马铃薯抗病增产优质中早熟新品种筛选试验
Screening Test of New Potato Varieties with Mid-early Maturity, High Disease Resistance, Yield Increase and Good Quality
【摘要】 为筛选出适宜天水市灌溉区种植的中早熟抗病增产优质马铃薯新品种,以‘克新2号’为对照,对引进的9个马铃薯品种进行生物学特性、适应性、抗病性、商品性、产量等综合性状的比较。结果表明,‘希森6号’‘荷兰15号’‘冀张薯12号’表现出较好的适应性,块茎性状好,商品薯率高,增产增效明显;商品薯率分别为92.51%、93.20%、92.64%,产量分别为54 540,53 280和48 767 kg/hm~2,较对照分别增产22.32%、19.50%、9.37%,分别增收12 377.60,11 099.20和3 835.20元/hm~2,可考虑作为川水地区大面积示范推广种植的中早熟优势品种。
【Abstract】 Nine introduced potato varieties were introduced and compared with the control variety ’Kexin 2’ for biological characteristics, adaptability, disease resistance, marketable tuber percentage, and yield in order to screen out the potato varieties with mid-early maturity, high disease resistance, yield increase and good quality suitable for planting in Tianshui irrigation area. ’Xisen 6’, ’Helan 15’ and ’Jizhangshu 12’ showed good adaptability, good tuber characters, high marketable tuber percentage, and yield and income increase. The marketable tuber percentage was 92.51%, 93.20%,and 92.64%, respectively. The yield of marketable potatoes for these three varieties was 54 540, 53 280 and 48 767 kg/ha,respectively, increased by 22.32%, 19.50% and 9.37%, respectively, compared with the control variety. The income was increased of 12 377.60, 11 099.20 and 3 835.20 Yuan/ha, respectively. These three varieties could be considered for planting in a large-scale demonstration and promotion as mid-early maturity dominant varieties in irrigation area.
