半夏优质高产品种比较试验结果初报

为鉴定和评价毕节地区生产上所用半夏栽培品种的丰产性、适应性、稳产性和品种的特性特征,为品种区域布局提供科学依据。采用区组设计,对尖叶多杆(大个)、河镇1号、尖叶高杆半夏、圆叶短杆黑叶半夏、威宁野生半夏(CK)、海镇2号、黑石头镇黑石村半夏7个品种的产量相关性状进行对比分析。圆叶短杆黑叶半夏单位鲜产居第一,为7 966.5 kg/hm2,较对照增产334.6%,商品半夏比率和单粒重均远高于对照。其次黑石头镇黑石村半夏单位鲜产为7 320.0 kg/hm2,较对照增产299.3%,商品半夏比率为73.12%,但单粒重较低仅为1.2 g,仅高于对照,比其他低。建议圆叶短杆黑叶半夏作主推品种在大面积生产上应用;黑石头镇黑石村半夏为次要品种在生产上应用。

Preliminary Study on Comparative Test of Pinellia ternate Varieties with Good Quality and High Yield

The study on the identification and evaluation of the productivity,adaptability and yield stability and variety characters of Pinellia ternate cultivars used in the production was conducted which provide aimed to scientific basis for variety regional distribution.In the field test with block design,the relative yield characters of 7 P.ternate cultivars such as Jianyegaogan,Hezhen1,Jianyegaogan P.ternate,Yuanyeduanganheiye P.ternate,Weiningyiesheng P.ternate(CK),Haizhen 2 and Heishitouzhenheishichun were compared and analyzed.The fresh yield in unit area of Yuanyeduanganheiye ranked first place,being 7 966.5 kg/hm2 and 334.6% higher than CK.Its commodity percentage and single grain weight were much higher than CK.Heishitouzhenheishichun followed and had the fresh yield in unit area of 7 320.0 kg/hm2,being 299.3% higher than CK.Its commodity percentage of 73.12%,and single grain weight were lower,being only 1.2 g,slightly higher than CK and lower than other cultivars.It was suggested to take the cultivar Yuanyeduanganheiye P.ternate as the main cultivar that was applied in the production at lavge area and the cultivar Heishitouzhenheishichun as the secondary cultivar that was applied in the production.
