Crossability in pomegranate (Punica granatum L.)

摘要

Hybridization was done among seven pomegranate varieties namely Ganesh, Daru, Kabul Yellow Nana Ruby Double flower and Amilidana and hybrids from August 2001 to February 2002 to evaluate the fruit set in different cross combinations and the effect ofseason on fruit set. Maximum fruit set was observed in crosses involving Ganesh, Ruby, Daru and very low in Kabul Yellow upon selling and same trend was observed in crosses involving Kabul Yellow, possibly due to poor cross and self-compatibility with other genotypes. The highest numbers of single crosses were done in Ganesh x Ruby followed by Daru x Ganesh and Ruby X Ganesh. Cross involving (Ganesh x Nana) resulted in higher fruit set when compared to other F_1's in the three-way crosses. Though maximum numbers of crosses were made in three way crosses but highest percentage fruit set was observed in selfing. In winter months, maximum number of fruits were produced in all crosses due to the low temperature and high humidity conditions thereby resulting in higher percentage of viable pollens.
