In order to select excellent varieties of Zizania latifolia suitable for planting in Yuyao area,we conducted comparative experiments on the agronomic traits,economic traits,maturity period,and disease resistance of seven Zizania latifolia varieties(lines)in 2023.The results showed that from the entire growth period,Zhenong 7 had the least incidence of rust and sesame spot disease,good heat resistance and good fertility,and the earliest production time of autumn Zizania latifolia(September 1st).It had excellent tillering performance,the most effective seedlings,and good shape.The 667 m2 yield and benefits of autumn Zizania latifolia were 17.5%and 24.6%higher than those of the control August Zizania latifolia,respectively.It is a new variety(line)with excellent comprehensiveness,high yield,and good benefits,and can be planted as a local early maturing variety.Among the several introduced varieties(strains),Huishan Zizania latifolia had tall plants,high yield rate,similar production period to the control August Zizania latifolia,and moderate disease resistance.The 667 m2 yield was 22.4%higher than that of the control August Zizania latifolia,and the 667 m2 benefit was 22.4%higher than that of the control August Zizania latifolia,making it suitable for local promotion and planting.
