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 ...
Assessment of cold tolerance at early developmental stages and allelic variation at candidate genes in South American rice germplasm Pachecoy, Maria Ines; Ramirez, Ignacio Abel; Marín, Alfredo; Pontaroli, Ana Clara (Springer, 2014-06)Rice is susceptible to cold during early developmental stages. Most tolerant cultivars have been developed for other conditions than those occurring in South America’s rice growing areas, or their grain type is not suitable ...
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), ...
Pontaroli, Ana Clara; Rogers, Rebekah L.; Qian, Zhang; Shields, Melanie E.; Davis, Thomas M.; Folta, Kevin M.; SanMiguel, Phillip; Bennetzen, Jeffrey L. (Crop Science Society of America, 2009-03)Thirty fosmids were randomly selected from a library of Fragaria vesca subsp. americana (cv. Pawtuckaway) DNA. These fosmid clones were individually sheared, and ∼4- to 5-kb fragments were subcloned. Subclones on a single ...
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 ...
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 ...
