dc.descriptionA total of 452 sugarcane clones were tested for their reaction to rust by field evaluation. These included introduced, locally-developed commercial and breeding varieties, the original clones of Saccharum species, and the S. spontaneum hybrids of F1, BC1, and BC2 generations. The inheritance trends of susceptibility to rust were also studied. It was found that nearly 54% of the clones tested were infected by the rust, and 15% were either susceptible or highly susceptible. In the genus Saccharum, most of S. officinarum clones were infected with the rust although the infection in most cases was mild. A clear inheritance trend of rust susceptibility was established from percent infection values of the original seedlings. These values were obtained from crosses with parental varieties having known reactions to the disease. In addition to variety, other factors affecting the incidence of the disease are discussed.en-US
dc.descriptionUn total de 452 clones de caña de azúcar se probaron en el campo para evaluar la reacción a la roya. Se usaron variedades comerciales desarrolladas en nuestro programa de mejoramiento, clones originales de la especie Saccharum e híbridos de S. spontaneum de las generaciones F1, BC1, y BC2. Se hizo un estudio de la tendencia hereditaria de la susceptibilidad a la roya. El 54% de los clones estudiados estaban infectados con la enfermedad; 15% se evaluaron como susceptibles o muy susceptibles. Se presume que la principal fuente de susceptibilidad a la roya en el género Saccharum es S. officinarum. La tendencia hereditaria a la susceptibilidad a la roya se estableció mediante el porcentaje de infección que mostraron los seedlings originales. Cruces de las variedades progenitoras cuya reacción a la enfermedad ya se conoce, sirvieron de base para fijar estos valores. Se examinaron otros factores que influyen en la incidencia de la enfermedad.es-ES
