بررسی ارقام و لاینهای گندم متحمل به شوری در شرایط زارعین استان قم

This experiment was conducted base on the results of pereviouse year trial & under saline condition in & cropping season, with three new promising wheat lines numbers, & and &&and in comparison with Roshan and kavir as controls, in a saline soil with EC && ds & , EC= &&ds & and replicates in each , within && plots for selecting and determining more toletant varities and lines to salinity Some important characters such as flowering date, hight of plant & Kernel weight number of grain per spike, lenght of spike and yield of grain and were inventoried during the experiment. The results of this experiment showed that the line number and & with grain yield of &&& and && Kg & obtaind maximum respectively, also the line number & and Roshan veriety had maximum & kernel weight & and signiticant difference with another treatments and obtained maximum amounts in length spike & & & & and &&respectively), line number & in number of grain per spike &&, Roshan veriety in height && cm, the line number & and Roshan veriety in dry matter ( && and &kg& respectively), and lines number , & &&and kavir in harvesting index, with &,&&&and &&& respectively).
