Abstract
A field trial was conducted at Freeville, NY to compare yields from hybrid families ofSolanum tuberosum L. with yields from their corresponding full sib, first clonal generation tubers. Unselected tubers were saved after harvesting transplanted seedlings of four Neo-Tuberosum × Tuberosum hybrids in 1982. The following year these tubers were planted for comparison with seedlings of the same hybrids in a split plot design. Total yields and yields of tubers ≥ 38 mm in diameter were respectively 34% and 38% higher from tuber propagated plants than from seedlings. The biggest difference was in tubers ≥ 63 mm diameter, where plants from tubers gave yields more than double those from seedlings. Seedlings had twice as many large axillary branches per stem as plants from tubers. Uniformity of tuber size and shape, and overall appearance ratings of tubers were better with seedling propagation; however, these comparisons are biased by the tendency of seedlings to produce smaller tubers, which inherently receive higher ratings.
Resumen
Un ensayo de campo fue conducido en Freeville, NY, para comparar los rendimientos de familias de plántulas híbridas deSolanum tuberosum L. con los rendimientos de las correspondientes progenies de los tubérculos de la primera generación clonal.
En 1982, se reservaron tubérculos, no seleccionados, después de la cosecha de las plántulas transplantadas de cuatro híbridos Neo-Tuberosum x Tuberosum.
Estos tubérculos fueron sembrados al año siguiente para ser comparados con plántulas de los mismos híbridos, en un diseno de parcelas divididas. Los rendimientos totales y aquellos de tubérculos de diámetro ≥ 38 mm fueron respectivamente 34% y 38% mayores en las plantas propagadas por tubérculos que en aquellas propagadas mediante plántulas.
La mayor diferencia fue la obtenida con tubérculos de ≥ 63 mm, encontrándose que las plantas procedentes de tubérculos rindieron más del doble de tubérculos de este tamano que aquellas procedentes de plántulas.
Las plántulas tuvieron el doble de ramas axilares largas por tallo que el plantas procedentes de tubérculos. La uniformidad del tamaño y de la forma de los tubérculos, y las apreciaciones de la apariencia general de los tubérculos, fueron mejores en la propagación por plántulas; sin embargo, estas comparaciones fueron influenciadas por la tendencia de las plántulas a producir tubérculos más pequenos, los cuales inherentemente reciben calificaciones más altas.
