“…turgidum and dicoccon , some MTAs for DH were also associated with other traits, as the MTA for DM in turgidum , and three for the number of SS and one for SL in dicoccon . The positive correlation of DH with DM and number of SS detected in our collection and in a previous study [69] supports the influence of DH on these MTAs and that earliness alleles can reduce spikelet number in southern Europe [70]. In dicoccon landraces, the adaptive western-eastern pattern detected in the MTAs for DH was also identified in the MTAs for the number of SS, SL and PG, which confirmed the geographic substructure east–west previously identified in that subspecies [16].…”

Association mapping was performed for 18 agromorphological and grain quality traits in a set of 183 Spanish landraces, including subspecies durum, turgidum and dicoccon, genotyped with 749 DArT (Diversity Array Technology) markers. Large genetic and phenotypic variability was detected, being the level of diversity among the chromosomes and genomes heterogeneous, and sometimes complementary, among subspecies. Overall, 356 were monomorphic in at least one subspecies, mainly in dicoccon, and some of them coincidental between subspecies, especially between turgidum and dicoccon. Several of those fixed markers were associated to plant responses to environmental stresses or linked to genes subjected to selection during tetraploid wheat domestication process. A total of 85 stable MTAs (marker–trait associations) have been identified for the agromorphological and quality parameters, some of them common among subspecies and others subspecies-specific. For all the traits, we have found MTAs explaining more than 10% of the phenotypic variation in any of the three subspecies. The number of MTAs on the B genome exceeded that on the A genome in subsp. durum, equalled in turgidum and was below in dicoccon. The validation of several adaptive and quality trait MTAs by combining the association mapping with an analysis of the signature of selection, identifying the putative gene function of the marker, or by coincidences with previous reports, showed that our approach was successful for the detection of MTAs and the high potential of the collection to identify marker–trait associations. Novel MTAs not previously reported, some of them subspecies specific, have been described and provide new information about the genetic control of complex traits.

“…Some researchers have tried to explain the mechanism of crop yield increase from the application of N fertilizer through the photosynthetic regulation (Bindraban, 1999;Miranzadeh et al, 2011). Regulation of the photosynthetic physiological processes of plants by N fertilizer, will ultimately effect on yield and water use efficiency (Ruiz et al, 2008). Therefore, understanding the photosynthetic regulation on yield reduction by reduce N fertilization would give us important references for N management.…”

Excessive fertilization is common in North China Plain. It is essential to determine the extent to which reduction of nitrogen application rates has little impact on yield and understand its physiological basis. Two seasons of field experiments were conducted in a winter wheat field with three nitrogen (N) fertilization treatments, i.e. N3, traditional N application rates (290 kg N hm-2), N2, ~65% N application rates of N3 (190 kg N hm-2) and N1, ~40% N application rates of N3 (110 kg N hm-2). Yield (Y) and water use efficiency (WUE) of N2 didn't reduce significantly in both seasons despite that the instantaneous net photosynthetic rates (A n) and stomatal conductance (g s) of N2 were significantly lower than those of N3. Y and WUE of N1 treatment reduced significantly in the second season. The reduction of Y was better indicated by photosynthetic capacity (A max) in the grain filling stage (around 48-50 days after the reviving stage irrigation, Dari 48-50) because A max decrease in this stage was proportionally to Y. The A max and apparent quantum efficiency (α) of N2 measured on Dari 48-50 were not significantly lower than those of N3, which could be the reason of no significant reduction of Y for N2. Thus, the fertilization amount of N2 (190 kg N hm-2) can be applied in this area to keep Y steady for at least two years. Differences of the relationships between A max and biological factors among treatments and non-stomatal limitation of photosynthesis were also discussed. These results are important for understanding the mechanisms of yield reduction by reducing N application and provide scientific basis for application of fertigation.

“…The varieties were sown in a randomised-complete-block design under rainfed conditions at Alcalá de Henares, Madrid. Four cultivars were used as test varieties: 'Senatore Capelli', 'Cocorit-71' and 'Yavaros-79' (described by Ruiz et al, 2008) and 'Don Pedro', released in 1990 and cultivated in the South of Spain.…”

A subset of durum wheat Spanish landraces, previously evaluated for yield at low and high nitrogen (N) levels, was analysed for quality, protein content (P) and sodium dodecyl sulphate sedimentation (SDSS) test. The evaluation was carried out at the two N rates and in two years. The influence of prolamin alleles at the Glu-1, Glu-3, Glu-B2 and Gli-1 loci on quality parameters was also studied. The non significant Variety-by-Year or Variety-by-N interactions suggested that year and N affected all the varieties in a similar manner. Year and N effects were larger than variety effect for P, which increased with N. In contrast, variety genotype exhibited a stronger influence on SDSS test, which was not affected by year and fertilizer. Variety effects on P did not reflect the variety differences for SDSS test. A high positive influence of some prolamin alleles on quality parameters was detected, mainly for SDSS values. No correlation between yield and P was detected in the landraces adapted to low N. Based on the results of yield and quality evaluations, four landraces with high yield and high gluten strength were pre-selected for low N production.Additional key words: cereals, germplasm, gliadins, glutenins, low-N, quality breeding. ResumenEfectos del abonado N, año y alelos de prolaminas en la calidad del gluten en variedades locales españolas de trigo duro (Triticum turgidum L. ssp. turgidum) Se ha evaluado la calidad (contenido en proteína, P, y test de sedimentación con dodecil sulfato sódico, SDSS) de un grupo de variedades locales españolas cuyo rendimiento había sido estudiado previamente para alto y bajo abonado nitrogenado (N). Los parámetros de calidad se han analizado para las dos dosis de N y en dos años. También se ha estudiado la influencia en la calidad de los alelos de prolaminas de los loci Glu-1, Glu-3, Glu-B2 and Gli-1 loci. La existencia de interacciones no significativas Variedad × Año ó Variedad × N indicaron que el año y el N afectaron a todas las variedades de una forma similar. Los efectos del año y del N fueron mayores que el efecto de la variedad para P, el cual aumentaba con el nivel de N. Por el contrario, la variedad influyó más en el test SDSS que no se vio afectado por el año ni el abonado. Los efectos de las variedades en P no reflejaron las diferencias en el SDSS. Se detectó una influencia alta y positiva de algunos alelos de prolaminas en los parámetros de calidad, principalmente en los valores del SDSS. No se detectaron correlaciones entre el rendimiento y P en las variedades adaptadas a bajo N. En función de los resultados se han seleccionado cuatro variedades locales con alto rendimiento y fuerza del gluten para producción con bajo N.
