En el presente trabajo se determinó la actividad de alfa amilasas y el Falling Number (FN) en harinas de diez líneas experimentales de tritíceas cultivadas en el Campo Experimental de la Facultad de Agronomía, Universidad Nacional de La Pampa, Argentina. Se realizó la conversión de FN al Número de Licuefacción (LN) para obtener la linealidad de la...

The estimation of genetic parameters such as heterosis (Mh), heterobeltiosis (Hh), general combining ability (GCA) and specific combining ability (SCA) allows inferences about the predominant action of the genes, indicates the appropriate selection strategy, and facilitates identification of the best parents. The present study was carried out using...

Triticale (x Triticosecale Wittmack) is a cereal used in Argentina as a winter seasonal pasture or feeding grain. Efforts made on breeding have led to varieties with potential grain yield similar or greater than with wheat. The aim of this study was to determine the gene effects, heritability, genetic gain, heterosis and inbreeding depression in va...

p>Triticales (x Triticosecale Wittmack) y tricepiros (x Triticosecale Witt. X x Agrotricum A. Camus) se mejoran con la finalidad de obtener cultivares de doble propósito (forraje y grano). Para su utilización en consumo humano, la calidad de las harinas de triticales es frecuentemente evaluada midiendo el diámetro y factor de expansión de las galle...

Grain yield per unit area and some yield components of eighteen experimental strains and three dual-purpose cultivars of triticale were evaluated from 2009 to 2015 in Santa Rosa (36°37' S, 64°17' W), Province of La Pampa, Argentina, on a petrocalcic Paleoustol soil under natural conditions. The trial was conducted using a randomized complete block...

Triticales (x Triticosecale Wittmack) and Tricepiros (x Triticosecale Witt. X x Agrotricum A. Camus) are improved in order to obtain dual-purpose cultivars (forage and grain). In order to use them for human consumption the quality of triticale flour is frequently evaluated by measuring the diameter and spread factor of cookies. These indicators are...

Triticales and tricepiros are good alternatives to fresh forage and grain in livestock meat and dairy systems in Argentina. The development of new cultivars requires good performance and stability in different environments, so it is necessary to know the genotype-environment interaction. In this paper, the genotype x environment interaction, stabil...

En Santa Rosa (La Pampa), se evaluo entre 2008 y 2010 el rendimiento de forraje de 22 genotipos de triticales y tricepiros y de 17 genotipos en la produccion de grano. Se utilizo un diseno en bloques completos al azar con tres repeticiones y siembra en parcela estandar. Las diferencias entre ambientes y genotipos fueron evaluadas mediante Analisis...

A hybrid, named tricepiro, was obtained in 1972, by crossing a hexaploid triticale (2n=6×=42) and an octoploid trigopiro (2n=8×=56). The lines achieved include the tricepiro Don René INTA, which has shriveled kernels, and FA-L2, which has smooth ones. The relationship between the heterochromatin content of the rye chromosomes, the seed weight, the...

WE STUDIED THREE DIFFERENT TRICEPIROS: (Don Santiago x Don Noé), (Cumé x Horovitz) and (Cumé x Don Noé). The tricepiro (Don Santiago x Don Noé) was obtained by crossing the triticale Don Santiago INTA (AABBRR, 2n = 6x = 42) with the trigopiro Don Noé INTA (AABBDDJJ, 2n = 8x = 56). The number of chromosomes for the F(1) was 2n = 49, the most frequen...

An optimized methodology for improving regeneration of maize plants by direct organogenesis was evaluated. Our objective was to obtain genetically homogeneous plants through in vitro methods to regenerate clumps of multiple shoots from shoot tips at high frequency. Cultures were initiated from shoot tips of experimental lines of maize on a Murashig...

Chromosome in situ hybridization (FISH and GISH) is a powerful tool for determining the chromosomal location of specific sequences and for analysing genome organization and evolution. Tricepiro (2n = 6x = 42) is a synthetic cereal obtained by G. Covas in Argentina (1972), which crosses hexaploid triticale (2n = 6x = 42) and octoploid Trigopiro (2n...
