Research Project: Field Evaluation of Soybean Lines for Resistance to Soybean Aphid

Location: North Central Agricultural Research Laboratory

2012 Annual Report


1a.Objectives (from AD-416):
Advance soybean lines with field resistance to soybean aphid within the South Dakota State University soybean breeding program by crossing with contemporary soybean lines and re-evaluate resistance in crosses.


1b.Approach (from AD-416):
A total of 330 early maturity soybean lines will be scored for resistance to soybean aphid infestation. The lines will be planted annually each in 3-ft long rows in a plot at the Eastern South Soil & Water Research Farm, replicated three times, and scored in August each year.


3.Progress Report:

A total of 348 early maturity soybean lines were planted at the Eastern South Soil & Water Research Farm near Brookings, SD in a three-replicate block. Nearly all of the 348 lines germinated and reached the early reproductive stages of development. They are awaiting evaluation in August 2012 with regard to resistance against soybean aphid infestation.
