Abstract
An interspecific hybrid ofS. phureja x USW1, a haploid of Katahdin, produced acceptable potato chips when processed directly from 40 F (4.5 C) storage during 3 years of testing. It was crossed with 11 interspecific hybrids. Tubers from these progenies were stored for 5 weeks at 40 F and then chipped immediately for 55 seconds in vegetable oil maintained at 375 F (190 C). Of 645 seedlings tested, chip color was acceptable in 17 and variable in 18. A group of 600 seedlings fromS. tuberosum parents treated comparably produced black-colored chips without exception.
Resumen
Un hibrido interspecifico deS. phureja x USW1 (haploide de la variedad Katahdin) produjo papas astilladas aceptables.
Estas papas fueron procesadas directamente de un almacen cuya temperatura fue mantenida a 4.5 C. Las pruebas fueron hechas durante tres años.
Este híbrido fue cruzado con once hybridos interespecificos. Tuberculos de estas progenies fueron almacenadas durante cinco semanas a 4.5 C y luego procesadas durante 55 segundos en aceite vegetal mantenido a 190 C. En una prueba de 645 plantas provenientes de estos cruces, se encontró que el color de las papas astilladas era aceptable en 17 clones y variable en 18 clones. Un grupo de plantas procesadas del mismo modo, pero proveninetes deT. tuberosum sin exepción produjeron papas astilladas de color negro.
