بررسی تنوع ژنتیکی ارقام و لاینهای گلرنگ به منظور انتخاب ژنوتیپ های مناسب در شرایط دیم

Genetic variation is the most important factor to successful selection and breeding programs. So, evaluation of germplasm collections is one of the most important methods to recognise siutable genotypes and can help breeders to release new varieties. Safflower is an ancient and local crop that is well adapted to diffrernt dryland regions of Iran. Present study carried out with 90 safflower genotypes selected from last year trail which have been planted in fall at three research stations viz. Sararood, Maragheh and Shirvan. Each genotype was planted in 2 rows with 3 m length and 30 cm row spacing. In addition to normal agronomic operations like weed and pest control some agronomic characters has been recorded. Results showed that there were wide variation for all agronomic characters except days to maturity at all three research stations.finnaly, according to yield and some other agronomic characters 18 superior genotyes along with three varieties (Sina, Zarghan279 and 411) totally 21 genotypes selected to evaluate in next year.
