拉萨引进马铃薯品种不同年份比较试验

Different Years Comparative Test of Introduced Potato Varieties in Lhasa

优良的马铃薯品种是取得高产稳产的重要基础,西藏马铃薯存在主栽品种少,退化严重的问题,阻碍着西藏马铃薯产业的发展。为了推进西藏马铃薯育种工作,筛选出适合西藏种植的马铃薯新品种,从国内引进9个马铃薯品种,以‘鄂薯10号’和‘艾玛土豆’为双对照,在拉萨市进行了一点两年品种比较试验,对9个马铃薯品种的植株形态特征、植株性状、块茎外观性状、产量表现进行调查和分析。结果表明,‘青薯9号’和‘冀张薯12号’综合性状表现优良且稳定性好,‘青薯9号’产量最高,达3713 kg/667m^2,商品薯率47%,‘冀张薯12号’产量达3411 kg/667m^2排3位,商品薯率最高为56.0%。因此,2个品种适宜在拉萨地区种植,可进一步试验有望成为西藏马铃薯的主栽品种。

Excellent potato varieties are an important basis for high and stable yield.There are few main potato variety and serious degradation in Tibet,which hinders the development of potato industry in Tibet.In order to promote potato breeding in Tibet and select new potato varieties suitable for cultivation in Tibet,nine potato varieties were introduced from domestic and compared in Lhasa for experiment of two-year in the same site with double controls varieties‘Eshu 10’and‘Emma Potato’.Investigation and analysis of plant morphological characteristics,plant characteristics,tuber appearance traits and yield performance were conducted.The results showed that‘Qingshu 9’and‘Jizhangshu 12’were well performed and stable.The yield(3713 kg/667m^2)of‘Qingshu 9’was the highest,the marketable tuber percentage was 47%,the yield(3411 kg/667m^2)of‘Jizhangshu 12’ranked the third,and the marketable tuber percentage(56.0%)was the highest.Therefore,‘Qingshu 9’and‘Jizhangshu 12’have potential to grow in Lhasa,but need further tests as the main potato cultivar in Tibet.
