The application discloses a rice germplasm yield prediction method and system for panicle type classification and growth period alignment. Firstly, time sequence images of a rice plot are acquired, and a ST-YOLO single panicle detection model is used to identify the growth stage of the rice and extract single panicle images. The single panicle images are input into a PP-LCNet multi-label classification model to synchronously identify the panicle type and the growth period, filter mature period data, and process the data by panicle type, so that the growth period alignment and the panicle type classification are realized, and the temporal and spatial feature noise introduced due to different phenology and morphology is eliminated. The geometric features of the detection frame are extracted at the single panicle scale, and the number, color, texture, spectrum, phenology and other features are extracted by using a Swin Transformer segmentation model at the group scale. Machine learning algorithms are used to respectively establish yield prediction models for different panicle types. The application effectively solves the problem of complex temporal and spatial noise interference in large-scale breeding tests, and realizes high-throughput, accurate and non-destructive rice yield prediction.

This invention discloses the application of the protein OsEAR9 in regulating rice plant height and yield. The amino acid sequence of the protein OsEAR9 is shown in SEQ ID NO:1. Experiments have shown that overexpression of the OsEAR9 gene in rice yields transgenic rice; this transgenic rice exhibits significantly increased plant height, panicle length, number of primary branches, number of secondary branches, number of grains per panicle, and yield per plant. Inhibition of the OsEAR9 gene in rice yields OsEAR9 knockout rice, i.e., OsEAR9 homozygous mutants; the OsEAR9 homozygous mutants show significantly reduced plant height, panicle length, number of secondary branches, number of grains per panicle, and thousand-grain weight, but do not affect yield per plant. Therefore, the protein OsEAR9 can regulate rice plant height, yield, and panicle shape. This invention has significant application value.

This invention discloses a method for cultivating transgenic rice with increased yield and plant height. This method achieves this by increasing the expression level and / or activity of the protein OsEAR5 in the recipient rice; the amino acid sequence of protein OsEAR5 is shown in SEQ ID NO:1. Experiments have shown that overexpression of the OsEAR5 gene in rice yields transgenic rice with significantly increased plant height, number of grains per panicle, number of primary branches, and yield per plant, while significantly decreasing the number of tillers. Inhibition of the OsEAR5 gene in rice yields OsEAR5 knockout rice, i.e., OsEAR5 homozygous mutants; these mutants show a significant increase in the number of primary branches, and a significant decrease in the number of grains per panicle and yield per plant. Therefore, the protein OsEAR5 can regulate rice plant height, yield, and panicle shape. This invention has significant application value.

This invention discloses a method for improving rice plant architecture using the CRISPR-Cas12i system, belonging to the field of genetic breeding technology. This method improves rice plant architecture without altering the amino acid sequence. It involves base substitution at the miR156 recognition site in the coding gene of IPA1, an important functional gene regulating plant architecture in the target rice variety. Using the principle of codon degeneracy, it screens for rice varieties with improved plant architecture where the amino acid sequence of the IPA1 coding gene remains unchanged. The improved rice has fewer tillers, longer panicles, and increased yield per plant compared to the target rice. The coding sequence of the wild-type IPA1 is shown in SEQ ID NO:1, and the amino acid sequence of the wild-type IPA1 is shown in SEQ ID NO:2. This method can be used for molecular design breeding of genetic traits.

This invention provides a high-precision automatic extraction method and system for phenotypic parameters of rice growth stages, belonging to the field of agricultural information technology. The invention identifies the rice growth stage by acquiring and preprocessing observational data containing canopy height information, and then matching phenotypic parameter definition rules from a rule base based on the growth stage. Plant height is determined by reference plane and height distribution statistics during the tillering or jointing stage. During the heading stage, panicle height and plant height are calculated separately by distinguishing between panicle and leaf tip. During the grain-filling stage, plant height is geometrically corrected based on lodging posture. The phenotypic parameter result set is then aggregated and output according to the growth stage, achieving unified semantics and stable calculation of plant height and panicle height across different growth stages, improving the accuracy of phenotypic parameters and comparability across growth stages.
