Black pepper, the ‘King of Spices’ has high value in the international market. Natural varieties of Piper nigrum (black pepper) usually have non-branched spikes. However, a natural selection of black pepper viz. ‘Pepper Thekken’, shows inflorescence branching character i.e., about 20-30 branches per spike which is a trait of high economic value that is directly linked to the yield potential of this valuable spice crop. Auxin polar transport is reported to be one of the regulatory factors for branching architecture in many plants. Hence, in the present study, we tried to analyse the role of auxin in inducing branching trait in ‘Thekken’ through quantification of Indol acetic acid content in immature spikes using HPLC and comparing it with that of non-branching varieties like ‘Karimunda’ and “Panniyur-1”. The study revealed that the IAA content in the spikes of branching variety ‘Thekken’ was significantly low, that is about 1/4th and 1/3rd of ‘Panniyur’ and ‘Karimunda’ respectively.
