“…thermal and rainfall factors, influence crop plants growth and development, causing quantitative modifications of plants morphological structure, durations of developmental phases and yield-forming factors levels, which determine grain yield per spike and per plant are presented widely in literature (Gut et al, 1996;Kaur and Behl, 2010;Porter and Gawith, 1999;Barnabás et. al., 2008;Modarresi et al, 2010;Orzech et al, 2009;Rahman et al, 2009;Rajala et al, 2009;Spiertz et al, 2006;Ugarte et al, 2007;Balla et al, 2012, Golba et al, 2013, Talukder et al, 2013. Our results presented in this publication, concerning the impact of variable weather conditions on plant or spike morphological structure, yield-forming factors level as an equivalent to yield components and grain yield per spike and per plant, showed similarities with literature data presented above.…”

“…Literature data indicates that temperature increase (heat stress) leads to reduction of grain yield resulting in a smaller number of individuals and different yield-forming factors taking into account by researchers (Balla et al, 2012;Rahman et al, 2009;Modarresi et al, 2010;Spiertz et al, 2006;Ugarte et al, 2007;Sharma et. al., 2008;Hossain et al, 2013, Talukder et al, 2013.…”

The yield-forming potential of winter wheat is determined by several factors, namely total number of shoots per plant and total number of spikelets per spike. The field experiments were conducted during three vegetation seasons at the Plant Breeding and Acclimatization Institute -National Research Institute (PBAI-NRI), located in Radzików, Poland. The objective of this study was a comparative analysis of the structural yield-forming factor levels, which determine grain yield per spike and per plant of the DH lines and standard Izolda cultivar. Results indicate that several DH lines showed some differences in tested morphological structures of plant, yield factor levels and in grain yield per spike and per plant in comparison to standard Izolda, regardless of the year. Mean grain yield per plant of DH lines was 26.5% lower in comparison to standard Izolda only in the second year of study. It was caused by a reduction of productive tillers number. Structural yield-forming potential of DH lines was used in 38% and 59% and in case of Izolda in 47% and 61% (the second and the third year of experiment, respectively). The mean grain yield per spike of DH lines was 14.8% lower than Izolda cultivar only in third year of experiment and it was caused by about 12% lower number of grains per spike. Structural yield-forming potential of DH spikes was used in 82.4%, 85.4% and 84.9% and in case of Izolda in 83.8%, 87% and 89.5% (the first, the second and the third year of experiment, respectively). The grain yield per winter wheat plant (both DH lines and standard Izolda) was significantly correlated with the number of productive tillers per plant (r = 0.80). The grain yield per winter wheat spike (both DH lines and Izolda cultivar) was significantly and highly correlated with the number of grains per spike (r = 0.96), number of fertile spikelets per spike (r = 0.87) and the spike length (r = 0.80). Variation of spike and plant structural yield-forming factors determining grain yield levels were also analyzed. Calculated total variation coefficients values of each analyzed trait during three-year long studies were different depending on plant material -DH lines or standard Izolda. Low variation coefficients values characterized following traits (traits ranked by increasing values for DH lines and standard Izolda, respectively): total spikelets number per spike (6.6 and 6.3%), spike length (11.1 and 12.6%), fertile spikelets number per spike (13.7 and 11.7%)

“…In the present study, heat treatment was carried out at five different phenological phases, from the first node detectable (DEV31) growth stage to 20 days after flowering, on four wheat genotypes with very different adaptation strategies, representing the pair wise parental lines of two wheat mapping populations (Balla et al 2012).…”

“…Many studies have reported that high temperatures cause an array of morpho-anatomical, physiological, biochemical, molecular and cellular changes in plants (Wahid et al 2007;Barnabás et al 2008;Almeselmani et al 2012). There is increasing evidence on the significant negative effects of heat stress on yield and yield components during the generative phases (Farooq et al 2011;Semenov and Shewry 2011;Balla et al 2012). Elevated temperature induces pollen sterility and seed abortion, resulting in lower seed weight, and also significantly affects flour yield and dough quality (Hays et al 2007;Altenbach 2012).…”

In the present study, heat treatment was carried out in five different phenological phases, from the first node detectable (DEV31) growth stage to 20 days after flowering, on four wheat genotypes with very different adaptation strategies. They were grown in a controlled environment in a phytotron chamber and exposed to a night temperature of 20ºC and a day temperature of either 30ºC, at DEV31, or 35ºC at all the later developmental phases, for an interval of 14 days. Plant height, leaf number, number of tillers, grain number and grain weight per main and side spikes, TKW per main and side spikes, length of the main and side spikes, and spikelet number per main and side spikes were recorded. High temperature enhanced the stem growth intensity, plant height and tiller number. In contrast, the length of side spikes, spikelet no./side spike, grain no./main and side spike, grain weight/main and side spike and TKW/main and side spike were significantly decreased. The stress response depended strongly on the developmental phase in which the heat stress was applied. Fleischmann 481 and Soissons showed definitely contrasting tendencies both in grain number and grain weight. In the case of the Plainsman V and Mv Magma pair, the higher heat stress tolerance of Magma compared to Plainsman V was evident also from the grain number and weight of the main spike at each developmental phase.

“…Budak et al (2013) agreed that utilization of drought tolerant wild species and the rapid advances in molecular, biological, functional genomics, and transgenic technologies have facilitated drought-related studies. However, using physiological screening and the measurement of yield components under stress condition is still the most effective way of identifying stress-tolerant wheat lines (Balla et al 2012). The most popular approach to breeding until now has been to select for plants with highest yield in field trials across the production zone (Tardieu and Hammer 2012).…”

An important objective of wheat improvement programmes is to breed varieties for high yield in optimum conditions and for minimum yield reduction under stress-prone conditions such as heat and drought. Analyses of yield and its components in multiple years allow a comprehensive and comparative understanding of genetic yield potential and stress-tolerance mechanisms in the study germplasm. The present study was carried out to evaluate performance of elite varieties and landraces of spring durum wheat under different water regimes, determine the repeatability of the examined traits, and identify superior genotypes for their potential use in breeding for drought tolerance. A total of 97 accessions of spring durum wheat (T. durum Desf.) were evaluated under rain-fed and well-watered conditions in the nursery of the Centre for Agricultural Research at Martonvásár, Hungary (2011. The experiments were laid out in an unbalanced, incomplete alpha lattice block design. The trait with the lowest broad-sense repeatability was seed length (0.075), while high h 2 values were observed for heading date (0.89), thousand-grain weight (0.85) and the protein content (0.85). Grain yield showed moderate level of repeatability (0.53) across the three years. The principal component analysis revealed that grain yield (t/ha) is positively associated with the fertile tiller number, chlorophyll content values at early waxy ripeness stages and plant height. Based on biplot analysis, 'DP-133′, 'DP-017′ and 'DP-061′ proved to be the best durum cultivars in terms of yield whereas genotypes 'DP-011′, 'DP-185′, 'DP-126′ and 'DP-136′ preceded them with their good yield stability.
