Combining ability in the function of inbreeding for yield and average fruit weight in Cucurbita moschata Duch. ex Poir.

In order to estimate the general and specific combining ability (GCA and SCA) in the function of inbreeding, three diallel crossings of butternut squash C. moschata Duch. ex Poir. were evaluated, each coming from six parents with three levels of inbreeding (S0, S1, S2). A two-stage nested design was...

description	In order to estimate the general and specific combining ability (GCA and SCA) in the function of inbreeding, three diallel crossings of butternut squash C. moschata Duch. ex Poir. were evaluated, each coming from six parents with three levels of inbreeding (S0, S1, S2). A two-stage nested design was used with four replicates. Yield per plant (YPP) and average fruit weight (AFW) were analyzed. In the So generation, only the GCA effects were important in the expression of YPP and AFW. In the first generation of inbreeding (S1), both the GCA and SCA effects were important in the genetic control of YPP and AFW. In the second generation of inbreeding (S2), both the GCA and SCA effects were again significant in the expression of AFW. The UNAPAL-Dorado (S0 parent) and UNAPAL-Abanico-75-1 × UNAPAL-Llanogrande-2 (hybrid of S2 inbred lines) are the most indicated genotypes for improving the AFW with intra-population recurrent and reciprocal recurrent selection, respectively, with the target market of fresh consumption by consumers who prefer to buy whole fruits and not sliced fruits. Similarly, the recommended genotypes for improving the AFW for the fresh consumption market and for agro-industrial use by consumers, for whom the weight of the fruit is not a limiting trait for acquisition, include UNAPAL-Abanico- 75-2 (S2 inbred line) with intra-population recurrent selection, UNAPAL-Abanico-75-1 × UNAPAL-Llanogrande- 1 (hybrid of S1 inbred lines) and UNAPAL-Abanico-75-1 × UNAPAL-Dorado (hybrid of S2 inbred lines), both with reciprocal recurrent selection.

SB320-353.5 In order to estimate the general and specific combining ability (GCA and SCA) in the function of inbreeding, three diallel crossings of butternut squash C. moschata Duch. ex Poir. were evaluated, each coming from six parents with three levels of inbreeding (S0, S1, S2). A two-stage nested design was used with four replicates. Yield per plant (YPP) and average fruit weight (AFW) were analyzed. In the So generation, only the GCA effects were important in the expression of YPP and AFW.

The UNAPAL-Dorado (S0 parent) and UNAPAL-Abanico-75-1 × UNAPAL-Llanogrande-2 (hybrid of S2 inbred lines) are the most indicated genotypes for improving the AFW with intra-population recurrent and reciprocal recurrent selection, respectively, with the target market of fresh consumption by consumers who prefer to buy whole fruits and not sliced fruits.

Para estimar las habilidades combinatorias general (HCG) y específica (HCE) en función de la endogamia, se evaluaron tres cruzamientos dialélicos de zapallo C. moschata Duch. ex Poir., constituidos cada uno por seis progenitores con tres niveles de endogamia (S0, S1 y S2). Se utilizó un diseño anidado de dos etapas con cuatro repeticiones. Se analizaron las variables producción de frutos por planta (PFP) y peso promedio del fruto (PPF). En el nivel de endogamia S0, solamente la HCG fue importante en la expresión de PFP y PPF. En el nivel de endogamia S1, la HCG y HCE fueron importantes en el control genético de PFP y PPF. En el nivel de endogamia S2, la HCG y HCE fueron importantes en la expresión de PPF. Los genotipos más indicados para mejorar PPF con destino al mercado de consumo en fresco, constituido por consumidores que prefieren frutos enteros y no en rodajas, son el progenitor S0 UNAPAL-Dorado (por selección recurrente intrapoblacional) y el híbrido entre líneas endogámicas S2 UNAPAL-Abanico-75-1 × UNAPAL-Llanogrande-2 (por selección recurrente recíproca). Igualmente, los genotipos recomendados para mejorar PPF para el mercado de consumo en fresco o uso agroindustrial, conformado por consumidores en los cuales el PPF no es una característica limitante para su adquisición, son la línea endogámica S2 de UNAPAL-Abanico-75-2 (por selección recurrente intrapoblacional), el híbrido entre líneas endogámicas S1 UNAPAL-Abanico-75-1 × UNAPAL-Llanogrande-1 y el híbrido entre líneas endogámicas S2 UNAPAL-Abanico-75-1 × UNAPAL-Dorado (por selección recurrente recíproca).
