Araştırma 2014-2015 ve 2015-2016 yetişme sezonunda Kırşehir Ahi Evran Üniversitesi Ziraat Fakültesi deneme tarlalarında gerçekleştirilmiştir. Denemede 8 kışlık kolza çeşitleri (Atenzo, Champlain, Elvis, EsMercure, Excalibur, PR46W10, PR46W31, Recordie) kullanılmış ve araştırma tesadüf blokları deneme desenine göre 3 tekerürlü olarak kurulmuştur. Araştırmada bitki boyu, yan dal sayısı, kapsül sayısı, kapsülde tane sayısı, bin dane ağırlığı, tohum verimi, ham yağ oranı ve ham yağ verimi parametreleri incelenmiştir. Araştırmada incelenen özelikler bakımından çeşitler arasında farklılıklar gözlenmiş ve bu farklılıklarda istatistiksel anlamda önemli çıkmıştır. Araştırmada 2015-2016 tarım sezonunda sonbahar yağışlarında yetersizlik nedeniyle bitkilerin gelişimlerinin zayıf oluğu, bununla birlikte aynı yıl ilkbahar döneminde gündüz sıcaklık artışına rağmen, gece ani düşük sıcaklıklar çeşitleri önemli ölçüde etkilemiştir. Bu olumsuz etki nedeniyle tohum ve ham yağ verimi 2014-2015 tarım sezonuna göre yaklaşık %50 düzeyinde bir azalma göstermiştir. Sonbahar yağışlarının sadece çıkış için değil aynı zamanda kış öncesi güçlü bitki rozeti oluşturması içinde yeterli düzeyde olmalıdır. Bitki boyu, yan dal sayısı ve ham yağ oranı yönünden Recordie çeşidi, kapsül ve dane sayısı yönünden ise PR46W31 çeşidi diğer çeşitlere göre daha yüksek değerlere ulaşmıştır. En yüksek verim denmenin ilk yılında PR46W10 (2939.17 kg ha-1) ve PR46W31 (2843.23 kg ha-1) çeşitlerinden elde edilirken ikinci yılında ise en yüksek tohum verimi EsMercure (1795.37 kg ha-1) çeşidinden elde edilmiştir. Her iki yıl ayrı ayrı değerlendirildiğinde tohum ve ham yağ verimi yönünden EsMercure, Atenzo, PR46W10 ve Recordie çeşitleri benzer koşullar için önerilmektedir
The research was carried out in the 2014-2015 and 2015-2016 adulthood season at the Ziraat Faculty of the University of Kırşehir Ahi Evran. In the experiment, 8 winter colza varieties (Atenzo, Champlain, Elvis, EsMercure, Excalibur, PR46W10, PR46W31, Recordie) were used and the research was established 3 rounds according to the test pattern of random blocks. The study studied the length of the plant, the number of side branches, the number of capsules, the number of one in the capsule, the weight of a thousand dams, the production of seeds, the percentage of raw fat and the production of raw fat parameters. Differences between varieties were observed in terms of the characteristics studied in the study, and these differences were statistically important. The study found that the growth of plants was weak due to insufficiency in autumn rainfall in the 2015-2016 agricultural season, however, despite the day-to-day temperature increase in the spring period of the same year, sudden low temperatures in the night have significantly affected the varieties. Due to this adverse effect, the production of seeds and raw oils showed a decrease of approximately 50% compared to the 2014-2015 agricultural season. Autumn rains should be sufficient not only for the output but also in the creation of a strong plant roset before winter. In terms of plant length, side branch number and raw oil ratio, the Recordie variety, and the number of capsules and dames, the PR46W31 variety has reached higher values than other varieties. In the first year of the highest efficiency, PR46W10 (2939.17 kg ha -1) and PR46W31 (2843. It is obtained from 23 kg ha-1 varieties, while in the second year the highest seed productivity was obtained from EsMercure (1795.37 kg ha-1 varieties). In terms of seed and raw oil production, EsMercure, Atenzo, PR46W10 and Recordie varieties are recommended for similar conditions.
The research was conducted at experimental field of Kırşehir Ahi Evran University Faculty of Agriculture fields in 2014-2015 and 2015-2016 growing season. Field experiment was designed based on randomized complete block design with three replications and 8 winter rapeseed cultivars (Aten Zo, Champlain, Elvis, Es Mercure, Excalibur, PR46W10, PR46W31, Recordie) were used. Plant height, the number of branches and capsules, seed number per capsule, thousand seed weight, crude oil ratio, seed and oil yield were evaluated in the study. The results revealed that the effect of cultivars was significant on plant height, number of branches and capsules, seed number per capsule, thousand seed weight, crude oil ratio, seed and oil yield. In the study also observed significant differences between years and these differences were associated with the inadequate development of rapeseed plant before winter due to insufficient autumn rainfall in the 2015-2016 agricultural season and increased winter cold damage. Due to this negative effect, the seed and crude oil yield decreased by approximately 50% compared to the 2014-2015 agricultural season result. Recordie cultivar in terms of plant height, side branch number and crude oil ratio, and PR46W31 cultivar in terms of number of capsules and grains reached higher values than other varieties. The highest seed yield was obtained from PR46W10 (2939.17 kg ha-1) and PR46W31 (2843.23 kg ha-1) cultivars in the first year and from EsMercure (1795.37 kg ha-1) cultivar in the second year of research. Considering the regional conditions, EsMercure, Atenzo, PR46W10 and Recordie varieties are recommended in terms of seed and crude oil yield.
