Aiming to evaluate the reaction of soybean lines to the attack of the complex of stink bugs, 67 genotypes, divided in three experiments by cycle (early, medium and late) were investigated. Due to the higher number of lines, the early genotypes group was divided into two experiments. Plots consisted of 4 rows of 4m of soybean each one. For evaluation the stink bugs population (medium and large size nymphs from 3rd - 5th instar and adults), soybean yield, seed quality and agronomic treats. Insect population sampling started when soybeans reached the R1 growing stage, by using the beat cloth method, with four samples per plot taken once a week. When the population approached the decision levels, the frequency was increased to two samples/week. When the stink bug population reached 8 insects/sample (twice the presently recommended economic damage level), an application o endosulfan at 525g ai/ha was performed. At the end of the cycle two meters of the two central rows of each plot were harvested for evaluation. No lines with simultaneous high productivity and high seed quality were observed. The breeding lines BRQ 93-357, BRT 91-14888 and BRT 91-13431 showed improved seed quality and reduced stink bugs population, thus requiring less insecticide application, and were recommended for backcross to improve agronomic treats. |
