Evaluation of Newly Developed BIDI Tobacco (Nicotiana tabacum L.) Genotypes for Seed Oil

Abstract

Tobacco (Nicotiana tabacum L.) seed oil (TSO), a byproduct of tobacco leaf production, has been shown to be a substitute for a diesel fuel in a raw or chemically modified form. The oil content of the seed ranges from 36% to 41% of seed dry weight. In the present study the experiment was conducted with 8 genotypes ABD 132 (Nandyal Pogaku 2), ABD119, NyBD56, NBD290, NBD289, ABD146, A119(C) and Nandyal pogaku-1(C) in randomized block design from 2018-19 to 2020-21at Regional Agricultural Research Station, Nandyal with an objective to evaluate the newly developed genotypes for seed yield and yield attributes and to find out oil yield and quality of tobacco seed oil. Results showed that the entries ABD132 (2199 kg/ha), NBD290 (2150kg/ha), ABD145 (2137 kg/ha) and NBD289 (2067kg/ha) has recorded significantly higher cured leaf yield and chemical quality parameters were recorded in its leaves of the genotypes under untopped condition, the lowest chloride content of 0.78 % in NBD 290, higher nicotine content (2.82%) in ABD132 (Nandyal Pogaku 2) and higher reducing sugars (1.55%) in A119, making it suitable for bidi smoking. Entries ABD 132 (745 kg/ha) & A119 (738 kg/ha) recorded higher seed yield and oil yield potential (234 kg/ha) and (235 kg/ha) respectively. ABD 132 has recorded maximum nicotine yield potential (62.01 kg/ha). These genotypes (ABD 132 and A119) used further breeding programmes to increase the oil yield and to use the by-products.
