Melezleme ile Elde Edilen Elma Genotiplerinde Meyve Kalitesinin Değerlendirilmesi

Bu çalışma ile Eğirdir Meyvecilik Araştırma İstasyonu’nda yürütülen elma çeşit ıslah programına ait melez popülasyonunda bulunan genotiplerin meyve kalite özellikleri incelenmiştir. Çalışmada görünüm ve yeme kalitesi gibi daha çok tüketici özellikleri göz önünde tutulmuş ve meyve kalitesi uzman panelistler tarafından duyusal analizlerle belirlenmiştir. Faktör analizindeki temel bileşen grupları esas alınarak yapılan çoklu karşılaştırma testinde 5 genotipin (‘91’, ‘109’, ‘177’, ‘63’, ‘120’) (‘Kaşel 37’ x ‘Delbarestivale’) hem referans olarak alınan ‘Amasya’ elmasından, hem de ebeveynlerinden daha üstün olduğu tespit edilmiştir. Bununla birlikte ‘368’ nolu tip (‘Kaşel 41’ x ‘Williams’ Pride’) nispeten daha düşük puanlar almasına karşın o dönem olgunlaşan çeşitlere kıyasla yeme kalitesinin yüksek olması ve erkencilik özelliğinden dolayı bölgesel olarak değerlendirilebilirliği sebebiyle seçilen tipler arasında yer almıştır. Böylece seleksiyonun ilk aşaması tamamlanmış ve 70 genotip içerisinden 6 genotipin (‘91’, ‘109’, ‘177’, ‘63’, ‘120’ ve ‘368’) hem görünüm, hem de diğer yeme kalite kriterleri bakımından diğerlerine kıyasla daha üstün olduğu belirlenmiştir.

Fruit Quality Assessment in Apple Genotypes Obtained by Crossing

In this study, fruit quality attributes were evaluated in hybrid populations of apple breeding program conducted at Eğirdir Fruit Research Station. Consumer properties such as appearance and eating quality were considered, and fruit quality was determined by sensory analysis by expert panelists. The five genotypes (‘91’, ‘109’, ‘177’, ‘63’, ‘120’) (‘Kaşel 37’ x ‘Delbarestivale’) were superior than both parents and ‘Amasya’ apples taken as a reference in multiple comparison test performed based on principal component groups in factor analysis. However, The type ‘368’ (‘Kaşel 41’ X ‘Williams' Pride’) took place among selected type due to it can be evaluated regionally because of early maturation, and the eating quality is much higher than maturing varieties in that period despite the fact that relatively lower scores. The first stage of selection of genotypes was completed with the essay, and 6 types (‘91’, ‘109’, ‘177’, ‘63’, ‘120’ and ‘368’) among 70 genotypes have been found to be much superior in terms of both appearance and others eating quality criteria.
