Tatlı Rezenenin Foeniculum vulgare Mill. var. Dulce Uçucu Yağ Oranı ve Tohum Veriminin Geliştirilmesine Yönelik Bazı Fenotipik Seleksiyon Kriterleri

Abstract

Bu araştırmada, tatlı rezenin Foeniculum vulgare Mill. var dulce tohum verim ve bazı verim öğeleri arasındaki ilişkileri belirlemek amaçlanmıştır. Yirmi adet rezene hattı materyal olarak kullanılmıştır. En yüksek pozitif ilişki r=0.915 biyolojik verim ile tek bitki verimi arasında belirlenmiştir. Bitki boyu, dal sayısı, şemsiye sayısı ve şemsiyecik sayısının tek bitki verimi üzerine etkisi pozitif olmuştur. Bin tohum ağırlığı, uçucu yağ oranı ile negatif yönde ilişkili bulunmuştur. Tohum verimine maksimum - negatif etkiyi biyolojik verim yaparken, en yüksek pozitif ve direk etkiyi şemsiyecik sayısı göstermiştir. Ayrıca, tek bitki verimi, bitki boyu ve bin tohum ağırlığı tohum verimini olumlu şekilde etkilemiştir. Uçucu yağ oranı üzerine tek bitki veriminin direk etkisi %32.95 en yüksek olmuş, bunu bitki boyu %24.60 ve dal sayısı %15.11 takip etmiştir. Sonuç olarak, tek bitki verimi, şemsiyecik sayısı ve bitki boyu tatlı rezenenin uçucu yağ oranı ve tohum veriminin iyileştirmesine yönelik fenotipik seleksiyon kriterleri olarak önerilebilir

Some Phenotypic Selection Criteria to Improve Seed Yield and Essential Oil Percentage of Sweet Fennel Foeniculum vulgare Mill. var. Dulce

Abstract

The research was aimed to determine relationships between seed yield and some yield components of 20 sweet fennel Foeniculum vulgare Mill. var dulce lines. The highest positive correlation r=0.915 was recorded between biological yield and single plant yield. Plant height, number of branches, number of umbels and umbellets had a positive effect on single plant yield. One thousand seed weight was negatively correlated with essential oil percentage. The highest positive and direct effect on seed yield was shown by number of umbellets, while maximum negative and direct contribution to it was made by biological yield. In addition, single plant yield, plant height and one thousand seed weight affected seed yield positively. Single plant yield had maximum direct effect 32.95% on essential oil percentage followed by plant height 24.60% and number of branches 15.11% . In conclusion, it could be suggested thatsingle plant yield, number of umbellets and plant height are good phenotypic selection criteria to improve seed yield and essential oil percentage of sweet fennel
