    In 1998 CIMMYT and Agrovegetal SA signed an agreement aimed at developing new wheat varieties adapted to agroclimatic conditions of Southern Spain. To select bread wheat cultivars appropriate for Andalusian market is important to meet high protein and bread making quality requirements. The stability of several characters related with bread quality of a set of five new varieties ('Escacena', 'Ecija', 'Olvera', 'Jerezano' and 'Vejer'), and three checks ('Yecora', 'Cartaya' and 'Pinzon') has been tested in samples collected from trials in quadrate lattice with three replicates in five locations of Andalusia during the 2000-2001 and 2001-2002 crop seasons. The quality testing and statistical analysis of the data were conducted at the Genetics Department of the University of Cordoba, showing that in these typical Mediterranean conditions the main part of quality parameters were highly influenced by the environment. The distribution of phenotypic variance showed that the three quality traits in which the genotype was the main factor of variation in the two-year analysis were SDSsedimentation, falling number, and alveograph-W. For the rest of traits the environment or the genotype x environment interaction explained, in at least one year, more than 50% of the observed variance

    The objective of this study was to determine the effect of environmental and genotypic factors on industrial quality and on the monomeric and polymeric protein contents and ratio of 24 rainfed bread wheat recombinant lines. The cultivation was done in five environmental conditions generated by agronomic management in the autumn-winter 2006/2007 cycle, at Roque, Guanajuato, Mexico. The mixing time (TMA), strength (ALVW) and extensibility (ALVPL) of the dough, gliadin (50PS) and glutenin (50PI) rich fractions, and their ratio (50PS/50PI), were evaluated. The best combinations of high and low molecular weight glutenins for TMA and ALVW were 1, 17+18, 5+10/Glu-A3c, Glu-B3g, Glu-D3b; 1, 17+18, 5+10/Glu-A3c, Glu-B3h, Glu-D3b; and 2*, 17+18, 5+10/Glu-A3c, Glu-B3g, Glu-D3b; for ALVPL it was 2*, 17+18, 2+12/Glu-A3e, Glu-B3h, Glu-D3b; and for 50PS they were 2*, 17+18, 2+12/Glu-A3e, Glu-B3h, Glu-D3b; and 1, 17+18, 5+10/Glu-A3e, Glu-B3h, Glu-D3b. The 50PS/50PI ratio was higher in genotypes with 2*, 17+18, 2+12/Glu-A3e, Glu-B3g, Glu-D3b. TMA is higher when temperature increases, and the best ALVPL is found under normal environmental conditions. Gliadin fraction and the 50PS/50PI ratio are higher when sulphur fertilization is done, and 50PI increases with drought and higher temperatures during grain-filling stage.El objetivo de este estudio fue conocer el efecto de factores ambientales y genotípicos sobre los parámetros de calidad industrial y sobre la cantidad y relación de proteínas monoméricas y poliméricas del gluten en 24 líneas recombinantes de trigos harineros de temporal. El cultivo se desarrolló en cinco condiciones ambientales generadas por manejo agronómico, ciclo otoño-invierno 2006/2007, en Roque, Guanajuato, México. Se evaluaron el tiempo de amasado (TMA), fuerza (ALVW), extensibilidad (ALVPL) de la masa, fracción rica en gliadina (50PS) y en glutenina (50PI), y su relación (50PS/50PI). Las mejores combinaciones de gluteninas de alto y bajo peso molecular para TMA y ALVW fueron los genotipos con 1, 17+18, 5+10/Glu-A3c, Glu-B3g, Glu-D3b; 1, 17+18, 5+10/Glu-A3c, Glu-B3h, Glu-D3b, y 2*, 17+18, 5+10/Glu-A3c, Glu-B3g, Glu-D3b; para ALVPL, 2*, 17+18, 2+12/Glu-A3e, Glu-B3h, Glu-D3b; para 50PS, 2*, 17+18, 2+12/Glu-A3e, Glu-B3h, Glu-D3b; y 1, 17+18, 5+10/Glu-A3e, Glu-B3h, Glu-D3b. La relación 50PS/50PI fue mayor en genotipos con 2*, 17+18, 2+12/Glu-A3e, Glu-B3g, Glu-D3b. El TMA es mayor cuando aumenta la temperatura y la mejor ALVPL se obtiene en el ambiente bajo condiciones normales. La fracción 50PS y la relación 50PS/50PI son mayores cuando se realiza la fertilización con azufre, y se obtiene incremento de 50PI con riego limitado y aumento de temperaturas durante el llenado de grano.The objective of this study was to determine the effect of environmental and genotypic factors on industrial quality and on the monomeric and polymeric protein contents and ratio of 24 rainfed bread wheat recombinant lines.

    Sloan Digital Sky Survey IV: mapping the Milky Way, nearby galaxies, and the distant universe

    We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July
