to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...

improvement of one trait on its own will affect the performance of other traits because ofgenotypic correlations between traits. index selection is one of the tools used by plant breedersto overcome this problem. the purpose of this paper is to evaluate selection indices developedfor improving grain yield in rice (oryza sativa l.). forty-nine rice genotypes were cultivated attonekabon rice rese...

The present investigation was undertaken to evaluate ten germplasm of mung bean, used estimate genetic variability, heritability and advance for 16 characters. results showed significant differences among the bean genotypes in all All characters had a larger PCV, showing enfluence environmental variable on their expression. In study, PCV is higher than GCV under study. High coupled with high in...

Abstract In order to study the inheritance of grain yield and its components in bread wheat, two cultivars, Karchyya(drought and salinity tolerant) and Gaspard (sensitive to drought and salinity stress) were crossed.Parents together with F1, F2, F3, BC1and BC2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.Grain weight per...

pistacia atlantica is the most important tree species for the economy of many rural areas in west of iran, but no effort has been made for the genetic improvement of this species. the aim of this investigation was to study the genetic variation and inheritance of early growth traits in p. atlantica. for this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

in order to study the gene actions and heritability of the physical and chemical characteristics associated with appearance and cooking quality of rice grain, generation mean analysis was performed using a cross between two iranian rice cultivars, deylamani and sepidroud, having different quality characters. seeds of the parental lines and f1, f2, bc1 and bc2 generations were grown in randomize...
