Resumen
Las subpoblaciones de zapallo Cucurbita moschata Duchesne ex Poiret denominadas F7 y F7A, se obtuvieron después de dos ciclos de recombinación genética, selección, y evaluación en un ensayo de rendimiento, a partir de una población original compuesta por once familias promisorias destacadas por presentar características sobresalientes del fruto para el mercado en fresco y alto contenido de materia seca en el fruto (MS8%) en comparación con la variedad comercial UNAPAl Bolo verde (BV). La floración estaminada inicia a los 62.40 días±0.89 (F7) y 67.60±3.13 días (F7A), la floración pistilada a los 71.20±2.49días (F7) y 78.40±4.34días (F7A) después de la siembra en semilleros. Los frutos son de color amarillo, esféricos levemente achatados, completamente lisos o lisos con leve costilla, con peso promedio de 3.10 Kg± 0.73 (F7) y 3.60 Kg ± 0.54 (F7A) y superior en el contenido de materia seca a la variedad comercial BV (10.68%±2.08), F7 con 15.86%± 2.17 y F7A con 16.67%±1.63. El rendimiento promedio por planta bajo las condiciones del centro experimental de la Universidad Nacional de Colombia sede Palmira CEUNP (980 m.s.n.m) fue de16.21±5.62Kg/planta (F7) y 17.76±5.80Kg/planta (F7A) ligeramente mayor al expresado por el testigo comercial.
//Abstract. The squash subpopulatons Cucurbita moschata Duchesne ex Poiret called F7A and F7 were obtained after two cycles of genetic recombination, selection, and evaluation in a performance test, from an original population of eleven prominent families. Its fruits have important feartures for the fresh commercialization. Besides, high content of dry matter in the fruit (MS 8%) compared with a commercial variety UNAPAl Bolo Verde (BV). The stamina flowering starts in the 62.40 ± 0.89 days for (F7) and 67.60 ± 3.13 days for (F7A), and the pistils flowering starts in the 71.20 ± 2.49 days for (F7) and 78.40 ± 4.34 days for (F7A) after planting in seedbeds. The fruits are yellow, slightly flattened balls, completely flat and smooth with a slight rib, with average weight of 3.10 kg ± 0.73 for (F7) and 3.60 kg ± 0.54 for (F7A). The content of dry matter was 5.86 ± 2.17% for (F7) and 16.67% ± 1.63 for the (F7A). These values are higher than the commercial variety BV (10.68% ± 2.08. The average yield per plant under the conditions of the experimental site of the National University of Colombia Palmira CEUNP headquarters (980 m) was 16.21 ± 5.62 Kg/plant (F7) and 17.76 ± 5.80 Kg/plant (F7A) expressed slightly higher than commercial by the witness.
