Abstract

Meiotic studies have been conducted on F 1 hybrids between Capsicum baccatum x C. cardenasii and C, baccatum x C. eximium. Meiotic studies with conventional squashes in Capsicum are sometime troublesome, since ehromosomes can be sticky so that it is dfficult to get a good separation of ehrotnosomes, It was therefore decided to study synaptonemal complexes at pachytene, as well as conventional squashes at diakinesis or metaphase. In this article, problems observed during these kind of studies were noted and possible explanations were given.

Capsicum boccatum x eximium ve C. baccatum cardenasii F1 Hibritleri Üzerinde Polen Boyanabilirliliği ve Mayoz Calışmaları

Abstract

Capsicum baccatum x C. eximium ve C. baccatum x C. cardenasii arasında yapılan melezlemeler sonucu elde edilen Fİ hibridler üzerinde mayoz ve polen boyaması çalışmaları yapılmıştır. Kromozomların birbirine yapışık durmasından ve bu yüzden iyi aynştınlamanıasından dolayı klasik ezme yöntemleriyle yapılan mayoz çalışmaları Capsicum'da iyi sonuç vermez. Bu yüzden diakinez veya metafaz aşamalarında yapılan klasik mayoz çalışmalarının yanısıra pakiten aşamasında synaptonemal kompleks çalışmalarının yapılmasına karar verilmiştir. Bu makalede yapılan çalışmalar süresince gözlenen problemler belirtilmiş ve bu problemlerin nedenleri açıklanmaya çalışılmıştır.
