Description ABSTRACT
The present investigations entitled “Studies on hybridization in pomegranate (Punica
granatum L.)” was conducted at pomegranate blocks, Department of Fruit Science, Dr. YS Parmar
University of Horticulture and Forestry, Nauni, Solan house during. Six soft seeded cultivars namely
Ganesh, G-137, Dholka, Nabha, Jodhpur Red, Mridula and three hard seeded cultivars namely
Kandhari Hansi, China Seedling and Bush Large were used for pollen and hybridization studies.
Pollen viability assessed by Acetocarmine solution (2%), Tetrazolium solution (1%) and Erythrosine
B (0.1%). The pollen viability in Acetocarmine ranged from 90.79 to 97.86 per cent whereas in
Tetrazolium and Erythrosine B, pollen viability varied from 88.94 to 97.13 per cent and 80.76 to
94.65 per cent respectively. Maximum pollen germination was obtained in 10 per cent sucrose
solution after 72 hours with 52.32 per cent germination and minimum was recorded in 20 per cent
sucrose solution, having no germination after 24, 48 and 72 hours in some varieties. Amongst all the
cross combinations attempted the highest (80.95%) fruit set was observed in Dholka x Kandhari Hansi
and minimum fruit set was recorded in Dholka x Bush Large (37.60 %). Fruit retention ranged from
8.14 to 29.60 per cent in all the cross combinations. Seed germination from hybrid seeds ranged from
75.12 to 95.35 per cent in all cross combinations. The total of 21,968 seedlings of different cross
combinations has been raised under polyhouse conditions. From present investigations it may be
concluded that there is, thus, absolute need to continue further work in respect of raising and
evaluation of the resultant hybrid progeny to select promising individuals yielding fruits with soft
seeds and blood red aril colour.
