Rice is described that is tolerant/resistant to AHAS/ALS inhibitors because of a plurality of mutations that act synergistically in providing resistance/tolerance to the herbicide. Tolerance/resistance is due to presence of combined mutations in the rice leading to amino acid substitutions (A205V and G654E) in the AHAS/ALS enzyme. Use of the rice for weed control and methods of producing tolerant/resistant rice are also disclosed.

Plants, seeds and tissue cultures of the hybrid rice HR170003, and methods for producing a rice plant by crossing a rice plant of hybrid rice HR170003 with itself or with another rice plant, such as a plant of another rice variety or rice hybrid, are disclosed.

Plants, seeds and tissue cultures of the hybrid rice HR170002, and methods for producing a rice plant by crossing a rice plant of hybrid rice HR170002 with itself or with another rice plant, such as a plant of another rice variety or rice hybrid, are disclosed.

The present invention relates to plants having resistance to the herbicide oxyfluorfen conferred by a loss of function of one or more sulfolipid biosynthesis enzymes involved in the sulfolipid biosynthesis pathway and methods of producing said plants. The present invention is further directed toward rice lines having non-transgenic resistance to the herbicide oxyfluorfen conferred by mutant allele ROXY. The invention also relates to methods for producing a rice plant containing mutant allele ROXY containing in its genetic material one or more transgenes and to the transgenic plants produced by those methods. This invention also relates to rice cultivars or breeding cultivars and plant parts derived from rice plants containing mutant allele ROXY and to methods for producing other rice cultivars, lines or plant parts derived from rice plants containing mutant allele ROXY. The invention further relates to transferring mutant allele ROXY to different genetic backgrounds.

The present disclosure relates to a method for improving a plant variety. The present disclosure relates to a method of plant breeding, the method comprising the following steps: 1) Selecting a background variety and a donor variety, 2) Comparing the background variety and the donor variety to identify a module or locus to be improved, 3) Crossing the background variety and the donor variety to obtain a hybrid progeny, backcrossing the hybrid progeny to the background variety to obtain a backcross progeny, and constructing a genetic population using the backcross progeny, 4) Selecting, using molecular markers or a sequencing method, a backcross progeny having chromosomal regions derived from the background variety except for the module or locus to be improved, the molecular markers comprising genome molecular markers and module or locus molecular markers designed according to the selected module or locus, 5) Self-crossing the selected backcross progeny to obtain an improved plant variety.

The present disclosure also relates to a plant variety obtainable by said method.

The method can select a plant in laboratory, obtaining a plant with a definite and improved trait and gene with high breeding efficiency, and achieving division of labour during the breeding process and accumulation of breeding advantages.

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 via automatic or semi-automatic means, 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 avoids 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 semi-dwarf, mid-season, medium grain rice variety MM17 is disclosed. The invention relates to the seeds and plants of the semi-dwarf, mid-season, medium grain rice variety MM17. The invention also relates to methods for producing a rice plant produced by crossing the semi-dwarf, mid-season, medium grain rice variety MM17 with itself or another variety.

This invention describes a new method to generate oilseed 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.

The inbred rice line designated DG263L is disclosed. Embodiments include the seeds of inbred rice line designated DG263L, the plants of inbred rice line designated DG263L, plant parts of inbred rice line designated DG263L, and methods for producing a rice plant produced by crossing rice DG263L with itself or with another rice variety. Embodiments include methods for producing a rice plant containing in its genetic material one or more genes or transgenes and the transgenic rice plants and plant parts produced by those methods. Embodiments also relate to rice cultivars, breeding cultivars, plant parts, and cells derived from inbred rice line designated DG263L, methods for producing other rice cultivars, lines or plant parts derived from inbred rice line designated DG263L, and the rice plants, varieties, and their parts derived from use of those methods. Embodiments further include hybrid rice seeds, plants, and plant parts produced by crossing DG263L with another rice cultivar.
