安康市中早熟马铃薯新品系比较试验

Comparative Trial of New Mid-Early Maturing Potato Clones in Ankang

摘要: 为选育适宜安康地区种植的早熟、商品性好和产量高的马铃薯新品系，2015年以当地种植面积较大的两个早熟品种为对照对6个选育的马铃薯早熟品系的物候期、农艺性状、经济性状和产量进行调查。结果表明，S0406-17生育期62 d、亩产1090 kg，商品薯率80.6%，综合性状表现优，可在安康地区进行下一步生产试验和示范。1003-3、0903-34，平均亩产高，但商品薯率低，需进一步种植观察。

Abstract: Six new early maturing potato clones were bred and compared with two potato cultivars in order to select new potato clones with early maturity, high marketable tuber percentage and yield in Ankang area. The materials selected were evaluated for their phenology, agronomic characters, economic characters and yield. The results showed that “S0406-17” had high per-mu yield of 1090.0 kg, short growth duration of 62 days, and high marketable tuber percentage of 80.6%. The com-prehensive property was excellent. Therefore “S0406-17” could be included in production of trial and demonstration in the future. “1003-3” and “S0406-17” were with high yield, but the marketable tuber percentage was low, which needed further planting observation.
