Agronomic and chemical properties of hybrid oriental tobacco (Nicotiana tabacum) lines and their stabilities
2020
KINAY, Ahmet
The present study was conducted at six Basma tobacco production centres, viz. Esencay, Endikpinar, Uzumlu, Karayaka, Evciler and Yenice in 2016 and 2017. The aim was to find the best stable hybrid Basma tobacco lines with attributes desired by the growers and buyer firms. Four hybrid lines and their parents were used as the plant material of the study. Plant height, leaf width, leaf length, yield, grade index characteristics were investigated and nicotine, glucose, fructose, chlorogenic acid and rutin analyses were performed with an HPLC system. Genotype stabilities were determined with regard to yield and grade index. Attribute means, regression coefficient (b), regression constant (a), coefficient of determination (r2), coefficient of variation (CV%) and standard deviation of regression (S2d) were used as the stability parameters. As the average of six locations, plant height was 109.22 cm, number of leaves was 28.34, leaf width was 12.09 cm, leaf length was 22.71 cm, yield was 1612.2 kg/ha, grade index was 64.10%, nicotine content was 1.69%, glucose content was 4.54%, fructose content was 5.07%, chlorogenic acid content was 388.32 ppm and rutin content was 607.05 ppm. Hybrids had greater leaf width, leaf length, yield and chemical attributes than the parents. Significant differences were observed in all of the investigated parameters. H2 (dry leaf yield: 1808.6 kg/ha, grade index 66.20%) hybrid was identified as the most stable and promising registration candidate hybrid.
