Abstract

The study was held to evaluate relationships between seed yield (SDY) and its affecting components in common vetch (Vicia sativa L.) genotypes. It was analyzed the direct and indirect effects of the components on SDY using simple correlation and path coefficient analyses over the three consecutive growing seasons data. Field trials were performed in the research areas of the GAP International Agricultural Research and Training Center (GAP IARTC) in Diyarbakir, Turkey, during the 2008–09, 2009–10, and 2010–11 growing seasons with winter sowings. The experimental design was a randomized block design with three replications. Results from simple correlation analysis showed that pod numbers per plant (PNP) was significantly (P < 0.05) and positively correlated with SDY. The remaining yield component traits were highly significantly (P < 0.01) positively correlated with seed yield. In addition, path coefficients analysis showed that only biological yield (BLY) (3.7455 and 55.76%) and straw yield (SWY) (-3.0385 and 45.34%) had the strongest direct effects on seed yield. However, days to physiological seed maturity (DSM), pod numbers per plant (PNP), seed numbers per pod (SNP), harvest index (HTI) thousand seed weight (TSW) did not have any direct effects on seed yield. These five traits indirectly affected SDY, especially via BLY and SWY. Based on these results, we concluded that BLY should be used as the primary selection criterion for improving seed yield in common vetch

Path Coefficient and Correlation Analysis Between Seed Yield and Yield Components

Abstract

Bu çalışma, adi fiğ (Vicia sativa L.) genotiplerinde tohum verimi ve tohum verimine etki eden özellikler arasındaki ilişkilerin değerlendirmesi amacıyla ele alınmıştır. Araştırmada tohum verimi ve verim kompenentleri arasındaki ilişkiler, basit korelasyon analizi ile belirlenirken, incelenen özelliklerin tohum verimi üzerindeki doğrudan ve dolaylı etkileri ise path analizi ile belirlenmiştir. Araştırma, Diyarbakır GAP Uluslararası Tarımsal Araştırma ve Eğitim Merkezi Müdürlüğü deneme alanlarında 2008-09, 2009-10 ve 2010-11 ekim sezonlarında kışlık olarak tesadüf blokları deneme desenine göre üç tekrarlamalı olarak yürütülen tarla denemelerinden elde edilen gözlem verilerine dayanmaktadır. Yapılan korelasyon analiz sonucuna göre, bitkide bakla sayısı (PNP) özelliği ile tohum verimi (SDY) arasında 0.05 düzeyinde olumlu ilişki saptanırken, incelenen diğer tüm özellikler ile tohum verimi arasında 0.01 düzeyinde önemli ve olumlu ilişki saptanmıştır. Path analiz sonucuna göre ise, tohum verimim üzerinde en yüksek doğrudan etkisi bulunan özellikler biyolojik verim (BLY) (3.7455 ve 55.76%) ve saman verimi (SWY) (-3.0385 ve 45.34%) özellikleri olurken, fizyolojik olum gün sayısı (DSM), bitkide bakla sayısı (PNP), baklada tane sayısı (SNP), hasat indeksi (HTI) ve bin tane ağırlığı (TSW) özelliklerinin tohum verimi (SDY) üzerinde herhangi bir doğrudan etkileri saptanmamıştır. Bu beş özelliğin tohum verimi üzerinde etkileri dolaylı ve özellikle biyolojik verim ve saman verimi özellikleri üzerinden olmuştur. Araştırma bulgularına göre; adi fiğde tohum verimini artımak amacıyla yapılacak ıslah çalışmalarında biyolojik verim özelliği başlıca seleksiyon kriteri olarak kabul edilmelidir
