We have developed an approach combining physiology and quantitative genetics to enhance our understanding of nitrogen (N) metabolism during kernel germination. The physiological study highlighted the central role of glutamine (Gln) synthetase (GS) and Gln synthesis during this developmental process because a concomitant increase of both the enzyme activity and the amino acid content was observe...

objective: wheat is the most important crop in iran. self sufficiency in wheat production is one of the economic and food safety policies in the country. in spite of the efforts which have been made in this area, the mean of wheat yield in iran is less than its world average. methods: in order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...

Purpose. Identification of spring barley promising breeding lines with combination adaptive traits under conditions the central part Ukrainian Forest-Steppe. Methods. Field trial, laboratory-field analysis drought tolerance, statistical and graphical experimental data. Results. The variance AMMI model showed that largest contribution to general variation (85.78%) had environmental (years resear...

OBJECTIVE To obtain information on the hospital mortality of infants born in Fortaleza with birth weights less than or equal to 1,500 g, and to compare it with data from the Vermont Oxford Network, a center of excellence for neonatal care. METHODS Prospective cohort study, enrolling all infants with birth weight less than or equal to 1,500 g born in Fortaleza between March 1, 2002 and Februar...

Stable quantitative trait loci (QTL) are important for deployment in marker assisted selection in wheat (Triticum aestivum L.) and other crops. We reported QTL discovery in wheat using a population of 217 recombinant inbred lines and multiple statistical approach including multi-environment, multi-trait and epistatic interactions analysis. We detected nine consistent QTL linked to different tra...

Cereal Chem. 86(2):239–246 Test weight and groat proportion are two very important quality characteristics of oat grain. In this study, we pose the hypothesis that these two characteristics are related through characteristics of grain density. Test weight is defined as the product of kernel density and packing proportion. Groat proportion, in theory, is the ratio of the groat mass to the kernel...

Chromosomal locations of the stable QTL associated with KWPS, SN, KDR, KW, KL, TKW and PH based on a 371 RIL population derived from across between CN18 T1208. The clusters were marked clearly chromosomes.

In this paper we discuss a kernel approach to learning in semantic graphs. To scale up the performance to large data sets, we employ the Nyström approximation. We derive a kernel derived from semantic relations in a local neighborhood of a node. One can apply our approach to problems in multi-relational domains with several thousand graph nodes and more than a million potential links. We apply ...

rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...

Demand is increasing for locally grown malt barley (Hordeum vulgare L.) in northeastern North America, driven primarily by growth the craft beer sector. A multi-site experiment was conducted to evaluate how variety (V), seeding rate (S), and nitrogen (N) fertilizer affect quality northeast. Two varieties (Cerveza Newdale), two rates (200 400 seeds m ?2 ), five of actual applied N fertility (0, ...
