tailieunhanh - Relationships between yield and yield components on currently improved spring rapeseed cultivars

This research was conducted in Erzurum in 1991 and 1992 seasons using 14 spring oilseed rape (Brassica napus ssp. oleifera L.) cultivars in order to investigate the relationships between yield and yield components by correlation and path analyses. | Tr.

Positive values were obtained in both seasons between seed yield and the characters: days to flowering, plant height, number of branch, number of pods per plant, number of seeds per pod, pod diameter, pod length, 1000-seed weight, and oil content. However, seed yield was significantly and positive correlated with only number of pod per plant and 1000-seed weight in both seasons. Relationship between oil content and protein content was negative. Path analysis identified 1000-seed weight as having the greatest effect on seed yield, with number of pods per plant having a large secondary effect. Islah Edilmiş Yeni Yazlık Kolza Çeşitlerinde Verim ve Verim Ögeleri Arasındaki İlişkiler Özet: Bu araştırma, 1991 ve 1992 yıllarında Erzurum’da 14 yazlık kolza çeşiti kullanılarak verim ve verim unsurları arasındaki ilişkilerin korrelasyon ve path analizleri ile incelenmesi amacıyla yürütülmüştür. Her iki araştırma yılında da tohum verimiyle, çiçek açma süresi, bitki boyu, dal sayısı, bitkideki kapsül sayısı, kapsüldeki tohum sayısı, kapsül çapı, kapsül uzunluğu, 1000-tohum ağırlığı ve yağ içeriği arasında pozitif ilişkiler belirlenmiştir. Ancak, tohum verimi, sadece bitkideki kapsül sayısı ve 1000-tohum ağırlığı ile her ik yılda da pozitif ve önemli ilişki göstermiştir. Yağ içeriği ve protein içeriği arasında ise negatif bir ilişki .
