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..

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

GENETIC VARIABILITY OF \u3ci\u3eColletotrichum lindemuthianum\u3c/i\u3e BY SEQUENCING ITS REGIONS

INTRODUCTION Anthracnose, caused by Colletotrichum lindemuthianum, is one of the most important diseases of the common bean (Phaseolus vulgaris L.) in Brazil and in other regions of the world (Pastor-Corrales et al. 1994). Anthracnose occurs more severely in places where relative humidity conditions above 91% and temperatures ranging from 18° and 22°C predominate (Kelly et al. 1994). High genetic variability of C. lindemuthianum has been described worldwide, and more than 247 different races of the pathogen have been identified, which 35 occur exclusively in Brazil (Nunes et al. 2013). The high number of physiological races and the complexity in the use of genetic resistance of the C. lindemuthianum fungus are evidence of wide virulence diversity (Pastor-Corrales et al. 1994). Therefore, the objective of this work was to characterize isolates of C. lindemuthianum from Pernambuco state of Brazil through sequencing of ITS regions

Characterization of the anthracnose resistance gene present in the Andean cultivar Perla

Biotic stress is a major cause of yield losses in common bean production worldwide. Anthracnose (ANT), caused by the fungus Colletotrichum lindemuthianum (Sacc & Magnus) Briosi & Cavara is among the diseases that affect beans and can cause yield losses of up to 100%, especially when environmental conditions are favorable for the development of the disease (Singh and Schwartz, 2010). The use of disease resistance genes is the most economical and ecological strategy for disease control. Finding and characterization of ANT resistance genes in different materials and available cultivars is important (Mahuku and Riascos, 2004). To date different anthracnose resistance genes were identified in common bean, most of them in Mesoamerican germplasm. Thus, characterization of new Andean sources of resistance is important for bean breeding. In the present work the resistance gene present in the Andean cultivar Perla was studied.Fil: Taboada, Gisel María. Instituto Nacional de Tecnología Agropecuaria. Centro Regional Salta.

Genetic analysis of anthracnose resistance in Jalo Pintado 2 dry bean cultivar

Anthracnose, caused by the fungus Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi and Cavara, is one of the most widespread and economically important diseases of common bean (Phaseolus vulgaris L.) worldwide (Pastor-Corrales and Tu, 1989). Search for new sources of resistance have been the objective of many breeding programs, since genetic resistance is the most effective and environmentally friendly management strategy for the control of anthracnose disease in common bean. Therefore, this study aimed to investigate the genetic resistance to anthracnose in the Andean cultivar Jalo Pintado 2.Fil: Frias, A. A. T.. Universidade Estadual de Maringá; BrasilFil: Castro, S. A.
