CO-SEGREGATION OF RECOMBINANT INBRED LINES OF THE COMMON BEAN TO RACES 65 AND 73 OF Colletotrichum lindemuthianum

摘要

The common bean (Phaseolus vulgaris L.) is one of the most important legumes for direct human consumption (Lin et al. 2008). Anthracnose, caused by Colletotrichum lindemuthianum is the most widespread, recurrent and devastating disease of the common bean in Latin America and Africa (Pastor-Corrales and Tu 1989). The genetic mapping is carried out using segregating populations. Obtaining segregating populations for genetic mapping have been standard practice in the common bean research (Gepts et al. 1993; Blair et al. 2006). These populations have led to detailed studies and promising to greater efficiency in the genetic breeding of the crop worldwide, but have as limitation, the small size (Sanglard et al. 2013). Thus, the objective of this research was to phenotype the recombinant inbred lines (RIL's) population from AND 277 * Ruda cross with the 65 and 73 races of Colletotrichum lindemuthianum.
