Conceptos basicos para el mejoramiento del frijol por hibridacion
The basic concepts of the genetic improvement of beans through hybridization are described. In general, the breeding process involves the following phases: (1) development of exptl. lines, (2) evaluation of exptl. lines and identification of new cv., and (3) commercialization of new cv.

| description | The basic concepts of the genetic improvement of beans through hybridization are described. In general, the breeding process involves the following phases: (1) development of exptl. lines, (2) evaluation of exptl. lines and identification of new cv., and (3) commercialization of new cv. The main aspects that should be considered in the development of exptl. lines as well as the most common breeding methods used in beans (modified pedigree, mass- pedigree, and backcrossing) are described. The evaluation of exptl. lines and the identification of new cv. are carried out in 3 or more steps: adaptation nurseries, preliminary yield trials, and regional yield trials. For the commercialization of new cv. the newly identified materials are registered, multiplied, and distributed. (CIAT) |

(CIAT) Se describen los conceptos basicos de mejoramiento genetico del frijol por hibridacion. En general, el proceso de mejoramiento involucra las siguientes fases: 1) el desarrollo de lineas exptl., 2) la evaluacion de las lineas exptl. y la identificacion de los nuevos cv. y 3) la comercializacion de nuevos cv. Se describen los aspectos importantes que deben considerarse en el desarrollo de las lineas exptl. y los metodos de mejoramiento mas comunes utilizados en el frijol (pedigri modificado, masal-pedigri y retrocruzamiento). La evaluacion de las lineas exptl. y la identificacion de nuevos cv. se realizan en 3 o mas etapas: viveros de adaptacion, ensayos preliminares de rendimiento y pruebas regionales de rendimiento. Para la comercializacion de nuevos cv., los materiales recien identificados se registran, se multiplican y se distribuyen.
