Abstract

Bu çalışmanın ana amacı bazı beyaz ve mor çiçekli Capsicum türleri arasında melezlemeler yaparak ve polen tüpü gelişimini inceleyerek bu iki grup Capsicum türleri arasında melezlenebilme olanaklarını ortaya koymaktır. Araştırma sonuçlarına göre; C. tovarii hariç geriye kalan mor çiçekli türler melezlemede dişi form olarak kullanıldıkları zaman beyaz çiçekli türlerin polenleri inhibe edilip ve hiçbir tohum elde edilemezken, resiprokal melezlemelerde beyaz çiçekli türlerin pistilleri mor çiçekli türlerin, C. tovarii dahil, polenlerini inhibe etmemiş ve melezlemelerin çoğunluğundan tohum elde edilmiştir.

A Study on Crossability Relationships Between Some of The White- and Purple-Flowered Capsicum Species

Abstract

The main objective of this study is to reveal the crossability relations between some of the white-and purple-flowered Capsicum species by making pollination and studying pollen tube growth of crosses conducted between the white-and purple flowered species. Results showed that while there was a strong inhibition of pollen tubes, when a purple-flowered species, excluding C. tovarii, was the female and no F1 hybrid was obtained. On the other hand, in reciprocal crosses pistils of the white-flowered species showed no inhibition of pollen tubes of purple-flowered species, including C. tovarii, and in most of the crosses seeds were obtained.
