بررسی توسعه تنوع ژنتیکی از طریق دور گگیری و بررسی نتاج نسل ‭f1 ‬ژنوتیپ های گندم نان در شرایط دیم گرمسیری

Making crosses among different genotypes of bread wheat possessed valuable genetic characteristics to compound desirable genes and create genetic diversity is a fundamental work and a usual manner in traditional wheat breeding. So, In order to create new lines of bread wheat possessed good agronomic traits such as strong early vigor, earliness, good plant type, resistance to shattering, biotic and abiotic stresses 35 crosses were made at 2007-08 growing season in Gachsaran Agricultural Research Station among 30 parents. Furthermore for evaluation of F1 populations the seeds of each F1 cross were planted neighboring its parents at the next year. During the growing period some characteristics like plant height, peduncle length, tiller number, flag leaf length and spike length were controlled in parents and progenies. At the result 22 F1 populations were selected for further evaluation in the next year.
