Abstract:

To accelerate the promotion and application of new high-yield and high-quality rice varieties,this study conducted a comprehensive evaluation of agronomic traits and field performance of 10 tested rice varieties in Huzhou City. The results demonstrated that among the tested indica-japonica three-line hybrid rice varieties,Jiayou Zhongke 20-12 exhibited a shorter maturity period and higher average daily yield,making it suitable for intercropping with other crops. Among japonica-type three-line hybrid rice varieties,Changyoujing 10 demonstrated moderate growth period,high yield,and excellent stress resistance. In conventional japonica-type rice varieties,Jiayou 93 showed moderate maturity period,high yield,and good stress resistance. The results provide reference for large-scale demonstration and promotion of high-yield hybrid rice varieties in Huzhou City.
