ارزیابی عملکرد ژنوتیپ های بهاره گلرنک در مزارع زارعین در شرایط دیم

Due to importance of safflower and its role as an oilseed crop in dry lands and in order to study its situation in dry land farming of province, this study carried out with 5 safflower promising genotypes with one check (Isfahan local) in 3 locations of Khorasan province viz. Faruj, Bojnord and Kashmar under dry land conditions. Each genotype was planted in 8 rows with 6 m length and 30 cm row spacing. Experimental design was RCBD with 3 replications. Analysis of variances showed that there is a significant difference between genotypes in terms of thousand kernel weights and stand. However, there was not any significant difference between grain yields of treatments. Mean comparison of experimental genotypes showed that in Bojnord, genotype with temporary number 333 had the highest grain yield (582 Kg/h) and in Kashmar (Koohsorkh region) genotypes PI-250596 and Cyprus local had the highest grain yield which would be released for cold dry lands after demonstration and seed multiplication.
