a breeding hexaploid salt tolerant wheat line (ms-81-14) was produced from crossing of an iranian salt tolerant wheat line (1-66-22) with inia cultivar (from cimmyt) at karaj research station in 1991-92 cropping season. the f1 plants were grown at karaj in 1992-93 cropping season, furthermore f2-f6 populations were evaluated under salinity stress conditions (ecsoil&water; = 8-12 ds/m) in isfaha...

pishgam was selected from the progeny of a cross between barakat iranian bread wheat cultivar and chinese 90-zhong 87 winter-habit ( bkt/90-zhong 87) in 1995. the f1 generation seeds were planted in karaj station in 1995-96 cropping season. selected-bulk method was applied to segregating generations from f2 to f5 generations for characters such as winter hardiness, plant height, straw strength,...

the main objective for development and introduction of the new cultivar was to a achieve a high yielding and adaptative to short growing period or a catch crop, suitable for growing in different areas of iran. after preliminary selections carried out during 1998-2000, 72 foxtail millet populations which had been collected from different parts of iran, were examined and based on different agrono...

ABSTRACT-Several herbicides are registered for selective weed control in sugar beet; however, no single chemical herbicide can control all weeds in beet fields. Frequently, two or more herbicides may have to be combined sequentially or as tank mixed to achieve adequate broad-spectrum weed control. In order to evaluate the effects of some combinations of broadleaf herbicides on sugar beet yield ...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...
