The present study on the performance evaluation of different garlic genotypes under Nilgiris which is a temperate zone was taken up to assess the phenotypical and yield parameters during the year 2018 in Kharif season. The field trial was carried out in the research farm of Horticultural Research Station, Tamil Nadu Agricultural University, Ooty, The Nilgiris. The work was taken up with eight garlic genotypes under randomized block design with three replications. The identification of newer types of garlic genotypes for morphological and yield parameters combined with disease and pest resistance will help in increasing the productivity of the crop. The productivity is a major factor which helps in increasing the yield potential of garlic in India for which continuous evaluation will help to identify more better yielding types. Among the genotypes evaluated for its performance, the entry GN-18-52 recorded the maximum plant height (71.11 cm), average bulb weight (44.16 g), average clove weight (24.40 g), marketable yield and total yield was observed in entry GN-18-52 (97.80 q/ha) and (102.20 q /ha) leaf length (49.50 cm) was maximum in GN-18-57. Considering the better performing characters for positive attributes which will support for its yield and quality, the genotype GN-18-52 considered to be promising and selected for further trials with a view to consider for release of a variety.

The results of the present study to evaluate the performance of the different garlic genotypes under the Nilgiris conditions during Kharif season indicates that entry with GN-18-52 performs better for most for most of the morphological and yield attributing characters which can be further assessed under large scale trials to impart its adaptability under the similar temperate growing regions for better yield and productivity.
