Quantitative Trait Loci Associated with Foliar Trigonelline Accumulation in Glycine Max L.

The objective of this study was to utilize a Glycine max RIL population to (1) evaluate foliar trigonelline (TRG) content in field-grown soybean, (2) determine the heritability of TRG accumulation, and (3) identify DNA markers linked to quantitative trait loci (QTLs) conditioning variation in TRG accumulation. Frequency distributions of 70 recombinant inbred lines showed statistically no significant departure from normality (P >.05) for TRG accumulation measured at pod development stage (R4).
