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...
Half diallel crosses of eight bread wheat cultivars were used to estimate the genetic parameters and types of genetic control for yield and yield components, and to determine the effects of environmental factors on these parameters. Parents and their F2 hybrids were grown in a randomized block design under irrigated and stressed (terminal drought) conditions. For all traits, except for number o...
In order to study the effect of foliar application of Fe, Zn and Mn on yield, yield components and protein content of two varieties of grain millet an experiment was conducted as factorial based on randomized complete block design with three replications in research field of Birjand branch, Islamic Azad University at 2010. In this study two millet varieties including Bastan (Setaria italica) a...
In order to identify the most important traits affecting yield in maize inbred lines and hybrids, an experiment was conducted in Shushtar City in 2009 and 2010 years. Fifteen inbred lines in 2009 and 28 hybrids in 2010 studied in two planting dates, 6 July (to coincide heat stress with pollination time and grain filling) and 27 July (normal condition) using a randomized complete block design wi...
grain discoloration caused by fungi agents, in crop season that the mature grain stage coincides with rain, it causes many damages. in this research effect of paddy discoloration of three varieties (hashemi, gohar and khazar) and disease index in two levels (high and low disease index levels) on grain apparent quality, milling properties and grain bending strength was investigated in a factoria...
The present study was undertaken with the objective to determine the nature and magnitude of variability, degree of association between yield and it`s component characters and their direct, indirect effects on grain yield in rice (Oryza sativa L.). Thirty three genotypes were evaluated for identifying their efficiency with respect to 20 yield and quality traits. High heritability with high gene...
in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...
In order to investigate the effect of water deficit tension on different growth stages on yield, yield components and produced grain quality of sorghum seeds cultivars, an experiments was performed as split plots based on randomized complete blocks design with four replications in Isfahan Ghiam Cultivation and Cattle Farm Company in 2017. The main factor including irrigation cut at four levels...
The aim of this study was to estimate the genetic divergence between African cowpea lines from the Cowpea Germplasm Bank of Embrapa Meio-Norte, Brazil. The morphoagronomic diversity of 57 cowpea lines was assessed using multivariate analysis. The germplasm was evaluated in August 2009 using a randomized block design with three replications based on the following traits: number of pods per pedun...
Percentage survivorship, developmental time, adult body length, and sex ratio of Plodia interpunctella (Hübner) reared on field-produced grain from sixteen cultivars of maize, Zea mays L., including several transgenic Bacillus thuringiensis (Bt) Berliner hybrids and selected non-Bt isolines, were evaluated under laboratory conditions. Compared with isolines, development was delayed and survivor...
