Abstract:

This study presented a preliminary report on the planting performance of 13 new rapeseed varieties in the Hangzhou area. Through conducting planting experiments in specific areas of Hangzhou，the performance of 13 rapeseed varieties in terms of growth period，main economic traits，field occurrence of Sclerotinia rot，lodging and cold resistance was investigated. The results showed that the growth period of 13 rapeseed varieties after planting in Hangzhou area was 208-220 days，the yield of 667 m² was 56.45-128.23 kg，and the occurrence degree of Sclerotinia rot of each variety was "mild"，lodging resistance was "moderate" or "good"，and the cold resistance was "good". Based on the yield measurement results，the 667 m² yield of Zhenongyou 12 was as high as 128.23 kg，and it had good disease resistance，lodging resistance and cold resistance，which can be promoted for planting in the Hangzhou area. This study provided an important reference basis for screening out new rapeseed varieties suitable for planting in the Hangzhou area，which are high-yielding，high-quality and have strong stress resistance.
