بررسی ارزیابی مقدماتی ارقام و لاین های گلرنگ به منظور انتخاب ژنوتیپ های مناسب در شرایط دیم معتدل سرد

Selection from 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 dry-land regions of Iran. Present study carried out with 100 safflower genotypes selected from last year trail in fall planting in 1010ا lattice squar experiment with 2 replications at Sararood research station. Each genotype was planted in 3 rows with 4 m length, 30 cm row spacing and 10 cm plant distance. In addition to normal agronomic operations like weed and pest control some agronomic characters has been recorded. Results showed that there were significant differences between genotypes for five characters including plant hiegth, no. of heads per plant, no. of branches per plant, seed yield and oil yield. The range of seed yield of genotypes was vast so that genotype number 64 had the highest (1350 Kg/ha) and genotype number 380 had the lowest (264.5 Kg/ha)seed yield. Finally, 16 genotypes with seed yield higher than one tone per hectar and 17 other high seed yield genotypes selected until next year along with three varieties (Sina, Zarghan279 and 411) totally 36 genotypes evaluate.
