The present disclosure relates to the technical field of breeding, in particular to an environmental-friendly and efficient breeding method of high-yield and high-quality wheat cultivars. In the present disclosure, the breeding method can improve a breeding efficiency of excellent new cultivars, further realize large-scale production, and further increase a planting area of the excellent cultivars. In addition, the breeding method can increase the number of products for the new cultivars, further increase a diversity of early-generation materials, and further increase a diversity of hybrid samples through the innovation of hybridization and breeding methods. The environmental-friendly and efficient breeding method of high-yield and high-quality wheat cultivars can increase a richness of excellent characteristics of the new cultivars through high-generation materials, hybridization, and off-site identification, thereby further improving an effect of breeding.

The avirulent strain A257 of the bacterial rice pathogen Burkholderia glumae is an effective priming material to reduce or suppress major diseases in rice and other plants. Protection includes that against bacterial panicle blight, sheath blight, and narrow brown leaf spot. A mutant derivative of A257, A257qsmR, significantly reduces the risk that the priming agent might potentially revert to wild-type pathogenicity.

The disclosure relates to improving plant breeding methods by controlling for microbial diversity present in the plant breeding process.

Present invention teaches the method of using a keratin hydrolysis peptide (KHP) solution to enhance sweetness and flavors of tea leaves. By selectively choosing specific weights of feathers and water, and treating the mixture to a high-temperature high-pressure hydrolysis process, the resulting solution is confirmed to contain at least 253 peptides and then applied to the surface of tea leaves during sprouting stage and infused to the soil around the tea trees/plants; the increased content of L-theanine and polyphenol is separately tested and confirmed. Optionally, the KHP solution can be diluted by water, as taught in the specification, before applying to the tea leaves and the soil as taught herein.

Present invention teaches the method of using a keratin hydrolysis peptide (KHP) solution to enhance the drought-tolerance of the cotton plant. By selectively choosing specific weights of feathers and water, and treating the mixture, though one embodiment does not have water mixed in, to a high-temperature high-pressure hydrolysis process, the resulting solution is confirmed to contain at least 253 peptides and then applied to the cotton seeds and the soil around the cotton plants. Optionally, the KHP solution can be diluted by water, as taught in the specification, before applying to the seeds and the soil as taught herein.

The invention relates to methods and compositions for identifying soybean plants that are tolerant, have improved tolerance or are susceptible to Charcoal Rot Drought Complex. The methods use molecular genetic markers to identify, select and/or construct tolerant plants or identify and counter-select susceptible plants. Soybean plants that display tolerance or improved tolerance to Charcoal Rot Drought Complex that are generated by the methods of the invention are also a feature of the invention. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The present invention relates to a QTL allele in maize associated with drought resistance and carbon isotope composition as well as specific marker alleles associated with the QTL allele. The present invention further relates methods for identifying maize plants based on screening for the presence of the QTL allele or marker alleles. The invention also relates to methods for modifying drought resistance and carbon isotope composition in maize plants.

The present invention relates to methods and compositions for identifying, selecting and/or producing a plant or germplasm having root increased drought tolerance and/or increased yield under non-drought conditions as compared to a control plant. A maize plant, part thereof and/or germplasm, including any progeny and/or seeds derived from a maize plant or germplasm identified, selected and/or produced by any of the methods of the present invention is also provided.

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.
