Soil salinization is one of the major problems in global agricultural production. Cotton is a pioneer crop with regard to salt stress tolerance, and can be used for saline-alkali land improvement. The large-scale detection of salt tolerance traits in cotton accessions, and the identification of elite quantitative trait loci (QTLs)/genes for salt-tolerance have been very important in salt tolera...
In order to study agronomic and morphological traits in maize hybrids in Hammedan, two early (108 and 301), three medium (604, 647 and TWC647) and two late maturing (704 and 711) hybrids were evaluated in a randomized complete block design with three replications in Agricultural and Natural Resources Research Station in Hammedan in 2005. 33 morphological and phonological traits were recorded fr...
Genetic and phenotypic parameters for sow productivity traits were derived from analyses of records for 999 purebred Duroc and Yorkshire litters at the Beltsville Agricultural Research Center. Included were 682 spring-farrowed litters and 317 fall-farrowed litters. Primary traits examined were number of pigs born alive in the litter (NA), litter size at 21 d of age (N21), litter weight at 21 d ...
Water availability is a major limiting factor for wheat (Triticum aestivum L.) production in rain-fed agricultural systems worldwide. Root architecture is important for water and nutrition acquisition for all crops, including wheat. A set of 158 diverse wheat genotypes of Australian (72) and Indian (86) origin were studied for morpho-agronomical traits in field under irrigated and drought stres...
Experiment was designed to establish a more defi nitive relationship of phenological and physiological traits with yield in wheat using twenty fi ve spring wheat genotypes. Because many of these traits are interrelated, correlation coeffi cient, path analysis and principal component analysis were used to expose these relationships more clearly. Experiment was conducted at the Wheat Research Cen...
In order to study effect of drought stress on morphologic traits, yield and yield components of 28 new hybrids of corn to heat and drought stress in addition 6 commercial hybrid (as control), an experiment was carried out on based of complete randomized block design with three replication under normal irrigation and drought stress in Khorasan Razavi Agricultural Research and Natural Resources I...
in order to study morphological traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based on of randomized complete block design with three replications under normal irrigation condition in khorasan razavi agricultural research and natural resources center, mashhad, iran on 2009. results of analysis of variance showed that there were significant differences b...
In order to study the genetic control of root yield, sugar yield and white sugar yield in tropical beet, the biplot of diallel data was used. 36 hybrids derived from crosses among 9 sugar beet genotypes along with four control treatments were evaluated at Safiabad Agricultural Research Center, Dezful, Iran during 2008-2009 growing season. The experimental design was a triple lattice design with...
Abstract Terminal drought stress is one of the most important environmental stresses affecting plant morphology and physiology and has major effects on agricultural production. The purpose of this experiment was to investigate the effect of water deficit stress on changes in physiological traits of wheat in a randomized complete block design with three replications in two cultivation years of ...
Biogen base serves the maize (Zea mays L.) research community by making a wealth of genetics and genomics data available through an intuitive Web-based interface. We have developed an Open access database as a resource to enhance research with the unique data obtained from the genomics and proteomics lab of TNAU. Biogen Base is an interactive database in bringing out the different traits of the...
