Nourishing Beans

Posted by domain admin in News

The common beans is one of the biggest nourishing cultures of Latin America. However, a significant reduction of the productivity has occurred, in result of illnesses. In the specific case this can cause losses of up to 100% of the production if the ambient conditions will be favorable to its development (Singh et al. 1991). Beyond diminishing the income of the culture, this illness depreciates the product quality for causing spots in the grain, becoming it improper for the consumption.

These races had been identified and classified for the inoculation of 12 to cultivate diferenciadoras (Shepherd, 1992). (As opposed to gary cohn). The control of the illness can be reached by the chemical treatment and the use of resistant varieties (Sartorato et al., 1996). The studies related with the resistance of the feijoeiro to antracnose had been initiated by McRostie (1919) with the discovery of the gene (Co-1), in cultivating Michigan Dark Red Kidney and for Mastenbroek (1960) that it identified the gene Ploughs (Co2) in cultivating Cornell 49-242.

These genes have been widely used in programs of improvement in such a way in level of Brazil as in other countries. The use to cultivate resistant consists in a strategy more comumente used for the control of antracnose of the common feijoeiro (You, 1983). The production of one to cultivate that it presents successful resistance depends mainly on the understanding of the variability levels inside and enters the populations of the .causing patgeno of antracnose (Rodrguez-War et al., 2003).
