The invention belongs to the technical field of crop cultivation, and particularly relates to a rice aroma-enhancing and yield-increasing agent and application thereof, and the rice aroma-enhancing and yield-increasing agent comprises a primary aroma-enhancing and yield-increasing agent and a secondary aroma-enhancing and yield-increasing agent; the primary aroma and yield increasing agent is jasmonic acid methyl ester with the concentration of 50 [mu] mol / L-100 [mu] mol / L; the formula of the secondary aroma-enhancing and yield-increasing agent is as follows: each liter of the secondary aroma-enhancing and yield-increasing agent contains 0.8 to 1.2 g of ornithine, 25 to 35 mmol of trehalose, 1.0 to 1.4 g of vitamin B1, 1.8 to 2.2 g of vitamin B5, 1 to 3 mg of nano zinc oxide, 4 to 6 mg of sodium selenite, 1 to 3 g of KH2PO4 and the balance of water. The rice aroma-enhancing and yield-increasing agent disclosed by the invention has excellent performance when being applied to three aromatic rice varieties, the 2-AP content is remarkably increased, the yield is kept stable and even slightly increased, and the contradiction between aroma enhancement and yield reduction is successfully solved. The whole set of scheme is synergistic in component, simple and convenient to operate, environment-friendly, good in stability and universality and suitable for large-area production, popularization and application.

This invention discloses a method for improving the aroma of regenerated fragrant rice. Belonging to the field of crop cultivation technology, this method significantly increases the content of the aroma compound 2-acetyl-1-pyrroline (2AP) in regenerated fragrant rice by simultaneously applying paclobutrazol or uniconazole (two plant growth regulators) during the tillering fertilizer application for the first-season fragrant rice, applying urea as a bud-promoting fertilizer before harvesting the first-season fragrant rice, and controlling the harvesting timing and stubble height of the first-season fragrant rice. Simultaneously, it can stabilize or increase the yield of fragrant rice, achieving stable or increased yield while improving the aroma. This invention is beneficial for improving the rice quality of regenerated fragrant rice and promoting its production.

The invention discloses an intelligent management method for rice planting and fertilization. The intelligent management method is jointly constructed by a hereditary characteristic analysis module, a field data acquisition module, an intelligent decision-making module and a precise fertilization operation module. The method has the advantages that 1) genetic information identification of rice germplasm resources and variety breeding characteristics are brought into a fertilization decision core, so that genetic-environment-cultivation multi-dimensional coupling optimization is realized; the method has the advantages of being simple in operation, convenient to operate, capable of achieving fertilization precision, quality specialization and benefit maximization according to the quality forming rule of special varieties (such as rice flour rice, selenium-rich rice and morning and evening fragrant rice), improving the fertilizer utilization rate through real-time monitoring and dynamic feedback, and enabling the quality of the special rice to be more stable.

The application discloses a rice stigma width regulation gene qSTB-8 and application of an encoded protein thereof, a nucleotide sequence of the rice stigma width regulation gene qSTB-8 is shown as SEQ ID NO. 1, and the application is selected from any one or two or more of the following: (1) application in regulation of rice stigma width; (2) application in improvement of rice stigma exposure rate breeding; (3) application in improvement of rice cross-pollination rate breeding. The application is configured by hybridization of a wide-stigma indica rice maintainer line Chuan 345B and a narrow-stigma high-quality indica rice maintainer line Chuan 106B into a BC4F5 positioning population, then a method of map-based cloning is used, SSR molecular markers are used for preliminary positioning, and finally qSTB-8 is finely positioned in a 11.2 kb segment between markers SG930 and SG950. Gene function analysis of qSTB-8 shows that a transgenic line Chuan 106B has a wide-stigma trait.

The designed product is a flat product, omitting left view, right view, top view, and bottom view.

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.

The invention belongs to the field of rice germplasm resource science, and particularly relates to an excellent local rice germplasm resource Sichuan Dechang fragrant rice fragrance gene as well as an identification method and application thereof. According to the Dexchang fragrant rice OsBADH2 gene, a genome of Nipponbare rice is taken as a reference genome, and a seventh exon of the Dexchang fragrant rice OsBADH2 gene is subjected to 5bp base insertion and 13bp base deletion. The method comprises the following steps: carrying out molecular marking on a Dhuchang fragrant rice OsBADH2 gene, amplifying a fragrant gene of the Dhuchang fragrant rice, and carrying out electrophoresis detection on a banding pattern and sequences of a second exon and a seventh exon of the fragrant gene. The method is beneficial for determining whether the rice is a genotype with fragrance or not, and important high-quality resources are provided for cultivation of fragrant rice varieties and development of high-end fragrant rice products.
