CEREAL CROP SEED PRODUCTION

This invention describes a new method to generate cereal crop seed. The process involves the delivery of pollen of the male parent at will, as available either in a preserved pollen bank, or using real-time collection from male plants as they become available. Desired pollen is delivered to fertile females during the period when viable pollen from the females and locally proximal unrelated plants is not being released. The delivered male pollen is in such amounts and fortuitously timed that it preferentially pollinates the females. Such fortuitous timing may involve the intentional application of pollen to females a day or two prior to female parent pollen becoming viable, and/or during several periods wherein female parent pollen and/or other proximal plant pollen is not being shed.

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.

ANTHRANILATE SYNTHASE ALLELE FRAGMENTS FOR INCREASING RICE YIELD AND USES THEREOF
20190367973 · 2019-12-05 ·

Anthranilate synthase allele fragments for increasing rice yields and uses thereof. A method of differentiating rice materials with a superior allele associated with high yield includes: (1) detecting a genotype of rice to be detected based on a specific gene fragment; where the specific gene fragmentOsASA1 is located in rice genome, and there are typically two allelic forms of OsASA1, OsASA1_a shown as SEQ ID NO. 1 and OsASA1_b shown as SEQ ID NO. 2; and (2) determining and comparing the average yield of a rice population with a genotype of homozygous OsASA1_b and that of a rice population with a genotype of homozygous OsASA1_a under the same growth conditions in different geographical regions. The rice population with the genotype of homozygous OsASA1_b shows a higher average yield than the rice population with the genotype of homozygous OsASA1_a.

Rice plants with altered seed phenotype and quality

The invention relates to plants with an improved organ phenotype. In particular, the invention relates to rice plants which have better grain quality and altered seed phenotype due to increased expression of GW7 (LOC_Os07g41200) or due to a combination of increased expression of GW7 and reduced expression of GS3 (OsSPL16). Grains show increased length and increased slenderness.

The invention further relates to methods for producing a rice plant containing in its genetic material one or more transgenes and to the transgenic rice plants and plant parts produced by those methods. This invention also relates to rice cultivars or breeding cultivars and plant parts derived from rice cultivar Calhikari-203, to methods for producing other rice cultivars, lines or plant parts derived from rice cultivar Calhikari-203 and to the rice plants, varieties, and their parts derived from the use of those methods. The invention further relates to hybrid rice seeds and plants produced by crossing the cultivar Calhikari-203 with another rice cultivar.

A rice cultivar designated ARoma 22 is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar ARoma 22. Further, it provides methods for producing a rice plant by crossing ARoma 22 with itself or another rice variety. The invention also encompasses any rice seeds, plants, and plant parts produced by the methods disclosed herein, including those in which additional traits have been transferred into ARoma 22 through the introduction of a transgene or by breeding ARoma 22 with another rice cultivar.

Grain production

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, 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 optionally, avoids or enhances self-pollination or pollination from neighboring 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. The intentional delivery of self- or sib-pollen results in a decrease in contamination from undesirable outcrossing.

Unnatural plant showing induced gene expression and method for producing same

A problem to be solved by the present invention is to provide a non-natural plant in which expression of a gene of interest is induced and a method for producing the same. Particularly, the present invention relates to a non-natural plant in which the expression of the gene is stably induced even in the absence of a physical or chemical stimulus inducing the expression of the gene, and a method for producing the same. When the induction of the expression of the gene enhances a trait of a plant of interest, the present invention provides a non-natural plant in which the trait is enhanced and a method for producing the same. To solve the problem, a non-natural regenerated plant in which the expression of the gene is induced can be produced by forming a callus from a portion of the plant of interest and then subjecting the callus to a treatment by which the expression of the gene is induced.
