The effects of selfing on the pollen fitness and the seed set in peper (Capsicum annuum L.)

Bu çalışma Şanlıurfa yerel biber populasyonunda, Sİ'den S7'ye ve sonsuz kendilenmiş (Soo) kabul edilen double-haploid (DH) hatlarda, kendilemenin polen performansı ve tohum oluşumuna etkilerini incelemeyi amaçlamıştır. Deneme 1995-2001 yılları arasında Harran Üniversitesi Ziraat Fakültesi deneme alanında dört tekerrürlü tesadüf blokları deneme deseninde yürütülmüştür. Deneme sonucunda kendileme serilenlerinde polen performansı, çiçek basma polen miktarı, polen canlılığı, meyve başına tohum miktarı ve 1000 tohum ağırlığı bakımından kendileme depresyonu olmadığı belirlenmiştir. Çalışılan biber populasyonunun başlangıçta yüksek oranda kendilenmiş olduğu, üreticiler tarafından yüksek miktarda tohum içeren meyvelerin seçimine dayalı seleksiyon yapıldığı kanısına varılmıştır. Bu nedenle çalışılan özellikler üzerine herhangi bir olumsuz etkiyle sonuçlanmamıştır.

Kendilemenin biberde (Capsicum Annuum) polen performansı ve tohum oluşumuna etkileri

This study aimed to investigate the effects of selfing on the pollen fitness and seed seting in Sanliurfa local pepper population, in various inbreeding generations through the Si to S7 and double haploid (DH) lines, derived from same population consider selfing infinite time (Soo). Field trials were carried out in the experimental field of Faculty of Agriculture in Harran University through the 1995-2001 cropping seasons, employing randomized complete block design with four replicates. The results indicate that, there was no inbreeding depression among various selfing series for number of pollen flower"1, pollen viability, total seed" weight fruit'1 and 1000 seeds weight. It was concluded that studied pepper population was highly inbreed initially depending on selection practices by farmers, retaining fruits with high seed contents. So selfing did not resulted in any deleterious effects on the characters under study.
