Patent number: 6662185Abstract: Methods and systems for assessing wide-area performance of a crop variety using a linear mixed model that incorporates geostatistical components and includes parameters for fixed effects, random effects and covariances. A wide-area database is constructed that includes covariate data, spatial coordinates of testing locations of one or more crop varieties, geographic areas in which the testing locations reside, and performance trait values of one or more crop varieties. The parameters for the fixed effects, random effects and covariances are estimated by fitting the linear mixed model with data in the wide-area database. Long-term expected performance of the crop variety may be estimated using the parameter estimates. Average performance of the crop variety for a given time period may be predicted using the parameter estimates.Type: GrantFiled: October 14, 2000Date of Patent: December 9, 2003Assignee: DeKalb Genetics CorporationInventors: Steven B.

Patent number: 6635806Abstract: Methods and compositions for the expression of transgenes in monocot plants including maize are disclosed. In the invention, gene silencing is avoided by use of monocot-homeologous sequences from plants of the genus Coix for transformation. Included in these transgene sequences are Coix promoters, enhancers, coding sequences and terminators. Suitable alternatives to maize-derived transgenes are desirable for expression in maize in that homology-based gene silencing can limit or effectively eliminate transgene expression.Type: GrantFiled: May 14, 1998Date of Patent: October 21, 2003Assignee: DeKalb Genetics CorporationInventors: Alan L.

Patent number: 6569648Abstract: The present invention provides a highly-efficient method for the selection and identification of insertional mutants. In the technique, a non-selective amplification is used to isolate a plurality of insertion events from a population of individuals comprising insertion mutations. Specific insertion events can then be identified from the population by the use of gene specific probes or primers. Through the identification of mutants for a particular gene, data may be obtained regarding the function and phenotypic effects of that gene, and thereby, the gene can be employed in the creation of novel biotechnological products.Type: GrantFiled: July 20, 1999Date of Patent: May 27, 2003Assignees: DeKalb Genetics Corporation, Yale UniversityInventors: Stephen L.
