The present invention relates to novel Samkwang (SA)-flo3, a mutant line derived from Samkwang with floury endosperm, and a use thereof. More specifically, the present invention includes Samkwang (SA)-flo3 with floury endosperm suitable for exclusive production of dry-milled rice flour and relates to a method for breeding the rice cultivar, a composition, a kit, a method for determining floury endosperm characteristics of rice in the next generation of the rice cultivar, and a food composition comprising the rice cultivar, seeds thereof or extracts thereof as an active ingredient.

The Samkwang (SA)-flo3 provided by the present invention has floury endosperm characteristics and is a mutant line similar in agricultural characteristics to the original cultivar Samkwang and thus can be advantageously utilized as a novel material for various rice processed foods due to its high dry milling efficiency.

A rice cultivar designated Ozark is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar Ozark. Further, it provides methods for producing a rice plant by crossing Ozark 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 Ozark through the introduction of a transgene or by breeding Ozark with another rice cultivar.

The invention relates to methods of increasing plant yield, and in particular grain or seed number by introducing at least one mutation into at least one UPL2 gene. Also described are genetically altered plants characterised by the above phenotype.

A method of enhancing grain yield of a Gramineae plant is provided. The method comprises: (a) crossing a recipient plant with a donor plant comprising a sequence variation in a TPR allele, said sequence variation imparting enhanced grain yield; and (b) selecting a progeny plant of said crossing comprising said sequence variation by identifying said variation, said progeny plant being characterized by an improved grain yield relative to said recipient plant. Also provided are plants and processed products resultant of the method.

A rice white leaf and panicle gene wlp3 is provided. The cDNA sequence of the white leaf and panicle gene wlp3 is shown in SEQ ID NO: 1, and the encoded amino acid sequence of the protein is shown in SEQ ID NO: 2. The rice white leaf and panicle gene wlp3 is applied to rice stress resistance and yield increase. The white leaf and panicle gene wlp3 is configured to improve cold tolerance of plants, enhance photosynthetic rate, increase plant height, leaf albinism at seedling stage, panicle albinism at heading stage, and increase panicle length at low temperature. The present disclosure obtains the rice white leaf and panicle gene wlp3 through screening and mutagenesis, which is related to the stress resistance and chlorophyll synthesis of rice. Therefore, the present disclosure provides a foundation for rice breeding.

The herbicide-tolerant rice cultivar designated CLL19 and its hybrids and derivatives are disclosed.

A rice cultivar designated CLM05 is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar CLM05. Further, it provides methods for producing a rice plant by crossing CLM05 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 CLM05 through the introduction of a transgene or by breeding CLM05 with another rice cultivar.

The herbicide-tolerant rice cultivar designated CLL19 and its hybrids and derivatives are disclosed.

Plants, seeds and tissue cultures of the long grain aromatic rice cultivar RT22J502, and methods for producing a rice plant by crossing a rice plant of rice cultivar RT22J502 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 RT23M402, and methods for producing a rice plant by crossing a rice plant of hybrid rice RT23M402 with itself or with another rice plant, such as a plant of another rice variety or rice hybrid, are disclosed.
