    Growth Traits and Yield Performance of Japonica Hybrid Rice Bred by the New Strategy in the Yangtze River Region of China by Yutiao Chen, Jiayu Song, Xiaofu Hong, Huaijie Zhang, Tiejun Hu, Guanglong Zhu

    Published 2025-01-01
    “…Despite the successful breeding of hybrid japonica rice by the new strategy (the female parent with a restorer line containing an appropriate proportion of indica rice genes) in China, it remains unclear whether these cultivars exhibit a similar yield performance with the traditional high-yield hybrid cultivars in the Yangtze River region. Therefore, two field experiments were conducted in Fenghua City and Yuyao City, China, during the two growing seasons in 2019 and 2020. …”
