Abstract
Analyses for secific gravity, total solids, total nitrogen, protein nitrogen, and nonprotein nitrogen are reported for 73 seedling samples grown in Maine, and for 10 selections grown in Idaho. The interactions between the various constituents, as indicated by regression analysis, are discussed. These samples indicate a potential for breeding a variety of potato with a higher than average protein content, but further work is necessary to determine the inheritance pattern. This work is in progress.
Resumen
Se reportan análisis para investigar gravedad específica, sólidos totales, nitrógeno de proteinas y nitrógeno de otros compuestos no proteínicos de 73 muestras de brotes crecidos en Maine y de 10 selecciones crecidas en Idaho. Se discuten las interacciones entre los varios constituyentes, como están indicadas por el análisis de regresión. Estas muestras indican un potencial de producir una variedad de papa con un contenido de proteina más alto que él promedio pero se necesita trabajo adicional para determinar el modo de herencia. Este trabajo está en progreso.
