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...
To study yield, yield component and some morphological traits in cotton, six parents with 15 hybrids (totally 21 genotypes) were evaluated using a randomized complete block design with three replications at a salty farm Bandar Torkaman area in 2005. Nine traits were measured including the percentage of germination, plant height, number of monopodial branches, length of monopodial branches, numb...
in order to study genetic diversity and detection relationship among agronomy traits, 169 barley recombinant inbred line (generation=rils) and their parents “igre” and “arigashar”, were planted in a simple lattice design with two replications. ten agronomic traits were scored on three randomly selected plants. the purpose of this study was detection of phenotype and genotype correlation between...
Genotypic variation is useful to breeders when selecting genotypes to improve particular traits. Inorder to study of genetic diversity 20 genotypes of Hordeum murynum studied in the form of randomized complete block design the experimental field of islamic azad university shahre rey branch with 3 replication in the year 2012. Notes traits was conducted including days to heading, days t...
Improving yield is a major objective for cotton breeding schemes, and lint yield and its three component traits (boll number, boll weight and lint percentage) are complex traits controlled by multiple genes and various environments. Association mapping was performed to detect markers associated with these four traits using 651 simple sequence repeats (SSRs). A mixed linear model including epist...
Identification of easily measured physiological traits contributing to yield under specified environmental conditions would benefit genotypic selection for grain sorghum. A field experiment was conducted to determine broad-sense heritability and expected genetic advance, and to examine the relationships of grain yield with 11 physiological traits related to developmental periods, vegetative gro...
In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...

Genetic diversity is the basis of breeding studies in many plant species and is one of the most important indicators for selecting parents. The aim of this experiment was to investigate the genetic diversity of tall fescue (Festuca arundinacea) using agronomic traits such as plant height, spring growth score, days to flowering, days to pollination, flag leaf length and width, panicle length, we...
Yield is a quantitative trait and improving grain yield through direct selection is time-consuming. Indirect selection consisting of selection indices is more promising. A field experiment was conducted during 1999-2000 growing season in two experimental locations (Kooshkak and Badjgah) of College of Agriculture, Shiraz University, Shiraz. Thirteen corn hybrids were used in a randomized complet...
