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 ... -
Efecto de la fertilización nitrogenada en soja intersembrada en trigo en Balcarce
Carpaneto, Barbara Bettina; Lorenzo, Maximo; Abbate, Pablo Eduardo (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)Es sabido que la soja intersembrada en trigo tiene bajo crecimiento inicial, lo cual podría afectar negativamente la formación de nódulos fijadores de nitrógeno (N) y limitar el crecimiento de la soja luego de la cosecha ... -
Effects of photoperiod sensitivity genes Ppd‐B1 and Ppd‐D1 on spike fertility and related traits in bread wheat
Ramirez, Ignacio Abel; Abbate, Pablo Eduardo; Redi, Ignacio W.; Pontaroli, Ana Clara (Wiley Online Library, 2018-04-27)Increasing grain yield is a key breeding goal in bread wheat. Several authors have suggested that a spike fertility index (SF), that is the quotient between grain number per unit spike (GNS) and spikechaff dry weight (SCDW), ... -
Frost damage on grain number in wheat at different spike developmental stages and its modeling
Martino, Diana Laura; Abbate, Pablo Eduardo (Elsevier, 2019-02)Frosts may damage wheat (Triticum aestivum L.) spikes and severely reduce their yield. The objective of this study was (i) to quantify the level of susceptibility to frost at different spike developmental stages, and (ii) ... -
Variation in reproductive frost susceptibility of wheat cultivars is not associated with variation in glume and lemma thickness
Martino, Diana Laura; Abbate, Pablo Eduardo; Biddulph Ben, Thomas; Pontaroli, Ana Clara; Marcovich, Norma (Elsevier, 2020-11-05)The thickness of wheat (Triticum aestivum L.) glumes and lemmas (TGL) influences their thermal insulation properties, which in turn, may influence reproductive frost susceptibility. The objectives of this study were to (i) ... -
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 ...
