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 ... -
Bases moleculares de la fertilidad de la espiga en trigo pan
Alonso, Maria Pía (Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2018-03)El trigo pan es uno de los cultivos de granos más importantes del mundo. Uno de los principales objetivos del mejoramiento genético a nivel mundial es el aumento del rendimiento en grano. El rendimiento es un carácter ... -
Early selection for spike fertility index increases yield of advanced generations in bread wheat
Alonso, María Pía; Franco, María Fiorella; Pontaroli, Ana Clara (Wiley, 2023-03)Spike fertility index (a.k.a. fruiting efficiency) at maturity (FEm -grain number per spike/g spike chaff at maturity-) and spike harvest index (SHI -grain weight per spike/g spike chaff weight at maturity-) are considered ... -
Eficiencia de fructificación en madurez en trigo pan
Alonso, Maria Pía; Franco, Maria Fiorella; Pontaroli, Ana Clara (Estación Experimental Agropecuaria Balcarce, INTA, 2021-11)Su uso en un programa de mejoramiento como carácter de selección para incrementar el número de granos/m2 -
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 ... -
The physiology and genetics behind fruiting efficiency, a promising spike trait to improve wheat yield potential
Pretini, Nicole; Alonso, Maria Pía; Vanzetti, Leonardo Sebastian; Pontaroli, Ana Clara; Gonzalez, Fernanda Gabriela (Oxford University Press, 2021-03)The fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination (the ...
