La calidad industrial de la masa y su relación con diferentes loci de gluteninas en trigo harinero (Triticum aestivum L.)

The dough strength and extensibility of bread wheat (Triticum aestivum L.) depends partly on the alleles of high molecular weight glutenins (HMWG) and low molecular weight glutenins (LMWG) in flour. The objective of this research was to identify the effect of eleven allelic variants on dough quality of recombinant Fg lines, derived from Rebeca F2000XBacanora T88, Verano...

Plant Sources, Extraction Methods, and Uses of Squalene

Squalene (SQ) is a natural compound, a precursor of various hormones in animals and sterols in plants. It is considered a molecule with pharmacological, cosmetic, and nutritional potential. Scientific research has shown that SQ reduces skin damage by UV radiation, LDL levels, and cholesterol in the blood, prevents the suffering of cardiovascular diseases, and has antitumor and...

Overexpression of Grain Amaranth (Amaranthus hypochondriacus) AhERF or AhDOF Transcription Factors in Arabidopsis thaliana Increases Water Deficit- and Salt-Stress Tolerance, Respectively, via Contrasting Stress-Amelioration Mechanisms

Two grain amaranth transcription factor (TF) genes were overexpressed in Arabidopsis plants. The first, coding for a group VII ethylene response factor TF (i.e., AhERF-VII) conferred tolerance to water-deficit stress (WS) in transgenic Arabidopsis without affecting vegetative or reproductive growth. A significantly lower water-loss rate in detached leaves coupled to a reduced...

Grain Amaranths Are Defoliation Tolerant Crop Species Capable of Utilizing Stem and Root Carbohydrate Reserves to Sustain Vegetative and Reproductive Growth after Leaf Loss

Tolerance to defoliation can be defined as the degree to which productivity is affected by photosynthetic area reduction. This trait was studied in grain amaranth (Amaranthus cruentus and A. hypochondriacus), which are considered to be a highly defoliation-tolerant species. The physiological and biochemical responses to increasing levels of mechanical leaf removal up to total...

Nana F2007, cultivar de trigo para siembras de temporal en México

Nana F2007 was developed by the National Wheat Program of the INIFAP and evaluated from 2005 to 2012. This variety is of spring growth habit, with semi-erect carriage at tillering and stem tolerant to lodging, with an average height of 84 cm on average. It is classified as a variety of early cycle, 85 days to 134 days maturity in drought environments rainy, like Gálvez M87, N...

Rendimiento y calidad de semilla de avena en función de la fecha y densidad de siembra

The oat crop has great importance in Mexico, as it has increased its area planted in the last 15 years. In years with rainfed delay or long periods of drought, has promoted the planting of this cereal in extensive disaster areas, however, the seed supply is insufficient and its demand is so high, that promotes the trade of dubious quality seed. In Mexico there is still no...

Variabilidad cualitativa y cuantitativa de accesiones de amaranto determinada mediante caracterización morfológica

The classification within the genus Amaranthus has been quite difficult, mainly because highly segregating characters within the populations have been considered for this. The aim of this study was to morphologically characterize Amaranthus spp., germplasm in order to know the existent qualitative and quantitative variability in the INIFAP's collection of the genetic resources...

Áreas prioritarias para colectar germoplasma de Amaranthus en México con base en la diversidad y riqueza de especies

This investigation had as objective to use the Geographical Information System, to create maps of indexes of diversity and wealth of species of genus Amaranthus in Mexico, to plan the best areas of germplasm collection. The maximum wealth of species was in west center of State of Mexico including Distrito Federal and the Pacific coast, between Jalisco and Colima, as well as in...

Distribución geográfica de las especies cultivadas de Amaranthus y de sus parientes silvestres en México

The aim of this work was to obtain the distribution patterns of Amaranthus cruentus, Amaranthus hypochondriacus and its wild relatives using Gorgraphic Information Systems, as well as creating a geographic variation pattern of the areas in which they are found. The genus Amaranthus is distributed throughout Mexico. A. cruentus and A. hypochondriacus are distributed in the south...

Fertilización y densidad de plantas en variedades de amaranto (Amaranthus hypochondriacus L.)

The amaranth is a potential crop that is gaining importance in Mexico, because every day there is more demand. This crop is grown under conventional tillage systems and transplant, recently opening up new areas of cultivation used in irrigation and mechanical harvesting. The technology package for the production of amaranth is not fully defined, so that in order to determine the...

Variación genética de la resistencia A Puccinia triticina E. en trigos duros de Oaxaca, México

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...

Estudio de caso del impacto de la transferencia de tecnología en trigo del INIFAP

The goal of this research was to identify the factors that favor or limit the use of bred wheat cultivars that have been developed by the breeding program of the National Research Institute for Forestry, Agriculture and Livestock (INIFAP). The study was conducted during 2006 in the Nanacamilpa county, Tlaxcala, Mexico, where wheat cultivation is an important component in the...

Estabilidad a través de ambientes de las propiedades reológicas de trigos harineros en función de sus gluteninas de alto peso molecular

Josecha F2007, nueva variedad de trigo harinero para la región de El Bajío y zonas de riego del norte de México

Josecha F2007 was developed by the wheat breeding program of INIFAP at the Bajio Experimental Station, Celaya, Guanajuato. Josecha F2007 takes 83 days to flowering and 128 to maturity, produces 8.7% higher yield than Barcenas S2002 and 8.7% than Kronstand F2003 under irrigated conditions. Josecha F2007 has higher resistance to stripped and leaf rust than the commercial wheat...
