to evaluate tolerance of rice genotypes (oryza sativa l.) to soil/water salinity and to utilize selected tolerant genotypes in rice breeding program and further agronomy and physilogical studies 56 rice genotypes have been evaluated. of which 40 rice genotypes from international rice research institute (irri) together with 16 selected tolerant rice genotypes have been tested in two separate exp...

in vitro propagated and conventional runner propagated plantlets of strawberry (fragaria×ananassa duch) cv. ‘festival’ were transferred to the field and the size of crown for plants derived from both sources of planting material were compared. four sizes of the crown, i.e., < 0.5, 0.5-0.8, 0.8-1, and > 1 cm were taken from both sources of planting material. the results obtained flashed that veg...

five improved along with three local rice varieties were crossed in a line× tester method in 2001. fifteen f1 hybrids and eight parental genotypes were planted in a randomized complete block design with 3 replications at rice research institute of iran, rasht, in 2002. the main objective of the research was to estimate the general and specific combining ability and gene action for 10 agrnomic a...

in order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (foeniculum vulgare miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. arbuscular mycorrhizal fungi (strain sebacina vermifera) and phosphate dissolving bacteria (genera peseudomonas) were applied as ...

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...

the introduction of canola (oilseed rape; brassica napus l.) as a new source of vegetable oil production in iran prompts evaluation of the performance of this crop under different tillage systems. a field experiment was conducted to determine the impact of depth and intensity of tillage on soil physical properties, crop establishment and yield of irrigated winter canola in a loam soil (typic ha...

five carnation cultivars (‘grand salam’, ‘nelson’, ‘kaly’, ‘cinderella’ and ‘tempo’) were evaluated with respect to growth, yield and quality characteristics under lath house conditions at kala shah kaku research station, directorate of floriculture, lahore during 2011. among the cultivars studied, maximum plant height was recorded in carnation cultivar ‘grand salam’ (78.66 cm) closely followed...

the purpose of this study was to describe the association between grain yield and its components. the experiment was conducted in a randomized complete block design with three replicatsions. results of analysis showed that similar trends were observed for genotypic and phenotypic correlations and in most cases, the value for genetic correlation was greater than phenotypic value. 100-seed weight...
