実験手順

T2 plants of events EAFS 4818.1.5 and EAFS 4871.6.10 that were homozygous for an YL DGAT1/YL DGAT2 event (Example 6) and a PGM/RFO ko event (Example 31), respectively were crossed. Resulting F1 seed were analyzed by GC and TLC as described above to monitor presence of the DGAT trait (elevated oleic acid) and PGM/RFO ko trait (reduced raffinose and stachyose). A total of 23 F1 seed with elevated oleic acid content and reduced raffinosaccharide levels were planted, resulting plants were grown to maturity. For every F1 plant a total of 48 F2 seed were subjected to the following analysis sequence. Seed oil content was measured non-destructively by NMR (Example 4). Seed were chipped and the resulting seed chip was extracted with heptane. Heptane extracts were subjected to GC analysis to determine the presence of the DGAT transgene (indicated by the altered fatty acid profile of the oil). The heptane-extracted residue was subjected to TLC analysis of raffinose and stachyose content (Example 29) to determine presence or absence of the EAFS 4871.6.10 transgene. In this manner 1104 seed were genotyped and the effect of transgene genotype on oil content was determined.
