dc.description.abstractABSTRACT The present investigation entitled “Evaluation and characterization of walnut on germplasm’’ was carried out at the Experimental Field of Department of Fruit Science (Oachghat Walnut block), Dr Y S Parmar University of Horticulture and Forestry Nauni, Solan (HP) during 2012-13 to 2013-2014. The trial was laid out in RBD with three replications. Twelve genotypes were taken for the study. The evaluation and characterization was carried out on number of tree, foliage, nut and kernel characteristics i.e. plant height, spread, girth, trunk cross sectional area, shoot length and colour. Leaf length, width, leaflet length, width, leaf area, leaflet area, shape of leaf and rachis length and colour. Time and duration of male and female flowers and catkin characters. Nut weight, length, width, thickness, index of roundness, pad features (thickness, width), shell thickness, shell texture and colour, kernel characters (weight, width, thickness and percentage). On the basis of growth characters Kainthal Selection was the most vigorous type. Seven genotypes were semi erect, four spreading and one erect. Leaf and leaflet shape was mostly elliptic to narrow elliptic. Leaf and rachis colour was yellow or brown and pubescence varied from slight to pubescent. Partap was early to flower and late in ‘Meylannaise’. Most of the cultivars/ selections were protandrous and female flowers were in cluster of three. Kainthal selection had highest nut weight (16.37 g) and least in ‘Hartley’ (7.98 g). Pieral-Lara nuts were most thick shelled and least in Hartley. Heavy kernel was in Kullu Selection (7.58 g) and least in ‘Hartley’ (4.39 g) whereas kernel percentage was maximum in Kullu Selection (49.00 %) and minimum in ‘Montignac’ (34.07 %). The nut yield varied from 3.50 to 87.50 kg/tree, highest being in Kainthal Selection (87.50 kg/tree).en_US
