to study general and specific combining ability of some rice varieties for grain physical properties and milling quality, a diallel design with five parents (hashemi, vandana, kadous, shahpasand and ir36) was used. parents and their f1 progenies (25 genotypes) were grown in a randomized complete blocks design with three replications in the research field of rice research institute of iran (rrii...

applying an appropriate statistical analysis is complementary for conducting a robust experimental design in plant and animal breeding. in these experiments 33 iranian bread wheat genotypes, cultivated in a randomized complete blocks design with three replications in two normal and saline conditions were evaluated at the field of national salinity research center located in yazd province, iran....

to assess heritability, gene action and combining ability of rice varieties for characteristics related to grain appearance and cooking quality, the progenies derived from direct and reverse crosses of the 6×6 complete diallel together with their parents included hashemi, hassani, shahpasand, kadous, vandana and ir36 were grown in a randomized complete block design with three replications in th...

introduction: weeds causing 15 % or more damage to crops, annually. the amount of these damages depends upon different factors such as cultivar type and weeds species. wild mustard is a cosmopolitan and most serious broad leaf weed in wheat fields which has widespread through world including iran. rapid emergence of wild mustard under cold condition and fast growth early in the spring are reaso...
