Abstract

In this research, two different minituber sizes (11.0-15.0 g and 2.0-4.0 g) of Concorde, Granola, Marabel, Marfona and Velox potato cultivars were used materials. The aim of the research was to determine relationships between yield and yield components and minituber field performance of different minituber sizes. The heavy (11.0-15.0 g) minitubers gave a higher stem number per plant, tuber number and tuber weight per plant than light minitubers (2.0-4.0 g). The light minitubers produced approximately 1-4 stems per plant and 5-7 tubers per plant. Whereas, heavy minitubers produced more stem and tuber per plant than plants from light minitubers. Usable tuber percentage as a seed (tubers bigger than 30 mm in size) were found approximately 80-85% in each two minituber sizes. In general, positive relationships were found between tuber weight per plant and plant height, stem number per plant, tuber number per plant and average tuber weight. These results of this study indicate that small minitubers can be used effectively to expand production of basic potato seed stocks.

Farklı Mini Yumru Büyüklüklerinde Patates (Solanum tuberosum L.) Çeşitlerinde Verim ve Verim Komponentleri Arasındaki İlişkiler

Abstract

Araştırmada, Concorde, Granola, Marabel, Marfona ve Velox patates çeşitlerine ait iki farklı mini yumru büyüklüğü (11.0-15.0 g ve 2.0-4.0 g) materyal olarak kullanılmıştır. Araştırmanın amacı, farklı mini yumru büyüklüklerinde verim ve verim komponentleri arasındaki ilişkileri ve mini yumru tarla performansını belirlemek olmuştur. Ağır mini yumrular (11.0-15.0 g) hafif mini yumrulara (2.0-4.0 g) göre daha yüksek bitkide sap sayısı, bitki başına yumru sayısı ve yumru ağırlığı vermiştir. Hafif mini yumrular bitki başına yaklaşık olarak 5-7 yumru ve 1-4 sap üretmişlerdir. Buna karşın daha ağır olan mini yumrular hafif mini yumrulara göre bitki başına daha fazla yumru ve sap üretmişlerdir. Her iki mini yumru büyüklüğünde, tohumluk olarak kullanılabilecek yumru oranı (30 mm’den büyük yumru) yaklaşık % 80-85 olarak bulunmuştur. Genel olarak, bitki başına yumru ağırlığı ile bitki boyu, bitkide sap sayısı, bitki başına yumru sayısı ve ortalama yumru ağırlığı arasında pozitif ilişkiler bulunmuştur. Araştırmanın sonuçlarına göre mini yumrular temel patates tohumluk stoklarının üretiminde etkili bir şekilde kullanılabilir.
