Abstract
Neo-Tuberosum clones from the Cornell breeding population were evaluated as female parents in combination with Tuberosum for production from true seed. Field trials of hybrid seedling families were carried out in 1982 and 1983. Families were also grown in a hot greenhouse to measure combining abilities for tolerance to heat stress. General combining ability was highly significant for yield, vine and tuber characteristics, and heat tolerance. Several clones were identified which produced outstanding seedling families for yield, uniformity, and tuber appearance. Some individual crosses were equal to cultivars in yields, uniformity, and tuber appearance. Hybrids of Neo-Tuberosum and Tuberosum appear to be an excellent choice for potato production from true seed.
Resumen
Clones Neo-Tuberosum de poblaciones de mejoramiento de Cornell fueron evaluados como madres, en combinación con Tuberosum, para la producción de papa a través de semilla botánica. En 1982 y 1983, se llevaron a cabo ensayos de campo de familias de plántulas hibridas. También se cultivaron familias en un invernadero caliente para medir las capacidades combinadas para la tolerancia al estrés al calor. La capacidad general de combinación fue altamente significativa para el rendimiento, características del follaje y de los tubérculos, y la tolerancia al calor. Varios clones que produjeron sobresalientes familias de plántulas por su rendimiento, uniformidad, y apariencia de los tubérculos, fueron identificados. Algunas cruzas individuales fueron iguales a los cultivares en rendimiento, uniformidad, y apariencia de los tubérculos. Los híbridos de Neo-Tuberosum y Tuberosum parecen ser una alternativa excelente para producir papas a través de semilla botánica.
