Analysis of sink/source relations in bread wheat recombinant inbred lines and commercial cultivars under a high yield potential environment
Alonso, Maria Pía; Abbate, Pablo Eduardo; Mirabella, Nadia Estefania; Aramburu Merlos, Fernando; Panelo, J.S.; Pontaroli, Ana Clara (2018-02)Grain yield in wheat is generally considered to be sink-limited during grain filling. But is this limitation inherent to the crop species or a consequence of the breeding process? A way to ascertain this is by using genetic ... -
Identificación y validación de variables asociadas con la susceptibilidad al vuelco en trigo pan en el sudeste bonaerense.
Mirabella, Nadia Estefania (2016-03)El vuelco es la pérdida de la posición vertical normal de los tallos y uno de los obstáculos para el alcance del rendimiento potencial en trigo pan, por lo que es necesario generar variedades de buen comportamiento. En ... -
Increasing grain yield in bread wheat (Triticum aestivum) by selection for high spike fertility index
Pontaroli, Ana Clara; Alonso, Maria Pía; Mirabella, Nadia Estefania; Panelo, Juan Sebastián; Franco, Maria Fiorella; Vanzetti, Leonardo Sebastian; Lorenzo, Maximo (Wiley, 2021-06-28)Spike fertility index (SF) has been proposed as a promising selection criterion for increasing grain yield (GY) in bread wheat. Here, changes in GY and related traits after simulated selection (10% intensity) for high SF ... -
Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat
Alonso, Maria Pía; Mirabella, Nadia. E; Panelo, Juan Sebastián; Cendoya, Maria Gabriela; Pontaroli, Ana Clara (Springer Netherlands, 2018-07-18)Spike fertility index (SF) has been proposed as a promising trait to be used as a selection criterion in wheat breeding programs aimed at increasing grain yield, but no actual evidence of its successful application has ... -
Spike architecture traits associated with type II resistance to fusarium head blight in bread wheat
Franco, Maria Fiorella; Lori, G.; Cendoya, Maria Gabriela; Alonso, Maria Pía; Panelo, Juan Sebastián; Malbrán, I.; Mirabella, Nadia Estefania; Pontaroli, Ana Clara (Springer, 2021-11-05)Fusarium head blight (FHB) remains a devastating disease in bread wheat (Triticum aestivum L.). Genetic resistance to FHB is complex; aside from active physiological resistance, plant developmental and morphological traits ... -
Wheat spike fertility : inheritance and relationship with spike yield components in early generations
Martino, Diana Laura; Abbate, Pablo Eduardo; Cendoya, Maria Gabriela; Gutheim, Florencia; Mirabella, Nadia Estefania; Pontaroli, Ana Clara (2015)In wheat, grain number is considered as the product of spike dry weight (SDW) and the number of grains per unit of SDW, that is an indicator of spike fertility (SF). The aim of this study was to determine the heritability ...
