I read about a line of seeds that germinate at different times to ensure a crop despite drought, but I can't find the name of the seed.
a study found that temperature is a primary factor affecting the morpho-physiological, developmental, and yield attributes of soybean¹. The study also found that soybeans exposed to warmer parental temperature (37°C/29°C) during pod filling significantly decreased the transgenerational seed germination when incubated at 18, 28, and 38°C¹. This suggests that the impact of temperature during soybean development is transferable and has transgenerational effects on seed germination ability¹.
Another study conducted a genome-wide association study of soybean seed germination under drought stress². This study examined the germinating seed drought-tolerance phenotypes and genotypes of a panel of 259 released Chinese soybean cultivars².
On average, the survival rate for a germinating soybean seed is 85%³. The seeding rate can be estimated by using both the germination percentage listed on the seed tag and the survival rate³.
These studies indicate that environmental factors like temperature and drought can affect the germination rates of soybean seeds. However, it's important to note that while there is ongoing research in this area, the development and commercial availability of genetically engineered soybean seeds that germinate at different rates may vary. It's always best to check with seed suppliers or agricultural extension services for the most current and applicable information.

Thanks. This was very helpful. The PRA was the source of the genetically engineered soybean, but I have yet to find a seed company that is marketing it.
