Conteúdo: |
Soybean rust, a foliar disease caused by Phakopsora pachyrhizi, is widely disseminated in the soybean production areas in many countries, including Brazil. The disease can cause severe losses, according to the conditions for pathogen's development. At the moment, no genotypes have been identified among commercial cultivars with satisfactory resistance. The objective of this work was to evaluate the rust resistant level of soybean lines from the breeding program of a cooperative project among Embrapa Soybean, EPAMIG and Triangle Foundation. The lines belong to the various maturing groups, varying from 110 to 137 days to reach complete maturation. The lines, sowed in plastic pots under greenhouse conditions, were inoculated fifteen days after the sowing date with a suspension of 3 x 105 spores / mL, using a manual sprayer. Ten days after inoculation, it was evaluated to resistance level, using a scale of one to five (1= 1% to 10%, 2= 11% to 25%, 3= 26% to 50%, 4= 51% to 75% and 5 > 75%). Two lines, MG/BR99-4611 (medium mature group) and MG/BR99-3313 (late mature group) showed satisfactory resistance to soybean rust. They can be readily useful to the farmers or be available for the breeding program. |
