Abstract

The inheritance of grain yield per plant, flag leaf width, and flag leaf length was studied applying Jinks-Hayman diallel analysis in an 8 x 8 wheat cross population involving the bread wheat (T. aestivum L.) genotypes Cumhuriyet, Kaşifbey, Ziyabey, Marmara, Basribey, Malabadi, Yüreğir, and Seri-82. The crosses were made by hand, without reciprocals, in field conditions from March to May 2001, and the field experiment was conducted during the October 2002 to June 2003 growing season. The analysis of data showed that the additive variance component (D) was significant for flag leaf width (P < 0.01). The dominance variance component (H1) was significant for flag leaf width and grain yield per plant. The dominance level variance component (h2) and corrected dominance variance component (H2) were significant for all 3 traits studied (P < 0.01). The Wr/Vr graphs indicated overdominance for grain yield per plant and flag leaf width, while partial dominance was inferred for flag leaf length. Flag leaf length was significantly and positively correlated with flag leaf width (r = 0.803). Yüreğir x Malabadi crosses should be considered for maximizing photosynthetic area of the leaf.

Özet

Jinks-Hayman tipi analiz metodu uygulanmas›yla 8 x 8 diallel ekmeklik bu¤day melez populasyonunda bitki bafl›na dane verimi, bayrak yaprak uzunlu¤u ve geniflli¤inin kal›t›m› araflt›r›lm›flt›r. Araflt›rmada Ege Bölgesinde yayg›n olarak yetifltirilen sekiz ekmeklik bu¤day çeflidi olarak Cumhuriyet, Kaflifbey, Ziyabey, Marmara, Basribey, Malabadi, Yüre¤ir ve Seri-82 kullan›lm›flt›r. Denemedeki melezleme ifllemleri 2001 Mart-May›s aylar›nda; tarla denemeleri ise Ekim 2002 - Temmuz 2003 tarihleri aras›nda yap›lm›flt›r. Verilerin analiz edilmesi neticesinde bayrak yaprak geniflli¤i için eklemeli varyans komponenti (D), bayrak yaprak geniflli¤i ve bitki bafl›na tane verimi bak›m›ndan dominantl›k varyans komponentinin (H1) önemli oldu¤u tespit edildi. Dominantl›k düzeyi (h2) ve düzeltilmifl dominantl›k de¤erleri (H2) üzerinde çal›fl›lan üç özellik içinde önemli bulunmufltur. (P < 0.01). Wr/Vr grafi¤i bak›m›ndan incelendi¤inde bitki bafl›na dane verimi ve bayrak yaprak geniflli¤i karakterleri afl›r› dominantl›k de¤erleri gösterirken bayrak yaprak boyu karakteri k›smi dominantl›k özelli¤i göstermifllerdir.Bayrak yaprak uzunlu¤u bayrak yaprak geniflli¤i ile pozitif ve önemli korelatif iliflkiye sahip sahip oldu¤u bulunmufltur (r = 0.803). Yüre¤ir ve Malabadi genotiplerinin melez kombinasyonunun maksimumbayrak yaprak alan› için en uygun kombinasyon oldu¤u tespit edilmifltir.
