Abstract: Considerable success has been obtained in the use of classical breeding to control economically important plant diseases, such as the coffee leaf rust and the coffee berry disease (CBD). There is a strong consensus that growing genetically resistant varieties is the most appropriate cost effective means of managing plant diseases and is one of the key components of crop improvement. It has also been recognized that a better knowledge of both, the pathogens and the plant defence mechanisms will allow the develo… Show more

“…It possesses the complete resistance factors proceeding from C. canephora, and has the same number of chromosomes as C. arabica, making crosses with this species possible. Before experiencing the disease, coffee-producing countries relied on the aid of CIFC, in Portugal, to develop resistant varieties based on HDT (Silva et al 2006). Several countries through their national research centres have cooperated with CIFC for the development of local adapted coffee cultivars displaying rust resistance (Bettencourt 1981(Bettencourt , 1983Rodrigues Jr et al 2000).…”

“…Warming temperatures at higher altitudes and the resulting shifts in moisture accumulation are likely allowing the rust to thrive in areas previously uninhabitable (Avelino et al 2006). Despite the availability of effective fungicides and resistant varieties for the control of CLR, it may still cause losses varying between 10 and 40% in different countries (Silva et al, 2006) because fungicides can be detrimental to the environment and are limited in capacity to combat coffee rust and some improved commercial varieties gradually losing their resistance to leaf rust in some countries, due to the appearance of new virulent races (Rodrigues et al, 2000).…”

“…There have been several attempts to model the spread of CBD and to identify efficient control strategies [10], [11], [13], [17], [18], [19], [20], [21], [28]. Possible control methods include genetic methods [3], [4], [5], [15], [27], biological control [12], chemical control [5], [22], [24] and cultivational practices [5], [19], [20], [21], [28]. Chemical methods appear to be the most effective, but present ecological risks.…”
