“…In cereals, grain number per unit area and grain weight represent two major grain yield components (Cossani et al 2011). Although grain yield of major cereal crops is more correlated with grain number per unit area (Peltonen-Sainio et al 2007), high and stable yields are often positively associated with increased grain weight (Pržulj et al 2012;Sun et al 2017). Grain weight is defined by two major parameters: rate and duration of grain filling.…”

Knowledge about the comparative development and grain filling of winter cereals under different environmental conditions is important for stable and high yielding crop production. The objective of this work was to compare patterns of grain filling in bread wheat, barley and triticale grown in the Pannonian region, as well as to investigate relationships among grain filling parameters, time to anthesis and grain yield. The trials with 12 winter cereal genotypes were carried out in four successive seasons at the location Novi Sad, Serbia. Results of this study showed that all studied grain filling parameters were significantly influenced by species, cultivar, growing season, and species by growing season interaction. Longer duration of grain filling period and period to maximum grain filling were observed in triticale and wheat cultivars compared with six and two-rowed barley. Two-rowed barley cultivars had a higher grain filling rate than other cultivars. Furthermore, a negative association between time to anthesis and grain yield indicates that cultivars with the long preanthesis period are not recommended for the agro-ecological conditions of the Pannonian plain. Generally, medium early cultivars of small grain cereals had the highest grain weight within species and spike type, suggesting that medium early cultivars have a balanced ratio of pre-anthesis and grain filling period. High values of final grain weight in different growing seasons indicate that weather conditions in the Pannonian plain are mainly suitable for grain growth.

“…Ayerza y Coates (2009a) mencionan que el contenido de proteína en chía es influenciado por el ambiente. En trigo, el mayor rendimiento se logra con mayor peso de grano, lo que valdría la pena considerar en la selección de cultivares de chía (Sun et al, 2017).…”

La chía es un recurso muy valioso ya que es la principal fuente de ácidos grasos insaturados, principalmente α-linolénico, además de proteína y fibra. En esta investigación se realizaron siete colectas en siete localidades para su estudio y comparación. Se midió tamaño de semilla, peso de mil semillas, peso volumétrico, color, porcentaje de germinación y extracción de aceite para análisis en cromatografía. La colecta de chía cultivada de Guanajuato presentó mayor variabilidad en tamaño de semilla y la de Roque la menor. Las colectas silvestres tuvieron el menor tamaño de semilla. La cultivada de Guanajuato tiene el peso mayor en semilla y las silvestres el menor, estas últimas no germinaron, pero sí lo hicieron las domesticadas. No hubo diferencias en peso volumétrico; sin embargo, si hubo diferencias en los cromatogramas (HPLC) y en las características físicas y variación de color en las domesticadas, incluidas semillas de color blanco. Esta investigación prospectiva muestra que la variabilidad presente en la chía silvestre y cultivada puede ser aprovechada para el fitomejoramiento.

“…However, small grain cereals differ significantly in grain number per unit area and grain yield determination (Mirosavljević et al, 2018), since two-rowed winter barley grain number variation is more related to spike number per unit area, while in wheat, grain number is associated with both grain number per spike and spike number per unit area (Prado et al, 2017). Also, grain yield in cereal crops is related to an average grain weight, especially under less favourable environmental conditions (Lizana, Calderini, 2013;Sun et al, 2017).…”

The objectives of this study were to quantify the grain yield breeding progress and identify the changes in numerical yield components and grain filling traits of six-rowed winter barley (Hordeum vulgare L.) cultivars under different nitrogen (N) fertilization treatments: 0 kg ha-1 N (0N, control) and 100 kg ha-1 N (100N). Field trials were conducted during two (2015-2016 and 2016-2017) growing seasons in a southern Pannonian location, Novi Sad, Serbia with fifteen six-rowed winter barley cultivars. The rate of genetic gain in grain yield was 0.055 t ha-1 yr-1 at 0N, while at 100N genetic gain was 0.061 t ha-1 yr-1 , indicating that modern winter barley cultivars use the applied N fertilizer more efficiently than older cultivars. Grain yield progress was mainly associated with increased grain number per unit area, grain number per spike, grain weight and harvest index. A positive linear correlation was determined between fruiting efficiency and the year of cultivar release, while changes in spike dry weight at anthesis as influenced by the year of cultivar release were not significant. Breeding progress in grain weight was more related with grain filling and maximum grain filling rate, while grain weight association with grain filling duration was less pronounced. Therefore, further grain yield improvement in six-rowed winter barley should be achieved by simultaneous increase in grain weight and grain number per spike, while maintaining high values of harvest index.
