Soybeans having high germination rates and ultra-low raffinose and stachyose content

摘要

Soybean seeds having an ultra-low raffinose and stachyose phenotype. Also disclosed is a mutant allele of soybean designated SG-ULRFO which results in an ultra-low raffinose and stachyose phenotype. The present invention also relates to a soybean seed, a soybean plant and parts of a soybean plant and a soybean hybrid which comprises the mutant allele. Also disclosed are ultra-low raffinose and stachyose soybean seeds having unexpectedly increased germination rates when compared with soybean lines not having a low raffinose and stachyose seed content. Also disclosed are mutant RS3 and RS4 genes with polymorphisms which contribute to the ultra-low raffinose and stachyose phenotype as described in the present invention. The present invention also relates for method of using the soybean seeds and plants of the present invention, to plants parts derived from the present invention, to methods of producing transgenic plants using the plants and seeds of the present invention.
