摘　　要：目的选育繁殖系数高、丰产的半夏新品种,阐明“中钰半夏1号”的选育过程,明确该新品种的推广价值。方法收集全国不同地区半夏种质并建立半夏种质资源圃,经过综合评比最终选择以复叶多、双珠芽的贵州省农家优良品系DB-CL-03为繁育对象,采用集团化选育连续择优去劣,通过品比试验、区域试验,优选出符合新品种要求的“中钰半夏1号”。结果“中钰半夏1号”的复叶数平均5枚,繁殖系数约为9.2,是对照的2.6倍“。中钰半夏1号”平均每亩产量291.47 kg,较对照增产44.38%;总有机酸(以琥珀酸计)含量比对照提高15.2%。结论“中钰半夏1号”繁殖系数高、丰产性好、性状表现稳定,适宜引种于中国西南部和中部半夏种植区,具有良好的推广价值。Objective To breed new cultivar of Pinellia Yernata(P. ternata) with high reproduction coefficient and yield, to clarify the breeding method of P. ternata "Zhongyu No.1", and define the value of the popularization.Methods The germplasm of P. ternata were collected in different regions of China. The germplasm resource nursery of P. ternata was established. Line "db-cl-03" from Guizhou Province with compound leaves and double tubercles were selected as the breeding materials. The line breeding was adopted to continuously select the better individual and eliminate the bad.Through varietal comparative test and regional experiment, Zhongyu No.1 met the requirements.Results The average number of compound leaves of Zhongyu No.1 was 5. And the reproductive coefficient was about 9.2, 2.6 times higher than the control. The average fresh yield of tuber was 291.47 kg/666.6㎡, which was 44.38% higher than the control.The total organic acids of Zhongyu No.1(calculated by succinic acid) increased by 15.2% than the control.Conclusion P. ternata Zhongyu No. 1 has higher reproductive coefficient, good yield. It is suitable to be introducted into P. ternata planting regions in southwest and central of China.
