Abstract

This experiment was carried out at the Samiyan research station field affiliated to the Agricultural and Natural Resources Research Center of Ardebil province, located 10 km from Ardabil road to Meshkinshahr in 2016. The experiment were included eleven internal and external spring rapeseed genotypes as named RGS003, SARIGOL, ZAFAR, DALGON, JULUS, JACOMO, JERRY, JEROM, ZABOL10, HYOLA401 and HYOLA4815. The genotypes were carried out in a randomized complete block design with three replications. Phenological traits such as number of days to stem, anthesis and maturity; morphological traits such as plant height, number of primary and secondary sub branches, pod length and pod diameter, seed yield and yield components and seed oil content were investigated. Based on the results Dalgon and Zafar genotypes were late flowering and Hayola 4815, Zabol 10 and Hayola 401 were early flowering genotypes. Sarygal, Dalgon, Julus and Jacom genotypes were late maturity cultivars and RGS003, Zabol 10, Hayola 401 and Hayola 4815 genotypes were early maturity cultivars. The Julius and Hyola 4815 genotypes had the highest number of primary stems and the highest number of secondary stems was belonged to the Hyola 401 and Zabul 10 varieties. The highest plant height was obtained from the Julus genotype and the least amount of this value was from the hyola 4815 genotype. Hayola 4815 genotype with Zabul10 cultivar had the highest number of pods per plant and 1000 seed weight, and Sarigel genotype produced the lowest number of pods per plant and Dalgon cultivar had the least 1000-grain weight. The genotype Hayola 4815 plus Hayola 401 produced the highest number of seeds per pod and the least amount of this trait was obtained from Dalgon variety. Hayola 4815 genotype had the highest pod length and diameter in the genotypes studied in this experiment. The highest grain yield per unit area was obtained from Hayola 4815 genotype (1977.4 kg / ha), followed by genotypes Zabol 10 and Hayola 401 with significant difference. The minimum of this trait was obtained without any significant statistical difference from Sarigol, Zafar, Dallgon, Jules and Jacomo genotypes. The highest percentage of seed oil (38.9%) was obtained from Cherry cultivar, followed by Hayola 4815 genotype with significant statistical difference. Sarygol genotype was caused the lowest amount of seed oil (27.7%).
