Abstract: The investigation on Bio-morphological characters of garlic plant in relation to thrips populationwas carried out at Horticulture farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur during 2020-2021. From the foregoing investigation it becomes clear that among the 20 genotypes the maximum plant height was recorded in the genotypes Yamuna safed-4 (38.43cm) and minimum plant height was recorded in genotype GN-20-08 (28.32) and the correlation of thrips with plant height (r =-0.52*), highest neck diameter was observed in the genotype GN-20-50 (6.65cm) whereas, the lowest neck diameter was observed in GN-20-52 (4.68cm) and the correlation of thrips with neck diameter (r =-0.47*),  the maximum angle between leaves was observed in the genotype GN-20-41 (17.53º). and the minimum angle observed in GN-20-52 (8.1º) and the correlation of thrips with leaf angle found (0.70**) and the maximum number of leaf/plant recorded in the genotype GN-20-43 (6.63) and the minimum number of leaf/plant observed in GN-20-62 (4.92) and the correlation of thrips with plant height (r =-0.48*). Bio morphological character i.e., plant height, neck diameter, leaf angle and number of leaf /plant found significant but negatively correlated.

Keywords: Bio-morphological, garlic, leaf angle, neck diameter, plant height, thrips
