Ajowan is one of the most important members of medicinal plants of the Apiaceae, consumed by humans. The aim of this study was to explore genetic variability of 20 ajowan populations by ISSR fingerprinting and evaluation of traits at germination. Out of the 30 ISSR primers, ten generated reproducible and polymorphic bands. A total of 93 bands were detected out of which 65 were polymorphic. High...
This experiment was conducted to evaluate genetic diversity in 72 peanut accessions (Arachis hypogaea L.), which introduced from seed bank of Australia in training and seed production research center of oilseeds company, Iran. Twelve major morphological traits recorded during 2013 growing season using a randomized complete block design with three replications. The results showed that the differ...
Gladiolus (Gladiolus floribundus L.) is a bulbous ornamental plant belongs to family Iridaceae. It is an elegant cut flower grown for its magnificent spikes. The estimates of heritability varied from 99.5% to 61.1%. The highest heritability estimates in broad sense was observed for the characters vase life (99.5%) and lowest for height at 30 days after planting. Expected genetic advance express...
Maize silage is fundamental for high milk production in dairy farming. The incorporation of new genetic diversity into temperate maize germplasm has the potential to improve adapted cultivars, and it could be especially useful improving nutrition varieties. goal this study assess lines from Germplasm Enhancement (GEM) project compete with commercial hybrids when crossed elite temperate-adapted ...
The linear mixed model (LMM) is now routinely used to estimate heritability. Unfortunately, as we demonstrate, LMM estimates of heritability can be inflated when using a standard model. To help reduce this inflation, we used a more general LMM with two random effects-one based on genomic variants and one based on easily measured spatial location as a proxy for environmental effects. We investig...
In order to evaluate the morphological and agronomic characteristics of 19 land races of onions and one foreign cultivar (Yellow Sweet Spanish), an experiment was conducted in 1998 at the Research Farm of the College of Agriculture, Isfahan University of Technology. Analysis of variance showed significant differences among genotypes for all of the morphological and agronomic traits. Dry weight ...
In order to study mode of gene action in rice for the traits related to yield, four varieties of rice were investigated. Direct and reciprocal crosses have been done between parents Sang-Tarrom and Gerdeh, IR229 and IRRI2 and their back crosses. The F1 and BC seeds were grown in 2006 and F1 plants were selfed for obtaining F2 seeds. Therefore, 10 different populations (generations) including ...
Genetic diversity is the base of plant breeding. In present study 19 chemical and morphological traits in 36 genotypes were investigated with a 6×6 simple lattice design in Tirtash Education and Research Center. Results showed significant differences among genotypes for all studied traits. The highest and the lowest genotypic variation coefficient were related to percentage of sugar and nicot...
In order to study gene action in rice for traits related to quality (gelatinization temperature, gel consistency and amylose content), four varieties of rice (Sang-e-Tarrom, Gerdeh, IRRI2 and IR229) were investigated. Ten different generations including P1, P2, F1, RF1, BC1, RBC1, BC2, RBC2, F2 and RF2 were evaluated using generation mean analysis. In generation mean analysis, one of non-alleli...
Sainfoin (Onobrychis viciifolia Scop.) is widely grown as forage and pasture legume in Iran and is tolerant to environmental stresses. To investigate the genetic diversity among 56 accessions of sainfoin germplasm (including 46 Iranian and 10 foreign) based on morphological and agronomic characteristics, present experiment was conducted as randomized complete block design with three replication...
