“…Seed pieces were planted 35 cm apart at a depth of 15-20 cm. The six cultivars included Russet Burbank, Alturas (Novy et al 2003), GemStar Russet (Love et al 2006), Ranger Russet (Pavek et al 1992), Summit Russet (Love et al 2005) and Russet Norkotah (Johansen et al 1988). These six cultivars represent a very wide range of seasonal growth patterns and water requirements.…”

The ability to minimize potato yield and quality losses due to drought can be greatly improved by understanding the relative responses of different cultivars to seasonal variations in water supply. To address this need, we initiated a 2 year field experiment to determine the responses of the six potato cultivars to different seasonal drought patterns, including 1) full season irrigation at 100 % ET, 2) irrigation at 100 % ET terminated during late bulking , 3) full season irrigation at 70 % ET , 4) irrigation at 70 % ET terminated during late bulking , and 5) a gradual reduction in irrigation from 100 % ET during tuber initiation through early bulking, to 70 % ET during mid-bulking, and 50 % ET through late bulking. GemStar Russet and Ranger Russet, two medium-late maturing cultivars, generally produced the highest yields across the range of drought treatments, but both were fairly sensitive to changes in drought severity. Alturas, a late maturing cultivar, produced relatively high yields with full irrigation, but exhibited the greatest sensitivity to increasing drought severity, particularly when severe late-season water deficits were imposed. Yields for the early maturing cultivar Russet Norkotah were relatively low overall, but it was the least sensitive to changes in drought severity, particularly when late season drought was imposed. Russet Burbank produced comparatively high total yields across the range of drought treatments, but U.S. No. 1 yields were substantially reduced by each seasonal drought pattern. However, it was less sensitive to changes in drought severity than GemStar Russet, Ranger Russet and Alturas. Total and U.S. No. 1 yields for Summit Russet were low for each drought treatment and it exhibited intermediate sensitivity to changes in drought severity. GemStar Russet had the highest water use efficiency based on U.S. No. 1 yield.Resumen Se puede mejorar grandemente la habilidad para minimizar las pérdidas en rendimiento y calidad de papas debido a la sequía, mediante el entendimiento de las respuestas relativas de diferentes variedades a variaciones estacionales en el suministro de agua. Para atender esta necesidad, iniciamos un experimento de campo por dos años para determinar las respuestas de seis variedades de papa a diferentes patrones de sequía estacional, incluyendo, 1) riego completo en el ciclo al 100 % ET, 2) riego al 100 % ET terminando durante el fin de la tuberización, 3) riego durante todo el ciclo a 70 % ET, 4) riego al 70 % ET terminando al final de la tuberización, y 5) reducción gradual de riego de 100 % ET durante la iniciación de la tuberización a lo largo del llenado temprano, a 70 % ET durante la mitad del llenado, y 50 % ET a lo largo de la tuberización tardía. Gem Star Russet y Ranger Russet, dos variedades de intermedias a tardías, generalmente produjeron los rendimientos más altos a lo largo de la amplitud de los tratamientos de sequía, pero ambas fueron muy sensibles a los cambios de la severidad de la sequía. Alturas, una variedad tardía, produjo rendim...

“…The PVY O or common strain typically causes a green and yellow mottle or mosaic pattern in infected foliage though the symptomatic expression in leaves can vary among cultivars. A mild "latent" infection has been observed in Russet Norkotah (RN), a fresh market cultivar released in 1987 (Draper et al 2002;Henn et al 2006;Johansen et al 1988). …”

Successful selections of Russet Norkotah lines have produced larger, more vigorous vines and higher yields than the standard Russet Norkotah (RN). Potato Virus Y (PVY), while producing mild or "latent" symptoms in this cultivar, has been shown to significantly reduce yields. To determine PVY's effect on yield of a RN selection, PVY infected RN and Russet Norkotah selection 3 (RN3) yields were compared after planting in Hermiston, Oregon in 2001, 2003. After emergence, individual plants were ELISA tested for PVY multiple times during the growing season to confirm infection. Plants were categorized when infected; 1) current season, 2) seed borne or 3) "no PVY". At harvest, total and marketable yield data were collected. RN3 produced higher total yields than RN, regardless of infection categories. Highest yield reductions of RN and RN3 due to PVY were in the following order; seed borne PVY >>current season PVY >>no PVY.Resumen Las selecciones exitosas de líneas de Russet NorKotah han producido follajes más grandes y vigorosos, y mayores rendimientos, que la Russet NorKotah (RN) convencional. El virus Y de la papa (PVY), mientras produce síntomas ligeros o "latentes" en esta variedad, se ha demostrado que reduce significativamente los rendimientos. A fin de determinar el efecto del PVY sobre el rendimiento de una selección de RN, se compararon los rendimientos entre RN infectada y una selección 3 de NorKotah (RN3), después de plantar en Hermiston, Oregon, en 2001, 2003 y 2006. Después de la emergencia se hicieron pruebas de ELISA para PVY muchas veces a plantas individuales durante el período de crecimiento para confirmar la infección. Cuando se infectaron, las plantas se categorizaron: 1) durante el crecimiento, 2) de la semilla, o 3) "no PVY". A la cosecha se tomaron datos de rendimiento total y comercial. RN3 produjo mayor rendimiento total que RN, independientemente de las categorías de infección. Las más altas reducciones en el rendimiento de RN y RN3 debido a PVY fueron en el siguiente orden; PVY proveniente de semilla >>PVY por infección de campo >>no PVY.

“…Interestingly, when the cultivars used in this study that have been reported to produce mild symptoms when infected by PVY (Gem Russet [Love et al 2002], GemStar Russet [Love et al 2006], Russet Norkotah [Johansen et al 1988], Shepody [Sturz et al 1997]) were compared as a group over all years to the other 4 cultivars reported to (Radcliffe and Ragsdale 2002). Seed-borne PVY levels were higher in 2005 than in 2006 (Table 8) (Table 2).…”

“…All of the potato cultivars tested are susceptible to PVY (Johansen et al 1988;Love et al 2002;Love et al 2006;Mosley et al 2000;Novy et al 2003;Pavek et al 1992;Young et al 1983), but genetic differences amongst cultivars for virus acquisition, multiplication, and plant transport, specific host-vector-pathogen relationships, sensitivity of testing methods, and plant maturity may have influenced the differences recorded in infection levels. It is possible that infection rates were similar, but detection was hampered by reduced multiplication or transport within certain cultivars.…”

“…Thus, symptom development can further complicate the effort to control this virus, particularly in cultivars that produce mild or almost no symptoms such as Russet Norkotah (Johansen et al 1988), Shepody (Sturz et al 1997), Gem Russet (Love et al 2002), and GemStar Russet (Love et al 2006). In addition, though symptoms may be mild, yield losses in Russet Norkotah and Shepody can be significant Nolte et al 2004;Rykbost et al 1999).…”

Research plots were established in 2004, 2005, and 2006 at Hermiston, Oregon and in 2005 and 2006 in Othello, Washington to determine if potato cultivars differ in current season PVY infection. Eight potato cultivars were used; Gem Russet, GemStar Russet, Russet Norkotah, Shepody, Alturas, Ranger Russet, Umatilla Russet and Russet Burbank. The first four listed produce mild symptoms due to current season infection with PVY. Cultivars were planted in a randomized complete block design with four replications where each block contained a single 50-hill row for each cultivar. Leaf samples were evaluated monthly via ELISA to follow naturally occurring PVY infection. Cultivars that produce mild symptoms had higher current season infection levels. Over the 3 years at Hermiston, Shepody (93.8%), Gem (92.8%), Gemstar (89.8%) and Russet Norkotah (82.7%) had the highest infection levels, while Russet Burbank (68.8%), Umatilla Russet (58.0%), Ranger Russet (49.6%) and Alturas (48.1%) had the least infection. At Othello, infection levels were much lower and cultivar differences were minimal though Gem Russet had the highest current season infection (30.4%), Ranger Russet had the lowest (4.9%) and was significantly lower than Gem Russet and Shepody. Higher levels of infection occurred in 2006 at Hermiston and Othello (77.1% and 18.2%, respectively) compared to 2005 (66.7% and 10.2%, respectively). This is the first report where different cultivars of potatoes, growing side by side, had different levels of PVY infection. Possible explanations for differing current season infection levels between cultivars are discussed. Resumen Se establecieron lotes experimentales en 2004, 2005, y 2006 en Hermiston, Oregon, y en 2005 y 2006 enOthello, Washington, para determinar si variedades de papa difieren en un ciclo en infección por PVY. Se utilizaron ocho variedades; Gem Russet, GemStar Russet, Russet Norkotah, Shepody, Alturas, Ranger Russet, Umatilla Russet y Russet Burbank. Las primeras cuatro de la lista producen síntomas ligeros debido a la infección por PVY en el mismo ciclo de cultivo. Las variedades se plantaron en un diseño de bloques completos al azar con cuatro repeticiones, donde cada bloque contenía un surco sencillo de 50 plantas por variedad. Se evaluaron mensualmente muestras de hoja con ELISA para seguir la infección natural por PVY que se fuera presentando. Las variedades que producen síntomas ligeros tuvieron los niveles de infección más altos durante el ciclo. En los tres años en Hermiston, Shepody (93.8%), Gem (92.8%), Gemstar (89.8%) y Russet Norkotah (82.7%), tuvieron los niveles mas altos de infección, mientras que Russet Burbank (68.8%), Umatilla Russet (58.0%), Ranger Russet (49.6%) y Alturas (48.1%) tuvieron la infección mas baja. En Othello, los niveles de infección fueron mucho mas bajos y
