The current study was conducted at Agronomy Section, ARI, Tandojam during the growing season of 2019-20 in order to assess new oat genotypes for their growth performance under the environmental conditions of Tandojam. For this study, a total of eleven new oat genotypes along with one check genotypes were grown for their evaluation. A total of seven characters were investigated, such as, crop stand (m-2), plant height (cm), leaves plant-1, number of tillers plant-1, leaf area (cm-2), green fodder and dry mater yield (t ha-1). The mean squares of all the genotypes were significantly differences (P≤0.05) with respect to all investigated characters including crop stand, plant height, leaves plant-1, tillers plant-1, leaf area, green fodder and dry matter yield, showing that these oat genotypes possess valuable genetic combinations for further improvements. Under the agro-climatic conditions of Tandojam, the maximum crop stand (96.66 m-2), greater green fodder (86.00 t ha-1) and also maximum dry matter yield (43.00 t ha-1) was produced by Entry-D; the Entry-H produced the tallest plants (96.66 cm) and maximum number of leaves plant-1 (68.00). Whereas Entry-F produced maximum number of tillers plant-1 (17.66). Hence, these oat genotypes may be preferred for commercial cultivation in the tested climatic conditions. Regarding correlation results, the traits crop stand (r=0.93**), tillers plant-1 (r=0.39*) and leaf area (r=0.38*) showed significant and positive associations with green fodder yield, hence these characters may be given priority in high yielding oat cultivar development.
