (intermediate between wild and domesticated types) were detected in the landracesMCM-292 and MCM-298. The four complex landraces described consisted of highly diverse mixtures and they could play a role in breeding to enlarge the genetic basis of domesticated bean varieties belonging to the Andean gene pool. | Descripción: | 12 páginas, 1 figura, 7 tablas. | Versión del editor: | http://dx.doi.org/10.1007/s10722-005-1934-0 | URI: | http://hdl.handle.net/10261/39351 | DOI: | 10.1007/s10722-005-1934-0 | ISSN: | 0925-9864 | E-ISSN: | 1573-5109 |
