| description | In order to study gene flow between common wild and cultivated cultivated bean, the rate of allogamy was estimated in a location where wild common bean grows naturally and at an experimental station. In 2004, natural outcrossing between wild Mexican bean G23511A (Phaseolus vulgaris L.) and white cultivar PAN68 was estimated at Fabio Baudrit Experimental Station of the University of Costa Rica in Alajuela. Two experimental plots were sown; each one had two blocks of ten rows of PAN68 (15m long and 0,6m spaced). Between blocks and at their upper border, three rows of wild Mexican common bean were sown as pollen donors. Each of the rows and plants in the white blocks was numbered. In 2005 and 2006 in Quircot, Cartago, where wild common bean grows naturally, plants of common bean (Vainica de Palo) were sown in six locations adjacent to wild common bean populations. In both locations, flowering of wild and cultivated bean was coincident. All seeds from assays were harvested and germinated in seedlingtrays, estimating the rate of allogamy through the color of the hipocotyl (purple), which indicates what seedlings were crossed. In Alajuela, natural crossing ranged from 0,007 to 0,028 %, whereas in Quircot from 0 to 0,199 %. |

Con el objetivo de analizar el flujo de genes entre frijol común silvestre y cultivado, se determinó el porcentaje de alogamia en condiciones naturales de crecimie nto del frijol silvestre y en estación experimental. En el 2004 se evaluó el cruzamie nto natural entre frijol silvestre mexicano G23511A (Phaseolus vulgaris L.) y la línea blanca PAN 68, en la Estación Experimental Fabio Baudrit de la Universidad de Costa Ri ca en Alajuela. Para ello se sembraron dos parcelas experimentales; cada una constó de dos bloques de PAN 68 de 10 surcos (15 m de largo y espacia dos 0,6 m). Entre los bloques y en el borde superior de los mismos, se sembraron tres surcos de frijol silvestre como donantes de polen. Se numeraron las hileras y las plantas de cada una en los bloques de frijol blanco. En Quircot de Ca rtago (área donde crece en forma natural P. vulgaris silvestre), en el 2005 y 2006, se sembraron plantas de frijol comercia l (Vainica de Palo) a lo largo de seis sitios junto a las poblaciones de frijol silvestre. En ambas localidades la floración de silvestres y comerciales fue coincidente. Se cosechó toda la semilla de los ensayos y se germinó en bandejas, determinando el porcentaje de alogamia por medio del color morado del hip ocotilo, indicativo de aquellas plántulas cruzadas. En Alajuela el porcentaje de cruza varió entre 0,007 y 0,028 %; mie ntras que en Quircot, entre 0 y 0,199 %. 2009 2014-10-02T08:33:36Z 2014-10-02T08:33:36Z Journal Article https://hdl.handle.net/10568/44331 es Open Access Chaves-Barrantes, N.F., R.
