juanita norte

[TZ-OH6]

Tom? anybody? Can I get a basic description of Juanita Norte (white? yellow? red?. I could find nothing googling it... lots of hits for Juanita and Norte, but none having to do with taters. It is one of my better growing plants and since I have my mad scientist hat on I may want to cross it with something.

Juanita Norte is a brand new variety created last year from the cross of
Juan Valdez and Norte Azul July 28, 2005. It was a strong seedling, the best of nine that had the number 6531309. It started out life in a raised bed in Lake City. Lake City is the northeast corner of Seattle, centered along Lake City Way.

I sent this clone out because of the vigor and Late blight reisistance, coming nearly all form the Juan Valdez clone. Juan Valdez was a first year seedling tuber planted near Conway, WA June 2004. The female parent was Juanita, a red potato from Mexico that has good blight resistance. Juanita is a cross of LOMAN x ANITA.

The male parent of Juan Valdez is B0767-2, an experimental clone that had good blight resistance in the past. Here is a quote about it...

June 1997 Abstract Two potato breeding selections were released by the United States Department of Agriculture, Agricultural Research Service on November 14, 1996, as germplasm that is highly resistant to current populations ofPhytophthora infestans (Mont.) deBary, the causal organism of potato late blight: B0718-3 and B0767-2. These two clones have been evaluated for their reaction toP. infestans in replicated plots at Presque Isle, Maine since 1990. B0718-3 is a netted white-skinned selection with good yields but low specific gravity. It is both male and female fertile and crosses readily with tetraploid Tuberosum. B0767-2 is a russet-skinned selection that is low yielding and low in specific gravity. It has not been successfully crossed; however, it may have some potential use in somatic hybridizations. Neither B0718-3 nor B0767-2 process into acceptable colored chips. Genetic material of this release has been deposited in the National Plant Germplasm System where it is available for research purposes, including development and commercialization of new cultivars.

Juan Valdez had great blight resistance in Skagit County for several years. It was a light pink potato with a slightly russeted skin. It had a large canopy and a heavy stem. The flavor was acceptable with very pale yellow flesh.

The male parent of Juanita Norte was Norte Azul. Norte Azul was a first year seedling in 2005 and was a vigorous blue potato with slighly blue flesh. Norte Azul has pink rot resistance from the mother Nordic October and blue skin and flesh from Azul Toro. Nordic October is a cross made in 1998 between NorDonna and Red October. Azul Toro is a cross between Negro y Azul and Kern Toro.

The cross (Juanita Norte) was named honoring the parental direction of the cross and to indicate that here was a Juanita type adapted to the North. It has red skin, and slightly red flesh. It is outstanding for blight resistance and vigor.

Now you can Google Juanita Norte...

Sounds good. Some of my blues aren't looking so hot so this one will be useful.
