青海省湟中区马铃薯品种(系)对比试验研究

Comparative Experimental Study on Potato Varieties(Lines)in Huangzhong District of Qinghai Province

从青海省农科院引进9个马铃薯品种(系),对其生育期、田间性状、块茎性状、经济性状、产量等方面进行对比分析。结果表明,较对照青薯2号,综合性状较好的品种(系)有4个,依次是通薯1号、青薯9号、青薯10号和15-01-01。其中,通薯1号产量及商品率均为最高,分别为53976.94 kg/hm 2和89.04%,较对照青薯2号增产23.73%,商品率提高11.34%,但其淀粉和干物质含量均较低,是菜用型品种。其余三个品种(系)也较适合在本区推广种植。

Nine potato varieties(lines)were introduced from Qinghai Academy of Agricultural Sciences,and their growth period,field characteristics,tuber characteristics,economic characteristics,yield and other aspects were compared and analyzed.The results showed that there were four varieties(lines)with better comprehensive traits compared to the control Qingshu 2,namely Tongshu 1,Qingshu 9,Qingshu 10,and 15-01-01.Among them,Tongshu 1 has the highest yield and commodity rate,with 53976.94 kg/hm 2 and 89.04%respectively.Compared with the control Qingshu 2,it has increased yield by 23.73%and commodity rate by 11.34%.However,its starch and dry matter content were relatively low,making it a vegetable variety.The other three varieties(lines)are also more suitable for promotion and planting in this area.
