摘要
采用新品种对商业种植者来说是一个挑战。为了解北达科他州立大学两个潜在马铃薯品种的最佳施氮量（90、134、179和224 kg N hm -1）和行距（15、23和31 cm），于2019年和2020年在北达科他州进行了研究。先进的芯片选择ND7799c-1和ND7519-1与芯片行业标准Dakota Pearl进行了比较。2019年，以23厘米行距种植的nd779c -1与Dakota Pearl的适销产量相似。2020年，ND7519-1和ND7799c-1的行间距为15 cm和23 cm，产量与达科塔珍珠相似。施氮量在2019年和2020年对产量和切屑质量没有影响。与2020年的达科他珍珠相比，先进选种在收获后一个月的蔗糖和葡萄糖水平较低。ND7799c-1保存了8个月，ND7519-1保存了6个月，芯片质量下降。本研究表明，ND7799c-1和ND7519-1有潜力成为北方平原上成功的薄片加工品种。
Nitrogen and Spacing Requirements for Advanced Chipping Selections ND7799c-1 and ND7519-1
Adoption of new cultivars is challenging for commercial growers. To understand the best nitrogen fertilization rate (90, 134, 179, and 224 kg N ha-1) and within-row spacing (15, 23 and 31 cm) for two potential potato cultivar releases from North Dakota State University, a study was carried out in 2019 and 2020 in North Dakota. The advanced chipping selections ND7799c-1 and ND7519-1 were compared to a chip industry standard, Dakota Pearl. In 2019, ND7799c-1 grown at 23 cm within-row spacing had similar marketable yield to Dakota Pearl. In 2020, ND7519-1 at all within-row spacings, and ND7799c-1 at 15 and 23 cm within-row spacing, yielded similarly to Dakota Pearl. Nitrogen rate did not affect yield or chipping quality in 2019 or 2020. The advanced selections had lower sucrose and glucose levels one month after harvest compared to Dakota Pearl in 2020. ND7799c-1 stored for 8 months, and ND7519-1 for 6 months, before chip quality declined. This research demonstrates the potential for ND7799c-1 and ND7519-1 to be successful chip processing cultivars for the Northern Plains.
期刊介绍：
The American Journal of Potato Research (AJPR), the journal of the Potato Association of America (PAA), publishes reports of basic and applied research on the potato, Solanum spp. It presents authoritative coverage of new scientific developments in potato science, including biotechnology, breeding and genetics, crop management, disease and pest research, economics and marketing, nutrition, physiology, and post-harvest handling and quality. Recognized internationally by contributors and readership, it promotes the exchange of information on all aspects of this fast-evolving global industry.
