Co-segregation of recombinant inbred lines of the common bean to races 65 and 73 Colletotrichum lindemuthianum.

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 × Rudá cross with the 65 and 73 races of Colletotrichum lindemuthianum

Fine mapping of anthracnose resistance allele Co-14 in the common bean cultivar and 277.

The objectives of this study were to fine-map the anthracnose-resistance locus in AND 277 and to identify DNA markers tightly linked to the Co-14 allele, previously mapped on Pv01

Inheritance and allelic relationships of anthracnose resistance in common bean paloma cultivar

Anthracnose, caused by Colletotrichum lindemuthianum L., is one of the most important fungal diseases of common bean (Phaseolus vulgaris, L). Genetic resistance is the most effective method for this disease control. So far, twenty one resistance genes have been already characterized, and among them, only eight are Andean and due to it, the search for Andean resistance sources is really necessary. This way, the work aimed to characterize the genetic resistance of an Andean common bean cultivar.Fil: Castro, S. A. L.. Universidade Estadual de Maringá; BrasilFil: Gonçalves Vidigal, M. C..
