Mısır (Zea mays L.) Populasyonlarında Yağ ve Doymuş Asitlerin Genetik Kontrolü

Bu çalışma 2011 ve 2012 yılları içinde Çanakkale/Türkiye’ de yürütülmüştür. Bu araştımada 6 kendilenmiş hat ve yarım diallel melezlemeden elde edilen F1 bitkileri rol oynamaktadır. Amaç mısır tohumlarının içindeki yağın ve doymuş yağ asitlerinin kalıtımını belirlemektir. Bu doğrultuda yağ içeriği, palmitik asit içeriği ve stearik asit içeriği eklemeli ve dominans gen varyansları etkili bir şekilde belirlenmiştir. Mısır tanesi yağ içeriği için DAKD ve GAKD aralığı 0.211 ve 0.443 bulunmuştur. Wr- Vr grafiği ebeveynler hakkındaki yağ içeriği ve palmitik asit içeriği kalıtımı için tam dominatlık mevcut olduğunu gösterirken stearik asit içeriği kalıtımı için kısmi dominatlığın mevcut olduğunu göstermektedir.

Genetic Control of Oil and Saturated Fatty Acids in Maize (Zea mays L.) Populations

This study has been conducted in Çanakkale / Turkey during the years of 2011-2012. This research features sixinbred lines and F1 plants with half-diallel mating design. The aim is to determine the heredity of maize seed oil content andthe content of maize seed saturated fatty acids. Accordingly, the additive and dominance gene variances have been determinedfor the heredity of oil content, palmitic acid content and stearic acid content effectively. The range of NSHD andBSHD for maize grain oil content is determined to be between 0.211 and 0.443. The Wr- Vr graphs about parents shows whilethere exists full dominance for inheritance of oil content and palmitic acid content, there exists partial dominance for inheritanceof stearic acid content.
