ABSTRACT
A new variety "Zhebei 3(Zhejiao Pharmaceutical 2018002)" was selected and bred from multi seeded Fritillaria thunbergii mutants by systematic breeding method. From 2012 to 2016, the traits assessment, disease resistance appraisal, plot ratios and regional trials of the variety were continuously carried out. The results showed that "Zhebei 3" emerged early and had late seedlings. The average growth period was about 100 days, which was 6 days and 12 days higher than the "Zhebei 1" and "Zhebei 2". The average yield was 5 095.5 kg·hm~(-2), which was 14.42% and 17.71% higher than of the control respectively. The average proliferation rate of bulbs was 261.2%, which was 37.46% and 31.58% higher than that of the control, respectively. The propagation coefficient of bulbs was about 1∶2.6, and the total amount of peimine and peiminine was 0.172 2%, which was 4.49% and 29.47% higher than the control, respectively. The identification of disease resistance showed that it was resistance to bulb stem(soft) rot, better than the control. "Zhebei 3" has stable characters, high yield, good quality, strong disease resistance, and moderate propagation coefficient which is suitable for planting in Zhejiang province.
