Five fresh market potato cultivars commonly grown in western Washington were evaluated against Potato virus Y (PVY) O, NTN, and N-Wi using inoculated PVY-free plantlets in the greenhouse in 2015 and successive generations of seed tubers from foliar inoculated plants in 2016, 2017, and 2018. Mosaic displayed strongly on all cultivar by strain combinations, except All Blue by PVY^O. Russet Burbank and Yukon Gold infected with PVY^O had highest area under symptom progress curve values for leaf drop across all cultivars and years. Yields mostly were lowest for PVY^O. More cracked tubers developed on G3 tubers in the field than greenhouse G2 or G1 plants. Chieftain infected with PVY^O and PVY^NTN, and Yukon Gold with PVY^N-Wi had marked increases in tuber cracking by 2018. Cracking began at early plant growth stages; seed tuberborne rather than current season infections had higher cracking incidence; cracking became prevalent with succeeding seed tuber generations; cracking did not contribute to tuber weight loss during storage; and, PVY and tuber cracking substantially impacted yield.

通过三个连续的马铃薯世代，三个菌株Y病毒对五个新鲜马铃薯品种的叶薯和块茎反应

2015年，使用温室中未接种PVY的小植株以及2016年从叶状接种植物中连续繁殖的五代，对华盛顿西部常见的五个新鲜马铃薯栽培品种进行了抗马铃薯病毒Y（PVY）O，NTN和N-Wi的评估，2017年和2018年。除PVY ^O的“ All Blue”外，马赛克在所有菌株中均表现出了较强的菌株组合。在所有品种和年份中，感染PVY ^O的Russet Burbank和Yukon Gold在症状进展曲线值下的叶落面积最大。PVY ^O的产量最低。与温室G2或G1植物相比，田间G3块茎上发育的裂块茎更多。头目感染了PVY ^O和PVY ^NTN，到2018年，带有PVY ^N-Wi的Yukon Gold的块茎裂化显着增加。裂化始于植物早期生长阶段。种子块茎而不是当前季节的感染具有更高的破裂发生率；在随后的种薯世代中，裂化变得普遍。在存储过程中开裂不会导致块茎减重；而且，PVY和块茎开裂大大影响了产量。
