بررسی مقدماتی ژنوتیپ ها و ارقام گلرنگ در شرایط دیم

To evaluate lines and varieties of safflower under rainfed conditions, a lattice experiment 8 ا 8 with two replocations was conducted in Agricultural Research Station, Golestan (fall planting).. Analysis of variance showed that safflower genotypes were significantly differ for seed yield. The highest seed yield belonged to line No. 64 with 4113 kg per hectare and the lowest seed yield belonged to line No. 22 with 2187 kg per hectare. All safflower genotypes werenot significantly different of Sina varity (check) except lines No. 22, 29, 36 and 43. The highest days to maturity belonged to lines No. 13 and 34 (188 days) and the lowest to lines No. 51 and 23(175 days). Correlation coefficients of seed yield with number of seeds per head was positive and significant.
