100-seed weight
In three years, GM soybeans had higher 100-seed weights than wild and hybrid soybeans. The F1 hybrid 100-seed weight was more similar to that of wild soybean, no differences were recorded for 100-seed weight between the F1 hybrid and wild soybean, however, both F2 and F3 hybrids had higher 100-seed weights than their wild soybean counterparts; no parameters significantly differed among RR, RS, and SS in the F2 or F3 population.
