Analysis of sink/source relations in bread wheat recombinant inbred lines and commercial cultivars under a high yield potential environment
(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 ... -
Años requeridos para la evaluación a campo de cultivares comerciales de trigo pan en Argentina
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2022-09)En Argentina, la normativa vigente establece cuatro años de evaluación de rendimiento para cualquier nuevo cultivar comercial de trigo pan. El objetivo de este trabajo fue determinar la cantidad óptima de años de evaluación ... -
Early Selection for high spike fertility index in early generations increases grain number per unit area (and yield) of advanced breeding lines in bread wheat
(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 ... -
Effects of photoperiod sensitivity genes Ppd‐B1 and Ppd‐D1 on spike fertility and related traits in bread wheat
(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), ... -
Genome-wide association study for resistance in bread wheat (Triticum aestivum L.) to stripe rust (Puccinia striiformis f. sp. tritici) races in Argentina
(BioMed Central, 2022-11-24)Background: Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most devastating diseases of the wheat crop. It causes significant reductions in both grain yield and grain quality. In ... -
Increasing grain yield in bread wheat (Triticum aestivum) by selection for high spike fertility index
(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
(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
(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 ...
