The present investigation entitled diversity for growth habit in the natural population of pecan nut (Carya illinoensis K.) in the Jammu province was carried out in order to document the available genetic variability in pecan nut germplasm and to select elite pecan nut genotypes possessing superior attributes and quality traits. During the survey, data was recorded on sixty (sixty) pecan nut trees growing in different areas of Rajouri and Poonch districts of Jammu province. Remarkable variability was observed in seedling pecan nut trees for different morphological, nut and kernel characters. Similarly, variations were also reported for other characters viz., tree vigour, growth habit, density of branching and one year old. Studies on tree vigour revealed substantial variability among the seedling raised pecan nut genotypes. In this study it was found that 47 genotypes (78.33%) were strong and 13 (21.67%) were medium in vigour. 17 (28.33%) genotypes were observed to have upright growth habit, 28 (46.67%) have semi-upright and 15 (25.00%) were spreading growth habit. 6 (10.00%) genotypes possessed sparsely dense canopy, 15 genotypes (25.00%) exhibited medium and 39 genotypes (65.00%) had highly dense canopy. Among sixty genotypes 17 (28.33%) were observed to have greenish brown colour of one year old shoot colour, 25 (41.67%) were having medium brown and 18 (30.00%) having brown colour of one year old shoot colour.
