Tuberose (Polianthes tuberosa L.) has been recognized as one of the most important flowers in the flower industry. The agro-climatic situation of north Bihar has a better future prospect for its commercial cultivation. The screening of suitable genotype has a key role for the successful cultivation as the floral and vegetative characters are greatly influenced by different climatic situations. To address the demand of growers, the present genotype evaluation experiment was carried out with seven tuberose genotypes to asses the vegetative as well as floral characters under north Bihar Agro-climatic conditions. The experiment was laid out in randomized block design (RBD) with three replications at the Hi-tech Horticultural Research Farm of Dr Rajendra Prasad central Agricultural University, Bihar, Pusa (Samastipur) Bihar during the crop periods of 2015-16 to 2017-18 in three consecutive years. The tuberose genotype, ‘Bidhan Rajani H-1’ has reflected its better floral and other relat

Tuberose, genotypes, single types, double types, loose flowers, cut flowers, spike, rachis, florets, bulb and bulblets.

The research findings on the basis three years experimentation and pooled data (2015-16, 2016-17 and 2017-18) reveal that the different genotypes of tuberose have the potential to influence the floral and bulb / bulblets characters of the plant. Among the seven single type genotypes evaluated, ‘Bidhan Rajani H-1’ followed by ‘Prajwal, ‘Arka Nirantra’ and ‘Bidhan Rajani H-2’ are suitable for cultivation due to their floral qualities as well as shelf life potential over others genotypes under the Agro-climatic situations of North Bihar. It is obvious from the study that both the genotypes have very good economic potential and it would provide maximum net return to the growers/farmers of the State. Further, the performance of varieties of any crop differs from one region to another region. Hence, selection of genotype is an important criterion for successful cultivation of any crop.
