Abstract

The BDB-L genotype, a hybrid chestnut derived from efforts to introduce the ‘Bouche de Bétizac’ cultivar to Türkiye. In this study, it was characterized morphologically and phenologically to evaluate its potential for nut production, pollination, and chestnut honey production. The study was conducted from 2020 to 2023 in Samsun, Türkiye. Examined key traits in this study are tree vigor, leaf morphology, catkin characteristics, bur structure, and nut quality. The genotype exhibited vigorous growth with a semi-upright habit, intermediate shoot thickness, and distinctive leaf traits, including attenuate tips, dot-shaped teeth, and a large leaf area. The male and mixed catkins displayed a spreading habit and longistaminate filaments, reflecting high pollination efficiency. The burs were large, squarely globular, and contained an average of 2.87 nuts, while the nuts were transverse ellipsoid in shape, with very bright pericarps, light cream kernels, and a thin, easy-to-peel seed coat. Notable nut characteristics included low seed penetration, low pericarp splitting (1.2%), and the absence of polyembryony, ensuring uniform kernel development. These traits align with market preferences for fresh consumption and processing, including confectionery applications. The phenological timeline revealed early bud burst and mid-season ripening, indicating adaptability to temperate climates. The findings suggest that the BDB-L genotype is a high-quality, versatile chestnut cultivar with significant potential for commercial nut production, pollination enhancement, and chestnut honey production.

Özet

BDB-L, Türkiye’ye ‘Bouche de Bétizac’ çeşidini kazandırma çabaları sonucunda elde edilen bir hibrit kestane genotipidir. Bu çalışmada, BDB-L genotipinin morfolojik ve fenolojik özellikleri incelenerek, meyve üretimi, tozlayıcı karakteri ve kestane balı üretimi için potansiyeli değerlendirilmiştir. 2020-2023 yılları arasında Samsun, Türkiye’de gerçekleştirilen çalışmada; ağaç kuvveti, yaprak morfolojisi, çiçek yapıları, kapsül yapısı ve meyve kalitesi gibi temel özellikler incelenmiştir. Genotip, yarı dik bir büyüme karakterine sahiptir. Güçlü bir büyüme karakterine sahip olan genotip, orta kalınlıkta sürgünler, sivri uçlu yapraklar ile nokta şekilli dişler ve geniş bir yaprak yüzeyi gibi ayırt edici yaprak özelliklerine sahiptir. Erkek ve karışık çiçek püskülleri, yoğun bir yapıya sahip olup, uzun erkek organ filamentleri ile yüksek tozlaşma verimliliği göstermiştir. Kapsüller, büyük, karemsi küresel şekilli olup kapsül içerisinde ortalama 2.87 adet meyve bulunmaktadır. Meyveler ise enine elipsoid şeklinde olup, çok parlak kabuklara, açık krem renkli iç kısımlara ve ince, kolay soyulabilen bir tohum kabuğuna sahiptir. Düşük tohum penetrasyonu ve kabuk çatlama oranı (%1.2) ile poliembrioninin az oranda görülmesi gibi dikkat çekici özellikler, homojen bir iç gelişim sağlamıştır. Bu özellikler, taze tüketim ve şekerleme gibi uygulamalar için pazar tarafından tercih edilmektedir. Fenolojik zaman çizelgesi, erken tomurcuk patlaması ile orta mevsim olgunlaşmasını ortaya koymuş, bu da ılıman iklimlere adaptasyonunu göstermiştir. Bulgular, BDB-L genotipinin ticari kestane üretimi, tozlayıcı çeşit olarak kullanımı ve kestane balı üretimi için önemli potansiyele sahip, yüksek kaliteli ve çok yönlü bir kestane genotipi olduğunu göstermektedir.
