    ABSTRACT: With the aim of studying the agronomic and phytopathological behavior, as well as the industrial quality and grain yield stability of 20 bread wheat varieties that are grown under rainfed conditions in the Central Plateau of Mexico, we set up assays in 11 localities of the State of Mexico which are representative of the rainfed environments of this region. We identified two groups of varieties, one with high and the other with moderate yield; the first group included the varieties Chicalote "S", Rebeca F2000, Náhuatl F2000, Pastor F2000, Triunfo F2004 and Tlaxcala F2000.The varieties developed for irrigated cultivation in the region of El Bajío did not have a good yield and were susceptible to diseases. Other varieties, such as Era F2000, Finsi 2000, Batan F96, Juchi F2000, Pavón F76, Gálvez M87, Temporalera M87 and Zacatecas VT74, which were released for rainfed cultivation, are no longer suitable to be planted due to their low yield and/or susceptibility to diseases. Rebeca F2000, Náhuatl F2000, Tlaxcala F2000, Triunfo F2004, Tollocan F05, and Pastor F2000 showed good resistance against foliar diseases. The varieties with better industrial qualities were: Chicalote "S", Rebeca F2000, Náhuatl F2000, Triunfo F2004, Tlaxcala F2000, Romoga F96, Tollocan, Gálvez M87, Finsi F2000, Era F2000 and Juchi F2000: The first five of this list were also the more stable.

    ABSTRACT: The objective of this research was to analyze the socioeconomic conditions of families in Nanacamilpa, Tlaxcala, and the role of the generation and technology transfer in improving the living conditions of families as important elements of a strategy to promote regional agricultural development. This study was conducted in the community of Nanacamilpa, Tlaxcala, in 2008. Strategies for regional agricultural development legitimized by various international organizations, has been gaining theoretical consistency in the impact on the fight against poverty reduction, social and cultural marginalization, gender and environmental degradation; as to reduce the gap in the transfer of technology in rural development. At a regional and international level, the strategy of the National Institute of Research forAgriculture, Forestry and Livestock (INIFAP), has included the support for agricultural research focused on the farmers. It will be a challenge for the institutions to meet the changing demands of technology that emerges from a new macroeconomic context, under the neoliberal paradigm. The base information was obtained from a simple random sample and a questionnaire was applied to 50 farmers with closed and open questions. The salient findings are: i) technology transfer plays an important role in achieving successful actions for regional agricultural development; ii) the quality of life for families in Nanacamilpa has a higher level of income earned through wheat; iii) the technology transfer promoted by INIFAP stimulates an agricultural development in Nanacamilpa; iv) the generation of technology in the community is an important factor in the transfer and adoption of knowledge; and v) the strategy includes a participative action from all family members.

    ABSTRACT: Land races of durum wheat (Triticum turgidum var durum), called "ventureros", collected in the Oaxaca state of México, showed resistance to durum leaf rust (Puccinia triticina E.) race BBG/BN that affects mainly durum wheats. Four of these collections were crossed to the susceptible durum wheat cultivars "Altar C84" and "Atil C2001", in order to determine the genetics of the resistance to leaf rust in their offspring. The collections resulted genetically heterogeneous. Consequently, their response to resistance depended on the plant used as parent. In the collections "CWI52201" and "CWI52271" two cases of resistance were found: one conferred by a dominant gene and one conferred by two duplicated epistatic recessive genes; in the last one and in most crosses the resistance was conferred by two dominant genes; in the rest of the crosses resistances was due to two duplicated recessive genes. The same result regarding inheritance of resistance was found in collections "CWI52274" and "CWI52345", except that conferred by two duplicate recessive genes.

    ABSTRACT: In order to know the possibilities of producing crystalline wheat with good yields and quality in rainfed areas of High Valleys of Mexico, an experiment was established in four different production environments, where wheat varieties Topacio C98, Júpare C2001 and Gema C2004 were tested and compared with bread wheat varieties Rebeca F2000 and Tlaxcala F2000, which were developed for rainfed conditions; genotypes were evaluated with and without fungicide application. The results indicate that the bread wheat varieties overcame for its agronomic and yield characteristics to the durum wheat in all the testing sites, obtaining higher yields up to 20% (1 200 kg ha-1). Bread wheat had higher yields and was the best option in evaluated favorable production environments and the best alternative in critical environments. Due to its agronomic performance and yield, Júpare C2001 was the durum wheat with better response and adaptation in the tested environments. The industrial quality of durum wheat in any condition, allowed obtaining suitable semolina for the manufacture of good quality products, but its production under rainfed conditions could be an alternative for using it as a flour mixtures improver.

    ABSTRACT: The changes in the stability of wheat quality in response to agro-environmental variations affect the efficient selection in breeding programs. The aim of this study was to determine the effects of allele combinations of glutenins of high (G-BPM) and low (G-BPM) molecular weight upon the distribution of gliadinand glutenin-rich fractions, and the stability of industrial quality characteristics of flour from a group of 26 lines of seasonal wheat. Five agro-environmental conditions were generated for cultivation by agronomical management, in the autumn-winter 2006-2007 cycle, in Celaya, Guanajuato, Mexico. Flour protein fractionation in 50% propanol was performed to obtain fractions rich in monomeric protein or gliadin (50PS) or rich in polymeric protein or glutenin (50PI), determining the 50PS/50PI ratio. Protein quantification was performed spectrophotometrically at 280nm. Mixograph mixing time (TMA), dough strength (ALVW) and stretchability (ALVPL) were evaluated. Most quality characteristics showed a lineal tendency through the environments, yielding a similar quality in the different agro-environmental conditions. The most stable combination for 50PS and 50PI was 2*,17+18,2+12/Glu-A3e,Glu-B3h,Glu-D3b. The combination 2*,17+18,2+12/Glu-A3e,Glu-B3g,Glu-D3b yielded a higher protein amount and a higher 50PS/50PI relation in restrictive environments. The ideal variety is that with an optimal value and a low variation in quality parameters along an ample environmental quality spectrum. It is difficult to find genotypes with good quality and great stability in all of the environments.

    ABSTRACT: Presence of translocation 1BL.1RS (rye secalin proteins) in wheat genome, it has been associated with differenteffects on grain quality and dough rheology, depending on genetic background in which is evaluated. This is reason why aim of the present investigation was to compare physical characteristics of grain of high and low molecular weight glutenins (HMWG and LMWG) combinations with and without translocation in F7 recombinant lines, derived from breeds Gálvez M87¿Bacanora T88 and Bacanora T88¿Salamanca S75. The materials were cultivated in the Experimental Field Bajío, Roque, Guanajuato, during 2008 spring-summer cycle. The identification of glutenins combinations with and without translocation (identified as allele Glu-B3j), and determination of grain physical parameters, was carried out in quality laboratory from International Maize and Wheat Improvement Center (commonly known as CIMMYT for Centro Internacional de Mejoramiento de Maíz y Trigo). Measured variables were, hectoliter weigh, grain hardness, protein in grain and protein in flour. Translocation was identified in six and two different recombinant combinations in breed GálvezM87*Bacanora T88 and Bacanora T88*Salamanca S75, respectively. The analysis of allele Glu-B3j presence in different combinations of HMWG and LMWG, it allowed to identify lines that were associated to high and low values of hectoliter weigh, same behavior was seen for protein in grain and flour; while in both breeds translocation was associated to greater grain hardness.

    ABSTRACT: El origen del gen de resistencia Lr14a a roya de la hoja causada por Puccinia triticina E. es el trigo tetraploide 'Yaroslav emmer' (Triticum dicoccum L.). En México, todas las razas de trigo harinero (T. aestivum) importantes son virulentas a este gen. Sin embargo, las razas que atacan trigos cristalinos o duros son avirulentas a Lr14a. Se ha determinado la presencia de Lr14a en trigo harinero y en especies silvestres tetraploides, pero no en trigos cristalinos o trigos duros (T. turgidum spp durum). El gen Lr14a se transfirió a la variedad cristalina 'Altar C84' a partir de la cruza de ésta con la línea monogénica de trigo harinero 'RL6013' (Selkirk/6*Thatcher) y una retrocruza hacia 'Altar C84'. Para determinar la genética de la resistencia de la variedad 'Jupare C2001', resistente a la raza de roya de la hoja que venció la resistencia de 'Altar C84', y determinar si 'Jupare C2001' posee Lr14a, se cruzó con 'Altar C84' y con 'Altar C84'+Lr14a. La respuesta del gen de resistencia a roya de la hoja Lr14a a la infección en plántula a las razas BBG/BN y BCG/BN que son virulentas en 'Altar C84', es de heterogénea con uredinios grandes (X a X+) en la escala de 0-4, tanto en trigos harineros como en 'Altar C84', mientras que confiere casi inmunidad en planta adulta a estas mismas razas. La cruza de 'Jupare C2001' con 'Altar C84'+Lr14a indicó que 'Jupare C2001' no posee Lr14a, y que la resistencia de esta última se basa en dos genes complementarios dominantes. Para el funcionamiento efectivo de la resistencia que el gen Lr14a confiere en trigos cristalinos en respuesta a las razas de roya de la hoja que preferentemente atacan trigos harineros, es necesaria la presencia del gen de 'Altar C84'.

    ABSTRACT: Con el propósito de determinar las combinaciones alélicas de gluteninas de alto peso molecular (G-APM) y estudiar la estabilidad conferida por dichas combinaciones sobre las propiedades reológicas de la masa en trigos harineros mexicanos, se evaluaron las variedades 'Náhuatl F2000', 'Pavón F76', 'Temporalera M87', 'Rebeca F2000', 'Tlaxcala F2000', 'Gálvez M87', 'Zacatecas VT74','Romoga F96', 'Juchi F2000' y 'Batán F96'. Los genotipos se sembraron en 22 ambientes de temporal o secano en los Estados de México, Tlaxcala, Jalisco, Oaxaca, Puebla, Guanajuato, Morelos y Querétaro, durante los ciclos P-V/1999 y 2000, bajo un diseño experimental de bloques completos al azar con dos repeticiones. Se evaluaron las propiedades viscoelásticas (reológicas) de la masa mediante las variables tiempo de amasado (min), alveograma-W, alveograma-P/L y alveograma P/G. Se estimaron los parámetros de estabilidad mediante cuatro modelos diferentes. Las variedades 'Náhuatl F2000', 'Pavón F76' y 'Temporalera M87' poseen las subunidades de G-APM en Glu-A1 2*, Glu-B1 17+18 y Glu-D1 5+10 (combinación 1); las variedades 'Rebeca F2000', 'Tlaxcala F2000', 'Gálvez M87', 'Zacatecas VT74' y 'Romoga F96' en Glu-A1 1, Glu-B1 17+18 y Glu-D1 5+10 (combinación 2); y las variedades 'Juchi F2000' y 'Batán F96' en Glu-A1 2*, Glu-B1 7+9 y Glu-D1 5+10 (combinación 3). Hubo diferencias significativas (P lt; 0.01) en todas las propiedades viscoelásticas para las combinaciones de G-APM. La combinación alélica 2 fue la más estable sobre las propiedades reológicas de la masa, y fue superior en algunas características viscoeláticas como fuerza de la masa. Por tanto, las variedades que poseen esta combinación son muy deseables para la industria mecanizada.

    ABSTRACT: The stem rust caused by Puccinia graminis Pers. f. sp. Avenae is considered the biotic factor that affects the most to oat cultivation (Avena sativa L.), decreasing yield and grain weight in susceptible varieties, in 75% and 60%, respectively. The strategy that has supported control of this disease is the use of resistant varieties, constantly requiring of resistance sources. The way resistance works, and the genes that give it to oat germoplasm, is still unknown, then is necessary to make more studies about number and similarity of genes as well as in their activity. The aim of the study was to determine similarity and number of resistance genes in mature plant and seedlings, in families F3 of crosses between oat parents, moderately resistant to stem rust; due their importance for the programs of improvement as resistance sources, by means of analysis of the derived progenies of cross between them from 2006 to 2009. In greenhouse seedling state, the parents, considering each one apart, had readings of 0, ";", and 1, indicating their resistance to isolation PgaMex99.13. The families F3 of all breeds didn't segregate susceptible families, indicating that these six parents have a gene in common conferring resistance against tested isolation. In field, even with inoculations of same isolation, the families in all breeds showed differentinfection levels, some above at 60% indicating the incidence of other breeds different to the one inoculated, for which the resistance gene common in the parents was not effective.

    ABSTRACT: Wheat yellow rust caused by Puccinia striiformis f. sp. tritici could infringe huge losses in the wheat yield crop (Triticum aestivum L.), planted under irrigated conditions during the winter season in Mexico. This is in part due to the fact that the fungus have the capacity to evolve and overcome previously resistant varieties. Because of the presence of new forms of virulence, during the crop seasons autumn-winter 2005-2006 and 2006-2007 the virulence analysis of this pathogen was carried out in irrigated wheat production areas in the states of Guanajuato, Jalisco, Sonora and Baja California Norte. Rusted leaves and heads were collected and processed at the International Center for Wheat and Maize Improvement (CIMMYT). Race identification was done by means of 24 wheat yellow rust differentials. During the crop season 2005-2006, 16 different races were identified, whereas during 2006-2007 12 races were identified in the states of Baja California Norte, Sonora, Jalisco and Guanajuato. During the crop season of 2005-2006 in Baja California Norte virulence for the resistance genes Yr1, 2, 6, 7, 8, 9, 17, 27, Poll and A were present, whereas in Guanajuato and Sonora virulence for genes Yr1, 2, 6, 7, 8, 9, 17, 27, y A.was found. During the crop season of 2006-2007 in Sonora virulencia for Yr1, 2, 3, 6, 7, 9, 17, 27, Poll and YrA was found. Virulence for the yellow rust resistance genes Yr1, 2, 6, 7, 9, 17, 27, Poll and A were found in the states of Jalisco and Guanajuato. During the season of 2006-2007 virulence for Yr8 was not found; but virulence for Yr1, 2, 3, 6, 7, 8, 9, 17, 27, Poll and YrA was present. None of the races identified is associated with the presence of one resistance gene in particular but the presence of virulence for Yr27, Yr2 and some other non-identified race-specific resistance genes obligate to plant breeder to considerer the presence of this disease before a new variety is released, specially in those areas where yellow rust was not considered as problem before 2001.

    ABSTRACT: En México, la agresividad de fitobacterias que atacan al trigo (Triticum aestivum L.) no se ha evaluado por su efecto en el crecimiento inicial de las plántulas. En Montecillo, Edo. de México, durante la Primavera 2004, en camas de arena se evaluó el efecto de tres métodos de inoculación de bacterias en la var. ¿Seri M82¿ de trigo: 1) Inoculación de plántulas por aspersión; 2) Infiltración a semillas por vacío; y 3) Punción de plántulas. Se emplearon dos cepas de Pseudomonas syringae pv. syringae (150-3, 151-3), dos de P. fuscovaginae (21-5, 169-2) y tres de Stenotrophomonas maltophilia (150-2, 150-4 y 200-8). Los indicadores de la agresividad bacteriana fueron la longitud de plántula, el número de plántulas enfermas y la producción de materia seca de la parte aérea a los 17 y 34 d después de la emergencia (dde). Se empleó un diseño de bloques completos al azar, en arreglo de parcelas divididas con cuatro repeticiones. A los 17 dde el número de plántulas enfermas no presentó diferencias (P ≤ 0.05) entre cepas ni entre métodos de inoculación. En cambio, a los 34 dde sólo la producción de materia seca en la parte aérea permitió detectar diferencias (P ≤ 0.05) entre cepas, métodos de inoculación y la interacción entre ambos factores. Se concluye que la producción de biomasa, como criterio de agresividad bacteriana, fue mejor indicadora que el número de plántulas enfermas y la longitud de la plántula. La aspersión fue el mejor método de inoculación, porque redujo más la producción de materia seca aérea de la plántula. La cepa más agresiva varió según el método de inoculación; i. e., S. maltophilia (cepa 150-4) cuando el inóculo se asperjó, y P. fuscovaginae (cepa 169-2) al infiltrarla en semillas por vacío.

    ABSTRACT: Con el proposito de determinar la influencia de subunidades especificas de los genomas A y B de gluteninas de alto peso molecular (G-APM) sobre la fuerza y extensibilidad del gluten de la masa y volumen de pan de trigo harinero (Triticum aestivum L.), se probo un grupo de 98 lineas obtenidas de la cruza Rebeca F2000¿~Baviacora M92 derivadas por la descendencia de una sola semilla de F2 a F6. Los genotipos y los progenitores se sembraron en dos localidades del Campo experimental Valle de Mexico del Instituto Nacional de Investigaciones Forestales, Agricolas y Pecuarias (INIFAP) en el ciclo primavera-verano 2004. Se estudiaron los alelos 1 y 2* del genoma A, 7+9 y 17+18 del genoma B. El analisis de variables de calidad y la identificacion electroforetica de las gluteninas de alto peso molecular se efectuo en el laboratorio de calidad de trigo del Centro Internacional de Mejoramiento de Maiz y Trigo (CIMMYT). La calidad del gluten se evaluo con base en volumen de sedimentacion, tiempo de desarrollo de masa, estabilidad al amasado, tolerancia al sobreamasado, alveograma-W y P/L, y volumen de pan. La combinacion 2*, 17+18, 5+10 de G-APM, mostro los mejores valores de fuerza y extensibilidad del gluten (p.0.05) seguida por las combinaciones 1, 17+18, 5+10, 1, 7+9, 5+10 y 2*, 7+9, 5+10. Al sustituir el alelo 7+9 por el 17+18 del genoma B, se observo incremento en extensibilidad y volumen de pan (p.0.05), lo cual indica que el alelo 17+18 tiene una mejor contribucion panadera que 7+9. No se observaron diferencias significativas entre los alelos 1 y 2* del genoma A (p.0.05).
