characteristics (Lambert and Tyler, 1999). The lack of development of superior SIR cultivars may be due to There has been limited success over the past 30 yr in the developthe quantitative nature of resistance and to the retention ment of superior soybean cultivars [Glycine max (L.) Merr] with of undesirable PI donor alleles affecting any number insect resistance. Success may be hampered by the quantitative nature of resistance and by linkage drag from resistant plant introduction of traits because of their tight linkage with the insect (PI) donor parents. Soybean insect resistance quantitative trait loci resistance alleles, or QTL. This condition is often associ-(SIR QTLs) have been identified from PI 229358 and PI 171451 ated with the use of nondomesticated germplasm for the by restriction fragment length polymorphism (RFLP) analysis. The introgression of novel alleles and is generally referred to objective of this study was to tag the SIR QTLs from PI 229358 with J.M. Narvel,
