Soybean Cultivar S100319 Transgenic Trait Introgression

The patent applies preliminary action by pre-introducing transgenic traits (such as herbicide resistance and disease resistance genes) into the soybean cultivar before traditional breeding begins. This allows the desired traits to be established in advance through genetic transformation, eliminating the need for lengthy traditional breeding cycles to achieve the same result. The cultivar S100319 was developed using this approach, combining multiple desirable traits in a single transformation event or through targeted gene introgression.

The patent replaces the mechanical system of traditional physical crossing and selection with genetic engineering techniques. Instead of manually crossing plants and selecting offspring over multiple generations, the invention uses molecular biology methods (such as Agrobacterium-mediated transformation or gene editing) to directly introduce and combine desired traits at the DNA level. This substitution dramatically increases breeding efficiency while achieving the same adaptability and trait combination goals.

The patent applies parameter changes by modifying the genetic parameters of the soybean cultivar through direct genetic transformation rather than through multiple generations of crossing. By changing the genetic composition at the molecular level (introducing specific genes or gene sequences), the desired agronomic qualities are achieved in a single step or few steps, rather than requiring complex multi-generational breeding programs. This reduces process complexity while maintaining the reliability of the resulting cultivar.
