Comparison of Late-sowing Rapeseed Varieties Suitable for Mechanized Harvesting in Anhui along the Yangtze River from 2022 to 2023
[Objective]The aim was to explore the late sowing rapeseed varieties suitable for the climate characteristics of rapeseed production areas along the Yangtze River in Anhui province and suitable for mechanical harvesting.[Method]Thirteen rapeseed varieties with best-selling and large planting area in the market were selected as late sowing varieties for screening test.[Result]Qinyou 797,Yueyou 1203,Huiyou 50,Shengguang 168E and Zheda 622 had moderate growth period,high yield and good resistance,which could be used as late sowing varieties in Wangjiang county to further increase demonstration planting.The growth period of the two varieties of Qinshanyou 28 and Ning R101 was long,the resistance was better,and the yield level was higher.It was suitable for the rice-rapeseed rotation mode in Wangjiang county to be sown before October 20.The varieties of Yangguang 131,Shengguang 127 and Keyouza 2 had short growth period,general cold resistance and disease resistance,and had the advantage of short growth period.They could be further demonstrated and planted as rapeseed varieties of'rice-ratooning rice-rapeseed'mode in Wangjiang county.[Conclusion]The research provided the reference basis for the variety selection of late sowing rapeseed in Wangjiang county.
