Patent number: 5981832Abstract: This invention relates to a method for improving the efficacy of a plant breeding program which has as its goal to selectively alter phenotypic traits that are capable of being described numerically and are under the control of quantitative trait loci (QTLs). The method combines the newer techniques of molecular biology with modifications of classical pedigree breeding strategies. Progeny performance is predicted on the basis of at least one secondary trait, facilitating selection strategies. In particular, regression estimates are obtained by determining the relationship between selected inherited marker loci and quantitative phenotypic trait values in predictor populations, and used in combination with inherited marker profiles of plants, to implement a selection strategy in related populations.Type: GrantFiled: May 23, 1995Date of Patent: November 9, 1999Assignee: Dekalb Genetics Corp.Inventor: Richard Johnson

Patent number: 5665582Abstract: A method for the isolation and sorting of biological materials has been developed. Biological material includes chromosomes, segments of chromosomes, cell organelles, or other minute cellular components. The biological material is separated from the cellular milieu, if necessary, and anchored to a support. Examples of a support are glass coverslips, glass or polymer beads. The anchoring is by means of a reversible polymer and cross-linking system. The supported biological material may then be labelled with compositions capable of binding to said material, and with magnetic particles. Examples of the binding material include nucleic acid probes and antibodies. An example of the antibodies would be those directed to histones. Other labels, for example, fluorescein-biotin-avidin may be used. The material may be released from the support and sorted by a magnetic force.Type: GrantFiled: April 18, 1994Date of Patent: September 9, 1997Assignee: Dekalb Genetics Corp.Inventors: Albert P.

Patent number: 5436389Abstract: This invention relates generally to the production of maize, commonly known in the United States as corn, and more specifically to hybrid corn plants with certain advantageous phenotypes resulting from interactions of the haploid genetic contributions of inbred parental lines. This invention relates to the hybrid genetic complement, the expression of which produces these phenotypes and to the complement as housed in seeds and tissues, in particular, those capable of producing or regenerating the hybrid plants either in vivo or in vitro. An aspect of this invention, hybrid DK570, is characterized by many advantageous phenotypic traits including superior yield and standability, i.e. root lodging. It has characteristic restriction fragment length polymorphism (RFLP) and isozyme profiles.Type: GrantFiled: December 7, 1993Date of Patent: July 25, 1995Assignee: DeKalb Genetics Corp.Inventor: John H.
