Field Performance and High-yield Cultivation Technique of Hybrid Rice New Combination Yongyou9
Abstract：Yongyou9,a new later rice cultivar of indica-japoniea hybridization,was introduced to Fuding City in 2009.The results of a two-year trial experiment showed that the rice performed high and stable in yield and good grain quality.However,it was moderately susceptible to rice blast and bacterial blight disease,and susceptible to basal rot,rice false smut and rice planthopper.At maturity stage,it showed weaker in cold tolerance and more susceptible to bacterial wilt than japonica rice.In order to ensure high and stable yield,the cultivation technique of Yongyou9 should pay attention on seed sterilization,fostering strong seedling,transplanting enough basic seedling,strengthening fertilizer and water management and timely insect disease control.
