“…From our results, it is obvious that the cultivar with high plasticity should provide, in years unfavorable for achieving a high spike number, sufficient compensation by increasing the spike productivity. Similarly García del Moral et al (2003) showed that yield stability of barley cultivars under different environments is closely associated with the number of grains per spike ensuring the achievement of a high number of grains per area unit also under the conditions of lower spike number.…”

Timely and reliable prediction of grain yield and quality of spring barley represents a key prerequisite for effective crop management. Within this study we evaluated the relationships between yield components, grain quality, biomass production and the number of tillers in different growth stages. For this purpose, in three years (2011)(2012)(2013) multifactorial field trials focused on the combined effects of cultivar, sowing density and nitrogen nutrition were conducted. Based on ANOVA it was found that the formation of grain yield was affected by individual factors in the following order of importance: year, nitrogen, cultivar and sowing rate. The final grain yield significantly correlated both with the number of tillers and dry weight of above-ground biomass per unit area. The best estimation of yield provided both parameters at early growth stage (R = 0.83** and 0.81** for number of tillers and the above-ground biomass at BBCH 25). The grain protein content was inversely related to early growth parameters (R = -0.64** and -0.41** for number of tillers and above-ground biomass at BBCH 25). Based on the comparison of relationships between the years, it can be concluded that the early growth of barley and tiller differentiation is a key parameter for the formation of yield and grain quality.

“…Posle formiranja broja klasova i broja zrna po klasu tokom vegetativne faze, prinos postaje uglavnom određen masom zrna (Wiegand and Cuellar, 1981). Prema navodima Garcia del Moral et al (2003), stabilnost prinosa pod uticajem različitih uslova sredine usko je povezan sa brojem zrna po klasu, jer veliki broj zrna u klasu omogućava postizanje velikog broja zrna po jedinici površine i u uslovima manjeg broja klasova.…”

A field trial was conducted on an acid pseudogley soil during the 2011/12, 2012/13 and 2013/14 growing seasons to evaluate grain yield and its components in four triticale cultivars ('Favorit', 'Tango',. The highest values of grain yield, 1,000-grain weight, number of grains per spike, spike length and plant height in all cultivars were obtained in the year characterised by moderate temperatures during grain filling and high amounts of rainfall in the second part of the growing season. 'Favorit' gave the highest grain yield, the largest number of grains per spike, the lowest 1,000-grain weight and the smallest plant height. The highest 1,000-grain weight and the lowest number of grains per spike were found in 'Tango'. 'KG-20' had the greatest plant height and the lowest average grain yield during the three experimental years, with the lowest grain yield achieved in the driest year, and the highest in the wettest year. 'Odisej' exhibited a high grain yield, fewer grains per spike, and the lowest grain weight per spike compared to the other cultivars.

“…In addition to yield potential, yield stability (the selection of genotypes with more stable performance) remains a key objective for crop breeders (Slafer and Kernich, 1996). Becker and Leon (1988) believe that a successful genotype should produce consistently high yields over a wide range of environmental conditions, with a concomitant increase in stress tolerance (Tollenaar and Lee, 2002), such as drought stress (del Moral et al, 2003). There is evidence that modern cultivars with higher yields respond better to environmental change and have greater yield potential but less yield stability than older cultivars (Siddique et al, 1989a,b; Loss and Siddique, 1994; Fufa et al, 2005; Acreche et al, 2008).…”

Moderate Drought Stress Affected Root Growth and Grain Yield in Old, Modern and Newly Released Cultivars of Winter Wheat

et al. 2017

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes under moderate drought (MD, 55% of field capacity) or well-watered (WW, 85% of field capacity) conditions. In the field trial, plots were either rainfed (moderate drought stress) or irrigated with 30 mm of water at each of stem elongation, booting and anthesis stages (irrigated). Compared to drought stress, grain yields increased under sufficient water supply in all cultivars, particular the newly released cultivar CH1 with 70% increase in the nursery and 23% in the field. When well-watered (nursery) or irrigated (field), CH1 had the highest grain yields compared to the other two cultivars, but produced similar yield to the modern cultivar (CH58) under water-stressed (nursery) or rainfed (field) conditions. When exposed to drought stress, CW134 had the highest topsoil root dry mass in topsoil but lowest in subsoil among the cultivars at stem elongation, anthesis, and maturity, respectively; while CH1 had the lowest topsoil and highest subsoil root dry mass at respective sampling times. Topsoil root mass and root length density were negatively correlated with grain yield for the two water treatments in nursery experiment. When water was limited, subsoil root mass was positively correlated with thousand kernel weight (TKW). In the field trial, CH1 and CH58 used less water during vegetative growth than CW134, but after anthesis stage, CH1 used more water than the other two cultivars, especially in the soil profile below 100 cm, which was associated with the increased TKW. This study demonstrated that greater root mass and root length density in subsoil layers, with enhanced access to subsoil water after anthesis, contribute to high grain yield when soil water is scarce.
