GRAIN PRODUCTION WITH MALE-STERILE FEMALE PLANTS

This invention describes a new method to increase grain yields in any crop plant by modifying pollination to effect an increase in grain yield, a change in grain content or characteristics, a decrease in contamination, or a combination of these attributes. The process involves the intentional delivery of pollen of the male plant at will to designated male-sterile female plants as available either in a preserved pollen bank, or real-time collection from male plants as they become available, in a growth chamber for example. Desired pollen is delivered to fertile females. The delivered pollen.sup.M is in such amounts and fortuitously timed that it preferentially pollinates the females and pollination from neighboring male-fertile plants. The intentional delivery of genetically different pollen will result in increased heterosis and accompanying grain yield increases resulting from increased grain size and the potential to influence grain content and constituents. The invention also permits real-time agronomic decision making in order to maximize grain yield by overcoming biotic and abiotic challenges in the growing season which may or may not have been anticipated.

RESTORER PLANTS

Hybrid cereals are described which are obtained by restoring the pollen fertility for the Pampa cytoplasmic male sterility (P-CMS) and which are characterized by a reduced linkage drag. Plants are provided, in particular rye, which, as the male pollen parent, are capable of restoring the pollen fertility for the P-CMS. Furthermore, the nucleic acid molecule which carries the necessary information for restoring the P-CMS, DNA and vectors which contain such a nucleic acid molecule, corresponding host cells as well as a protein which can be encoded by the nucleic acid molecule and antibodies directed against it are also described. Furthermore, methods for the production of corresponding hybrid plants and transgenic plants are provided.

Wheat stripe rust resistance genes and methods of use

Compositions and methods for enhancing the resistance of wheat and barley plants to wheat stripe rust caused by Puccinia striiformis f. sp. tritici are provided. The compositions comprise nucleic acid molecules encoding resistance (R) gene products and variants thereof and plants, seeds, and plant cells comprising such nucleic acid molecules. The methods for enhancing the resistance of wheat and barley plants to wheat stripe rust comprise introducing a nucleic acid molecule encoding an R gene product into a wheat or barley plant cell. Additionally provided are methods for using the wheat and barley plants in agriculture to limit wheat stripe rust.

Market-driven pollen selection

This invention describes a new method of grain production wherein designated male plant pollen may be selected at anytime before pollination of a designated female plant. In the method, a designated female plant having both female and male components is grown. Furthermore, designated male pollen is selected for use in cross-pollinating the designated female plant. Cross-pollination may occur on one more days, is intentional, and occurs at a time when male components are not shedding pollen. The criteria used for selecting designated male pollen may include, but is not limited to, market information and commodity price information. Moreover, the designated male plant pollen may have a different maturity period compared to the designated female, selection may occur after the female has germinated, and/or result in a higher harvested crop value than other available pollen. Accordingly, the process involves the intentional delivery of designated male plant pollen at will, as available either in a preserved pollen bank or real-time collection from male plants as they become available, in a growth chamber for example. The delivered designated male plant pollen is in such amounts and fortuitously timed that it preferentially cross-pollinates the designated female plant. The invention also permits real-time agronomic decision making to influence grain content and constituents to maximize grain value.
