Abstract: Seedling selections based on non-metric characters after catogerization of 90 walnut seedlings evaluated at two districts, Solan and Sirmour (H.P), revealed substantial variation for selection of better types to add to the prevailing walnut diversity. The entire seedling population at the studied sties, Jauna Ji and Dharo ki Dhar (Solan) and Wasni (Sirmour) were characterized in three different girth classes (C-I, C-II, C-III). For brevity the districts were represented as So (Solan) and Si (Sirmour). The non-metric traits recorded are highlighted, plant growth was usually either erect or semi- erect with varying number and percentage, both dominated spreading growth habit. Leaf and leaflet shape was mostly elliptic or broad elliptic in most genotypes at both the sides. Among the entire population narrow leaf apex dominated oblong shape. Leaf colour was predominately green least was dark green. Shoot pubescence was slightly glabrous/ glabrous few were pubescent, most frequent shoot colour was green brown in most seedlings at both sides. Among the nut features broad elliptical and ovate outscored other shapes studied. Nut base was rounded in nature least observed was cuneate type. Trait pistil point prominence was categorized, position of pad on suture varied usually was evident on upper half of the nut. Shell surface was moderately smooth, least possessed rough surface, adherence of two halves and shell strength were intermediate type. Commercially important features- kernel colour was mostly amber very few had extra light colour. After tasting kernel flavor was rated as satisfactory. Plumpness was moderate was most seedlings with no shrivelage, kernel removal was moderate. These characters were highly significant to select desirable types.
