“…Miller et al (2004) showed that RN3's had an average plant height of 65.0 cm compared to RN height of 61.0 cm, 68 days after planting. Texas selections of RN also show a later maturity rating when compared to the standard RN (Miller et al 1999). In Springlake, TX, a commercial growing area with a similar number of growing days compared to Hermiston, OR, the maturity rating for standard RN was 4.0 and the average for 13 RN selections was 2.9 (scale 1=very late, 5=very early).…”

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.

“…In 1989, improved RN line selection programs were initiated in Texas (Miller et al 1999) and Colorado. The clonal selections that emerged from those efforts had increased vine vigor, some resistance to early dying (associated with Verticillium dahliae) and out-yielded the standard RN by 20-30%.…”

“…Given sufficient time these features may become apparent in normal populations. For example, certain Russet Norkotah strains exhibit a strong locale-based superiority when selected for giant hill features (Miller et al 1999). Certainly the selection of new potato strains from "bolters" or "giant hills" (Leever et al 1994) has been repeatedly successful for the improvement of vigor, yield, maturation or disease resistance in Norgold Russet, Russet Norkotah, Superior and Red La Soda cultivars (Miller 1954;Leever et al 1994;Miller et al 1995Miller et al , 1999.…”

Since the Russet Burbank strains previously examined did not exhibit the visible traits of giant hills (e.g., late maturity, greater vigor) and appear to have arisen through local selection pressures, they could be considered as possible geographical clones (Leever et al 1994).…”

S. 2003. Chemical maturation and storage performance of eleven Russet Burbank clones. Can. J. Plant Sci. 83: 893-902. Although introduced as a cultivar from a somaclonal mutation of smooth Burbank in the 19th century, the subsequent identification and commercial selection of distinct Russet Burbank clones or strains has not been evident in the scientific literature. The present study examined chemical maturity of tubers (sucrose rating values and glucose content) and subsequent storage performance over a 3-yr period (1999)(2000)(2001) of eleven Russet Burbank clones collected from across North America in order to determine if subtle quality traits could be associated consistently with specific clones. Although considered a late maturity cultivar (140 d), all clones were chemically mature (sucrose rating values of approximately 1) at the New Brunswick growing site by 125 d. Exploratory cluster analyses using hierarchical or nonhierarchical methods applied to pre-harvest and harvest sucrose and glucose levels in tubers during the 3-yr study allowed the North American clones to be separated into clusters that reflected geographical biases and this hypothesis was supported by canonical discriminant analysis. Exploratory cluster analysis of post-harvest data, however, did not find any consistent structure in the clones based on sucrose or glucose levels during storage at 4 or 10°C for up to 8 mo or after reconditioning from 4°C. Polymerase chain reaction analysis of 10 selected simple sequence repeat (SSR) regions confirmed that the 11 clones belonged to the cultivar Russet Burbank. The limited geographically featured clustering based on pre-harvest sugar changes observed among the clones may have their origins in cultural practices with somaclonal variation leading to geographical strains of the cultivar. Bien que le cultivar Russet Burbank résulte d'une mutation somaclonale de la Burbank lisse survenue au XIX e siècle, la littérature scientifique a relativement fait peu de cas des clones ou des souches identifiés ou sélectionnés par la suite pour le commerce. L'étude de trois ans dont il est question ici portait sur la maturité chimique (indice de sucrose et teneur en glucose) et les aptitudes à l'entreposage des tubercules de onze clones de Russet Burbank prélevés un peu partout en Amérique du Nord. Elle devait établir s'il est possible d'associer de manière cohérente de légères variations de qualité à tel ou tel clone. Bien que théoriquement de maturité tardive (140 jours), au site expérimental du Nouveau-Brunswick, les clones avaient atteint la maturité chimique (indice de sucrose à peu près égal à 1) au bout de 125 jours. Les analyses préliminaires par grappes, hiérarchisées ou non selon la concentration de sucrose et de glucose avant la récolte et au moment de celle-ci, effectuées au cours des trois années de l'étude ont permis de séparer les clones nord-américains en groupes présentant un biais géographique, hypothèse qu'est venue confirmer l'analyse par discrimination canonique. L'analyse par grappes prélim...
