Abstract
Field trials were conducted at Freeville, NY to determine if hybrid seedling populations ofSolanum tuberosum L. could be improved by two types of mass selection. Hill and bulk selections plus unselected controls were saved after harvesting tubers from transplanted seedlings of four Neo-Tuberosum × Tuberosum hybrids in 1982. Tubers from these three treatments were planted in a split plot design for comparison in 1983. Yields were increased 14 to 16% by hill selection; plants from this treatment were the largest and most vigorous. Uniformity of tuber shape and overall tuber appearance were improved by both hill and bulk selection.
Resumen
Fueron conducidos ensayos de campo en Freeville, NY, para determinar si las poblaciones de plántulas híbridas deSolanum tuberosum L. podrían ser mejoradas a través de dos tipos de selección masal. En 1982, se reservaron selecciones por mata o punto de siembra y selecciones globales o al granel, más testigos no seleccionados, después de cosechar los tubérculos de plántulas transplantadas de cuatro híbridos Neo-Tuberosum × Tuberosum.
En 1983, los tubérculos procedentes de estos tres tratamientos fueron sembrados en un diseño de parcelas divididas para su comparación. Los rendimientos se incrementaron 14 a 16% por mata seleccionada; las plantas de este tratamiento fueron las más grandes y vigorosas. La uniformidad de la forma y de la apariencia general de los tubérculos fue mejorada tanto por la selección por mata como por las selección global.
