Adaptation of Winter Type Germany Originated Rapeseed Brassica napus ssp. oleifera L. Cultivars Under Ankara Conditions

Abstract

The aim of this research was to determine the adaptation ability of winter type German originated rapeseed cultivars under Ankara conditions. This study was carried out to determine the yield and yield components of eight rapeseed cultivars Ceres, Cobra, Diadem, NPZ 71, NPZ 74, NPZ 82, NPZ 66, NPZ 62 under Ankara conditions in 1993-1994. In both years, the sowing was done as early as possible to enable plants to enter winter conditions in rosette stage. Plant height, numbers of axillary branches, numbers of pods on the main stern; pod length, number of seeds per pod was observed in the field as yield components. Seed yields, thousand seed weights and oil ratio were also determined after harvesting. According to the results of the average of two years, the highest seed yield 322.01 kg/da was obtained from cv. NPZ 62 and the highest oil ratio 37.12 % was determined in cv. NPZ 66. Yields and oil ratio of these rapeseed cultivars were found to be high even though agricultural applications such as irrigation, hoeing and fertilization were not applied. The results indicated that these cultivars could be grown easily under Ankara conditions.
