Variability studies for tree characters in F_1 hybrids of peach

摘要

The tree characters such as trunk girth, height, spread and volume are important in selection of superior hybrids as these characters have direct correlation with fruit yield of the tree. In the present studies, July Elberta, Alton, J. H. Hale, Knato-5, Saharanpuri and Quetta were used as female parent and wild peach as male parent. These crosses resulted in the production of hybrid seedlings which were quite variable in respect of the characters under study. The mean values for trunk girth of the cross varied from 23.50 to 32.50 cm, tree height 2.70 to 2.84 m, tree spread 1.80 to 2.13 m and tree volume from 5.59 to 7.54 cm3.
