Variability studies in walnut (Juglans regia L) genotypes for different horticultural traits

The present investigations were carried out at the experimental farm of Department of Fruit Science, Dr YS Parmar University of Horticulture and Forestry, Himachal Pradesh during 2015–2017 to study the variability in different walnut genotypes. Analysis of variance showed significant differences among all the genotypes for the plant growth, flowering, yield and nut characteristics. The genotype Wilson Wonder recorded highest yield and performed better for other important horticultural traits among other studied genotypes viz Hartley, Kainthal Selection, Kashmir Budded, Kinnaur Selection, Montignac, Pieral Lara, Shimla Selection, Sirmour Selection and Solan Selection. Kainthal Selection was found to be the earliest and Montignac was latest for flowering. Therefore Wilson Wonder and Kainthal Selection can be future candidate genotypes for commercialization under mid-hills of northwestern Himalayas.
