Abstract:Rice grain type, a key trait affecting both yield and quality, is evaluated using multiple indicators, including grain length, width, and thickness. This article aims to summarize the latest progress and current status of rice grain type breeding, and provide an in-depth analysis of grain type breeding development in Jilin Province. In Jilin Province, round-grain varieties dominate both in the number of officially approved varieties and in market share, demonstrating their significant advantage in this region. The round-grain variety Jijing 332 exhibits highyielding potential, excellent grain quality, strong stress resistance, ideal plant type, and wide adaptability, and was officially approved in 2024(Approval No. 20241009). The breeding and promotion of this variety play a significant role in advancing round-grain rice development in Jilin Province, while also helping to stabilize the local market and sustain the competitiveness of local round-grain varieties.
