en.Wedoany.com Reported - Zhongke Quanyin, a subsidiary of China Seed Corporation, has obtained a national invention patent titled "A QTN Data Analysis Method for Intelligent Navigation Breeding Based on Large Models." This patent has been integrated into Zhongke Quanyin's intelligent design breeding technology system for rice and is being widely applied in actual breeding work.
The agricultural value of this patent is concentrated in the decision-making stage of rice breeding. Traditional breeding requires repeated screening among a large number of parental materials, cross combinations, field performance, and multiple generations of progeny materials, resulting in long cycles, extensive trials, and heavy reliance on the experience of breeding experts. The QTN data analysis method incorporates quantitative trait loci, phenotypic performance, genetic effects, planting environments, and literature validation data into a single analytical chain, enabling breeding teams to assess potential trait performance and adaptability outcomes before selecting parents, designing crosses, and screening progeny materials.
The key to breeding new rice varieties is not just identifying a single desirable trait, but combining multiple traits such as yield, quality, disease resistance, stress tolerance, plant architecture, growth period, and regional adaptability into stable materials. By learning and analyzing breeding data and literature, this method provides decision support for parental screening, cross combination prediction, progeny material selection, and variety adaptability assessment, helping breeders reduce ineffective combinations and increase the probability of superior materials entering field trials and subsequent breeding processes.
The RiceNavi intelligent agent technology system developed by Zhongke Quanyin has moved from theoretical models to the application stage of intelligent design breeding for rice. Its role is not to replace field trials, but to conduct correlation analysis of gene loci, parental materials, target traits, and suitable planting environments before trials, making the breeding pathway clearer. Field planting, trait investigation, line identification, and regional trials remain essential steps in variety development, with the data analysis method primarily serving front-end navigation and process decision-making functions.
This patent has already served multiple breeding research teams in China. For scientific breeding institutions, rice breeding data has long been scattered across material banks, trial records, research papers, gene locus databases, and field phenotypic data. The challenge lies in converting this information into executable breeding plans. After the QTN data analysis method enters the actual breeding system, it can transform accumulated data into parental configuration, combination evaluation, progeny selection, and regional adaptability assessment.
This patent authorization for Zhongke Quanyin focuses on the production-oriented application of intelligent design breeding for rice. Its technical chain revolves around QTN loci, phenotypic data, genetic effect values, parental materials, cross combinations, progeny screening, and variety adaptability, ultimately serving more efficient breeding of new rice varieties and decision-making for research teams.
