DECATUR, Ill. (DTN) -- Talk about a chip off the old block. Plant breeders at Monsanto are using seed chipping to speed up genetic discovery.
Each of the 600-plus kernels on an ear of corn is unique. The DNA in each has its own genetic makeup, and each could grow into a mature plant unlike any other.
In the past, plant breeders manually punched a small hole in plant leaves to obtain samples. Today, a machine called "the seed chipper" shaves a tiny tissue sample from each seed -- avoiding the germ so the seed remains viable.
Scientists use the ...
