Pod number per plant
The pod number per plant of wild soybean and F1 hybrids
was significantly higher than that of GM soybean in 2018. Wild soybean
produced 565 pods per plant, while F1 hybrids produced
353 pods, and a significant difference was observed in the wild soybean
and F1 hybrid groups (Table 3).
F2 homozygous resistant, heterozygous and homozygous
susceptible plants produced 561, 545, and 686 pods per plant,
respectively, and no significant differences were found between RR, RS
and SS. Analysis of variance also showed that the pod numbers were not
significantly different between wild soybean and F2hybrids (Table 3).
Pod numbers were compared between different genotypes of the
F3 population, and no significant of the parameters
differed among RR, RS, and SS. The pod number of the F3hybrids was also intermediate between that of wild and GM soybeans and
was more similar to that of the wild soybean. In addition, both
F3 hybrid and wild soybean pod numbers were much higher
than those of GM soybeans.
