“…Besides the dwarf habitus, the rise in HI values was associated with the highest number of kernels per square metre, while other parameters such as number of spikelets per spike and spike length, did not show a clear trend in relation to breeding improvements. The HI values observed in the present study were lower than those commonly obtained for durum wheat grown under conventional (high N input) farming, but aligned with values reported for low nitrogen input management (De Vita et al, 2007b;Giunta et al, 2007). All the investigated durum wheat varieties investigated presented test weight values lower than market requests (>80 kg/hL) (De Vita et al, 2007a) (Table 2).…”

“…All the modern varieties presented significantly higher HI values: within 0.24-0.37. The increase in HI as a function of the year of cultivar release was described in detail in previous studies concerning both durum and common wheat genotypes (De Vita et al, 2007b;Giunta et al, 2007). Besides the dwarf habitus, the rise in HI values was associated with the highest number of kernels per square metre, while other parameters such as number of spikelets per spike and spike length, did not show a clear trend in relation to breeding improvements.…”

“…The highest yield value was obtained for the old variety Urria 12 (4.0 t/ha) along with other durum wheat genotypes, such as Iride (3.8 t/ha), Orobel (3.9 t/ha), Solex (3.9 t/ha) and Svevo (3.9 t/ha). The lowest pro- (Quaranta et al, 2010;De Vita et al, 2007b;Giunta et al, 2007). These studies described high variability comparing durum wheat varieties released before and after the Second World War, reporting a significant rise in productivity of the newest varieties due to increasing spike fertility and density (spikes per square metre).…”

Among cereals, durum wheat has a central role in the Italian diet and economy, where there is a historical tradition of pasta making. In the present study, we evaluated the nutrient and nutraceutical properties of 2 old and 6 modern durum wheat varieties grown under low input agricultural management. Considering the lack of available data on the adaptability of existing durum wheat varieties to the low input and organic sectors, the research aimed at providing a complete description of the investigated genotypes, considering the agronomic performance as well as the nutrient and phytochemical composition. The experimental trials were carried out at the same location (Bologna, Northern Italy) for two consecutive growing seasons

In increasingly competitive conditions, the dominant trend of enlarging the production area of farms is causing a growth in transportation costs making the profitability of cultivating distant plots questionable. The aim of this study was to provide a method to evaluate the rationality of using a plot depending on its distance, area and cultivation technology. An algorithm and a mathematical model were composed to calculate the total costs depending on the distance to the plot. The transportation costs of machines and materials, cost of organisational travel and timeliness costs are taken into account in the model to enable determination of the maximum distance or the minimum area of the plot necessary for profitable cultivation. Simulations allow us to conclude that the growth in yield and selling price of the production allow an increase in the limit value of driving costs and, thus, the profitable distance of the plot; on the other hand, it means also an increase of timeliness costs as a limitation for extending distance. Exploitation of more distant plots can be uneconomical in coming years because of increasing fuel costs.

“…Various approaches have been used. For example, progress has been evaluated from the differences between historic check cultivars and the mean yield of highest yielding lines, cultivars from different eras in common environments (Giunta et al 2007), or materials derived from successive cycles of recurrent selection (RS) (Maich and Di Rienzo 2014).…”

The objective of the present investigation was to examine the relationships between agronomical behavior and grain quality along ten cycles of a recurrent selection program performed under rainfed condition. Twenty-four lines, four for each one of the 0, 2, 4, 6, 8 and 10 cycles of recurrent selection, were evaluated for two consecutive years (2011 and 2012). The experimental lines were evaluated under conventional (CT) and no tillage (NT) systems. Grain yield and grain weight were determined and harvest index and grain number estimated. Flour protein content, sodium dodecyl sulphate sedimentation (IS-SDS) and lactic acid SRC (LASRC) were considered as end-use quality predictive tests. The Spearman correlation coefficient was used to measure the relationships among yield, its components and grain quality parameters. Within the context of CT, flour protein content was negatively associated with all the agronomic variables. The IS-SDS has a negative association with the grain weight; meanwhile, LASRC associated positively with all the agronomic variables. When wheat was grown in NT, the relationship between IS-SDS and harvest index, like LASRC with all agronomic traits, was positive. Confining the discussion to the CT results, after ten cycles of recurrent selection the highest grain yield achieved was accompanied by a decrease in protein percentage. However, the decrease in the percentage of protein in more advanced selection cycles was offset by an improvement of its quality.
