摘要:以陇薯6号为对照,在天水农业科学研究所中梁试验站对引进的10个品种(系)进行了比较试验。结果表明,青薯10号、定薯3号和大同里外黄折合产量较高,分别为35 585、28 080、27 846 kg/hm2,较对照品种陇薯6号分别增产66.56%、31.43%、30.33%,商品薯率分別为76.73%、70.78%、78.89%。这3个品种(系)生育期田间长势强,单株结薯数、单株薯重、抗病性等综合性状优良,适应性好,可在天水地区推广种植。

Abstract:In order to screen out high quality potato cultivars suitable for upland planting in Tianshui city and improve yield and quality,longshu 6 was used as the control, and the 10 cultivars (lines) were compared in Zhongliang Experimental Station of Tianshui Agricultural Research Institute for 2 years. The results showed that the yield of Qingshu 10, Dingshu 3, and Datong Liwaihuang was 35 585, 28 080 and 27 846 kg/hm2, which were 66.56%, 31.43% and 30.33% higher than that of Longshu 6, and the percentage of commercial tups was 76.73%, 70.78% and 78.89%, respectively. These threes cultivars (lines) have strong field growth during the growth period, with excellent comprehensive traits such as number of tubers per plant, tuber weight per plant, disease resistance, and good adaptability, which can be popularized in Tianshui area.

马铃薯是天水市主要农作物之一,是农业增效、农民增收的主要作物,栽培历史悠久,常年播种面积稳定在6万hm2左右,占全市粮田面积的16%左右。由于独特的自然条件,山旱地晚熟马铃薯生产是天水市马铃薯产业的优势,在农业经济中占有重要地位。近年来,随着国家马铃薯产业主食化战略提出和种植结构调整[1 - 2 ],马铃薯产业得到进一步发展,已成为农业增效、农民增收和脱贫致富的支柱产业之一。但由于种性退化、品种单一,病害严重、淀粉含量、商品薯率不高和产量水平相对低下等问题,导致马铃薯单产收益下降[3 - 4 ],制约着该区域马铃薯产业的发展。为筛选高产、优质、商品属性好、适应天水市种植的马铃薯新品种,国家马铃薯产业体系天水综合试验站引进国内育成的10个马铃薯新品种,在天水市农业科学研究所中梁试验站基地进行品种比较试验,对抗病性及丰产性进行鉴定,以期筛选出适宜天水山旱地种植的综合性状优良、高产、和抗病的马铃薯新品种。……
