Provided are methods for growing a plant under certain stressed conditions that alter the morphology of the plant. In certain aspects, however, although the plant is altered and may be undesirable for commercial purposed, the plant still produces an adequate number of seeds for breeding purposes. Further, because plants may be smaller in size, they can be grown at higher densities, allowing the production of large populations of plants to be brought under controlled conditions which can exclude pollinating insects and thus increase the genetic purity achievable in a breeding program.

The present invention discloses an “inferior-eliminating and superior-selecting” breeding method for synergistically improving wheat yield and quality. A method for breeding target wheat varieties with improved yield and quality is provided herein, which combines the advantages of pedigree method and hybrid method, and provides a method for selection of all generations using molecular marker in combination with phenotype identification, and for selection of each generation according to different standards. Different from the derivative system method, the method reserves the traceability of line history and genetic relationship and the characteristics of simple operation and abundant genetic diversity of the hybrid method. The parents have clear backgrounds before combination and the selection process is simple and easy to operate, with clear goal, especially for those with no breeding experiences, it is easy to master and provides technical support for the rapid breeding of new varieties of high-quality and high-yield wheat.

The present disclosure discloses a method for using plant heterosis. The method comprises the following steps: S1, transforming the meiosis of germ cells of hybrids into mitosis-like so as to obtain gametes whose genotype and chromosome ploidy are consistent with hybrids by using gene mutation or gene engineering technology; and S2, influencing and involving in the development of gametes or embryos in plants by using gene mutation and gene engineering technology, wherein a protein involved is MTL protein.

This disclosure concerns methods and compositions for identifying canola plants that have a low fiber content trait. Some embodiments concern a chromosomal interval and a quantitative trait locus associated with low fiber content in canola plants or germplasm. Some embodiments concern molecular markers to identify, select, and/or construct low fiber content canola plants and germplasm, or to identify and counter-select plants with relatively higher fiber content. This disclosure also concerns canola plants comprising a low fiber content trait that are generated by methods utilizing at least one marker described herein.

This invention relates to compositions and methods for modifying an endogenous nucleic acid encoding a Phytochrome A (PHYA) polypeptide for suppression of the shade avoidance response in plants. The invention further relates to plants produced using the methods and compositions of the invention.

The present invention relates to rice grain with thickened aleurone. Also provided is a rice plant comprising at least one genetic variation which reduces the activity of at least one ROS1a gene in the plant. Grain of the invention, or aleurone there-from, has improved nutritional properties, and hence is particularly useful for human and animal feed products.

The invention discloses proteins and biological materials related to rice (Oryza sativa L.) yield, and use thereof in increasing rice yield. The protein related to rice yield disclosed by the invention is OsDREB1C having SEQ ID NO: 1 in the Sequence Listing as its sequence, and having SEQ ID NO: 2 in the Sequence Listing as its coding gene sequence. Experiments have demonstrated that OsDREB1C and the associated biological materials thereof of the invention can enhance the photosynthetic efficiency of a plant, promote nitrogen uptake and transport and increase the nitrogen content in the plant and in its grains, promote earlier heading, and improve yield. The OsDREB1C and the associated biological materials thereof of the invention are of great biological significance and industrial value, and find bright prospects for application.

The invention relates to a Solanum lycopersicum plant comprising in its genome, on chromosome 1, introgressed sequences from Solanum habrochaites, wherein said introgressed sequences confer to the plant an improved phenotype corresponding to both an increased yield and an increased amount of soluble sugars allocated to fruits (Brix*Yield), with respect to a corresponding plant devoid of said sequences, and wherein said introgressed sequences are chosen from those present in the genome of a plant of the seeds ToPATYIELD NCIMB accession number 42567. The introgressed sequences are preferably characterized by defined alleles of different SNPs. on chromosome 1, inter alia allele T of SNP IL2_3605 (SEQ ID No. 9) and/or allele A of IL2_6411 (SEQ ID No. 12). The invention is also directed to parts of these plants with improved phenotype, as well as progeny, to the use of these plants for introgressing the improved phenotype in another genetic background, as well as to different methods for obtaining tomato plants or seeds with increased yield and brix*yield.

The present invention relates to day-length neutral Cannabis plants with one or more value phenotypes.
