abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...

genotype×environment interactions (geis) can affect breeding programs because they often complicate the evaluation and selection of superior genotypes. this drawback can be reduced by gaining insights into gei processes and genotype adaptation. the objectives of this research were to evaluate: (1) the yield stability of promising wheat lines across locations and (2) the relationship among the t...

The significance of haploid plants as genetic and plant breeding tools has been recognized for a long time. Haploid production techniques including anther culture, isolated microspore culture and intergeneric hybridization between wheat × Hordeum bulbosum and wheat × maize have been used to produce homozygous lines which accelerate breeding programs. In this study, wheat × maize hybridization a...

The diallel mating design is an important tool used by plant breeding programs to obtain information on trait inheritance. Knowledge of gene action, heritability and genetic advance from selection is a prerequisite for starting a breeding program for developing varieties of maize. Five maize S7 lines and their F2 progenies were studied in a 5 × 5 half-diallel crossing design to evaluate the gen...

to investigate the genetic diversity of 21 rapeseeds (brassica napus l.), 20 semi-random isj and ssr primers were used. primers produced a total number of 158 (81.5%) polymorphic bands (51 ssr and 107 isj bands). average numbers of polymorphic bands for isj, ssr and combined of them were 10.7, 5.1 and 7.9, respectively. pic values ranged from 0.0150 for specific primer o110d08 to 0.3420 for sem...

  Estimation of genetic variation is very important in breeding programs and existing of high genetic variation lead to increase the response to selection. The objective of this study was to investigate genetic variation for agronomic traits and yield components in 20 entries of sesame including 15 breeding lines and 5 local populations. The genotypes were evaluated in a randomized complete blo...

some cerasus sub-genus wild species that are used as rootstocks in sour and sweet cherry propagation can also be employed in breeding programs. the aim of this study was to clearly evaluate some characteristics of subgenus cerasus genotypes to be used in the future cherries' breeding programs. in order to evaluate some morphological characteristics of the vegetative parts as well as seeds ...

Bread’s quality depends on wheat flours quality and quantity and for the goal to be achieved, the usage of suitable wheat varieties should be considered. Present study focuses on analyzing doubled-haploid lines of wheat’s bread backing quality and the relationship between qualitative traits and glutenins reservoir proteins. In current work, traits related to bread backing quality of 30 doubled-...
