Comparison experiment of single season japonica(glutinous)rice varieties in southern Anhui in 2023
In order to screen for single season high-quality and high-yield japonica(glutinous)rice varieties suitable for planting in the southern Anhui region,this study selected 13 varieties of japonica(glutinous)rice,including Zhennuo 29,zhefengnuo 188 and Wankennuo No.2,as well as one control variety,Dangjing No.8,to conduct a comparative experiment of single season rice varieties at the experimental site in the southern Anhui region.Comparative analysis was conducted from the aspects of agronomic traits,comprehensive resistance,and economic traits of the varieties.The results showed that the entire growth period of each variety is 131 to 141 days,all other varieties had a longer growth period than the control variety Dangjing No.8(133 days),except for Danghe 715(131 days).The plant height of each variety was 80.8 to 112.0 cm,and the tillering ability was average or strong.The plant type was moderate,compact or compact,and the varieties with better agronomic traits include Zhennuo 19,Ningxiangjing No.9,Huijing 805,and Nanjing 5055.Varieties with a yield exceeding 9 000 kg/hm2 included Ningxiangjing No.9(9 758.2 kg/hm2),Zhennuo 19(9 361.1 kg/hm2),Zhefengnuo 188(9 215.3 kg/hm2),Wankennuo No.2(9 016.5 kg/hm2),and Nanjing 5055(9 005.2 kg/hm2).Among them,Zhennuo 19 and Ningxiangjing No.9 had a more severe occurrence of rice blast in the field,while Ningxiangjing No.9 and Nanjing 5055 had a more severe occurrence of sheath blight and white leaf blight in the field.In terms of cultivation and management,attention should be paid to the prevention and control of these diseases.Based on the yield and resistance performance of various varieties,single season japonica(glutinous)rice varieties Wankennuo No.2,Zhennuo 19,and Zhefengnuo 188,Ningxiangjing No.9,and Nanjing 5055 were selected for promotion and cultivation in the region.They could be used as high-quality rice for production,and disease prevention and control must be strengthened during the planting period.
