Última VARIACIONES DEL CONTENIDO DE Mn DE DOS SUELOS SOMETIDOS A ESTERILIZACIÓN Y SU EFECTO SOBRE LA PUDRICION RADICAL DEL TRIGO O "MAL DE PIE" 113 Campillo,Ricardo; Andrade,Orlando; Contreras,Eduardo. Se evaluó bajo condiciones controladas de invernadero, el efecto de la variación del contenido de Mn de un suelo supresivo y un suelo conducivo, sobre la expresión de la pudrición radical del trigo (Triticum aestivum L.) o "mal de pie", causada por el hongo ascomicete Gaeumannomyces graminis (Sacc.) von Arx & Olivier var. tritici Walker (Ggt). Se utilizaron dos suelos de la IX Región previamente determinados como: A) naturalmente supresivo (ultisol) y B) como conducivo (andisol) a la pudrición radical del trigo. Se evaluaron ambos suelos sembrados con trigo cv. Dalcahue - INIA durante 40 días, en su condición natural y bajo esterilización con autoclave y microonda, para observar el efecto del contenido de Mn sobre la expresión de la enfermedad. Los...

Ano: 2001 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0365-28072001000300009 Faraón-INIA, a new Winter Triticale (×Triticosecale Wittmack) for Southern Chile 117 Jobet,Claudio; Matus,Iván; Campillo,Ricardo; Romero,Oriela; Madariaga,Ricardo; Alfaro,Cristian. Faraón-INIA is a new winter triticale (×Triticosecale Wittmack) cultivar released by the National Wheat Program of the Instituto de Investigaciones Agropecuarias INIA in Chile. It is derived from an F9 material received from Nordsaat, Germany, under a germplasm exchange agreement signed in 2006 by both institutions. The crossing was Piano/Focus with Nord93.7548 pedigree. Faraón-INIA has a winter growth habit, a short stem (semi-dwarf), with a mean height of 106 cm. The spike is long, compact, decumbent, white, and awned. The grain is soft, yellow, with 1000-grain weight of 36 g, and a mean of hectoliter weight of 76 kg hL-1. It is resistant to stripe rust (Puccinia striiformis West. f. sp. tritici) and leaf rust (Puccinia triticina Erikss.) as well as...

Ano: 2010 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-58392010000400019 Effects of Nitrogen on Productivity, Grain Quality, and Optimal Nitrogen Rates in Winter Wheat cv. Kumpa-INIA in Andisols of Southern Chile 117 Campillo,Ricardo; Jobet,Claudio; Undurraga,Pablo. Nitrogen is one of the main inputs of the winter wheat crop (Triticum aestivum L.) in southern Chile. Nitrogen efficient management is basic to optimizing its utilization while decreasing pollution risks and operational costs. Crop response and N use efficiency (NUE, defined as the ratio of yield to mineral N supply, regardless of source) are important for evaluating N requirements of winter wheat, and reaching maximum and economic yields. The objective of this study was to determine the effect of N rate on grain yield, calculate the N rate that maximizes yield, and estimate the optimal grain yield rate and quality of high-yielding winter wheat cv. Kumpa-INIA. Five annual N rates were evaluated in a randomized complete block design during two successive... Tipo: Journal article Palavras-chave: Nitrogen level; Nitrogen use efficiency; Andisols. Ano: 2010 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-58392010000100013 Soils suppressive against Gaeumannomyces graminis var. tritici identified under wheat crop monoculture in southern Chile 118 Andrade,Orlando; Campillo,Ricardo; Peyrelongue,Amelia; Barrientos,Leticia. Improved knowledge of the biological phenomenon of soil suppressiveness is critical for the management and biological control of soil-borne pathogens. Andisols, which are located in southern Chile, show very high conduciveness to the take-all disease of wheat caused by the fungal soil-borne pathogen Gaeumannomyces graminis var. tritici. However, no previous reports have investigated suppressive soils in this important wheat-producing area. The first part of this study was conducted to identify soils suppressive to the take-all disease, and will be followed by a characterization of its microflora to identify potential bio-control agents against the fungal pathogen. Based on the transferability of suppressiveness into the same sterile soil background, 20...
