摘要
马铃薯(Solanum tuberosumL.)是庆阳市第三大粮食作物,早熟菜用型马铃薯发展迅速,但品种单一、产量低等因素影响该区早熟马铃薯产业发展。为筛选出适宜庆阳市早熟优质马铃薯新品种,提高产量和品质,以早熟品种‘费乌瑞它’为对照,对10个早熟马铃薯品种进行生物学特性、丰产性和商品性比较试验。结果表明,‘LK99’和‘尤金’2个品种田间长势强,农艺性状好,商品性状好,商品薯率85.3%以上;产量高,分别为27247和26563kg/hm2,较对照‘费乌瑞它’分别增产11.9%、9.1%,差异达到极显著水平,可作为该地区中早熟马铃薯品种示范推广。‘早大白’、‘中薯4号’和‘克新4号’3个品种产量中等,但生育期短,可作为该地区早熟品种示范推广。
Potato (Solanum tuberosum L.) is the third largest food crop in Qingyang City. Recently, the cultivated area of early maturing table stock potato varieties increases rapidly. However, limited varieties available for farmer's choice and low yield affect the development of the early maturing potato industry in Qingyang City. In order to find the excellent early maturing potato varieties with high yield and quality,'Favorita', an early maturing variety, was selected as a control, and the biological characters, yields and marketabilities of ten other early maturing potato varieties were evaluated in a field experiment. The growth, agronomic characters and marketabilities of 'LK99' and 'Youjin' were better than those of other varieties. The yield was 27 247 and 26 563 kg/ha, respectively, which increased by 11.9% and 9.1% compared with 'Favorita', and the differences was highly significant. The marketable tuber percentage of 'LK99' and 'Youjin' was more than 85.3%.'LK99' and 'Youjin' could be used as medium-early maturing potato varieties. The yields of 'Zaodabai','Zhongshu 4' and 'Kexin 4' were medium, but their growth duration was short. These three varieties could be planted as the early maturing potato varieties in Qingyang City.
