[en] The genetic diversity among the main local landraces and commercial cultivars of P. vulgaris L. cultivated in Greece, was estimated by studying the morphological, agronomical and physicochemical traits along with molecular data analysis using random amplified polymorphic DNA (RAPD markers). Cluster analysis was conducted on similarity estimates using the UPGMA algorithm. Application of cluster analysis resulted in a dendrogram representing the genetic relationship among landraces and main bean cultivars grown in Greece. A wide genetic variation was observed among collected local bean landraces in morphological characteristics such as seed color, seed size and growth habit. According to agronomic performance, significant differences were found in number and weight of pods per plant. Variation in protein and fat content among landraces and commercial cultivars was also detected. Moreover, in some landraces like Kastoria and Byzitsa M/M extremely high values for protein content (28.6% and 27.0% respectively) were recorded. Such values were greater than the average protein content previously recorded for other cultivars of this species. Genetic similarity estimated from molecular analysis with RAPDs, seemed not to be related with the seed morphological characteristics and agronomic performance. Only qualitative parameters like growth habit and occasionally geographical origin of landraces were positively correlated with the molecular classification. Local bean landraces were classified in three subgroups whereas the commercial cultivars formed another separate group underlining the narrow genetic base of cultivars.

[es] Se estim&oacute; la diversidad gen&eacute;tica entre las principales variedades aut&oacute;ctonas y cultivares comerciales de P. vulgaris L. cultivados en Grecia, mediante el estudio de caracteres morfol&oacute;gicos, agron&oacute;micos y fisicoqu&iacute;micos, junto con el an&aacute;lisis de datos moleculares utilizando marcadores RAPD (amplificaci&oacute;n al azar de DNA polim&oacute;rfico). Se llev&oacute; a cabo an&aacute;lisis de cluster (CLA) estimando la similitud con el algoritmo UPGMA, obteniendo un dendrograma que representa las relaci&oacute;nes gen&eacute;ticas entre las principales variedades locales y comerciales de alubia cultivadas en Grecia. Se observ&oacute; una amplia variaci&oacute;n entre variedades locales de alubia en caracter&iacute;sticas morfol&oacute;gicas tales como color y tama&ntilde;o de la semilla y h&aacute;bitos de crecimiento. En lo que respecta al comportamiento agron&oacute;mico, se encontraron diferencias significativas en el n&uacute;mero y el peso de vainas por planta. Tambi&eacute;n se observ&oacute; variaci&oacute;n en los contenidos de prote&iacute;na y de grasa. Adem&aacute;s, se encontraron valores extremadamente altos de contenido en prote&iacute;na en algunas variedades como Kastoria y Byzitsa M/M (28,5% y 27,0%, respectivamente), que son mucho mayores que la media registrada previamente para cultivares de esta especie. La semejanza gen&eacute;tica estimada mediante el an&aacute;lisis molecular de RAPDs no parece estar relacionada con las caracter&iacute;sticas morfol&oacute;gicas de la semilla ni el comportamiento agron&oacute;mico. S&oacute;lo los par&aacute;metros cualitativos como el h&aacute;bito del crecimiento y el origen geogr&aacute;fico de las variedades locales mostraron relaci&oacute;n con su clasificaci&oacute;n molecular. Las razas locales de alubia se clasificaron en tres subgrupos, mientras que los cultivares comerciales formaron otro grupo separado que refleja una estrecha relaci&oacute;n gen&eacute;tica entre cultivares.
