Echo Russet is a medium- to late-maturing selection with long, large, russeted tubers. Total yields are similar to those of Russet Burbank and Ranger Russet, however Echo Russet produced significantly greater yields than Russet Norkotah. Further, Echo Russet produced significantly higher US No. 1 yields when compared to these standard varieties (6—29% more). Echo Russet has high protein, high specific gravity, light fry color, low acrylamide level, and few internal and external tuber defects. In three years of evaluations in U.S. Western Regional Potato Variety Trials, post-harvest merit scores for fresh and processing qualities were high for Echo Russet when compared to standard varieties. Echo Russet is resistant to Fusarium dry rot, Pectobacterium (syn. Erwinia) soft rot, and common scab. Echo Russet exhibits moderate resistance to Verticillium wilt, early blight, Potato virus Y (PVY), Potato leaf roll virus (PLRV), Potato mop top virus (PMTV), and corky ring spot. The preponderance of resistances to major diseases gives Echo Russet great potential for organic production and sustainable farming systems.

Echo Russet:块茎适销高产、加工质量好、块茎缺陷少的赤褐色马铃薯品种

Echo Russet 是一种中晚熟品种,具有长而大的黄褐色块茎。总产量与 Russet Burbank 和 Ranger Russet 相似,但 Echo Russet 的产量明显高于 Russet Norkotah。此外,与这些标准品种相比,Echo Russet 产生了显着更高的美国第一产量(6-29%)。Echo Russet具有高蛋白、高比重、油炸颜色浅、丙烯酰胺含量低、块茎内外缺陷少等特点。在美国西部地区马铃薯品种试验的三年评估中,与标准品种相比,Echo Russet 在新鲜和加工质量方面的采后品质得分较高。Echo Russet 对干腐镰刀菌、Pectobacterium(syn.Erwinia) 软腐病和普通病斑。Echo Russet 对黄萎病、早疫病、马铃薯 Y 病毒(PVY)、马铃薯卷叶病毒(PLRV)、马铃薯拖把顶病毒(PMTV) 和软木环斑病具有中等抗性。对主要疾病的抵抗力优势使 Echo Russet 在有机生产和可持续农业系统方面具有巨大潜力。
