- Abstract:
- The reciprocal crosses were carried on between two red-flowered strawberry cultivar ‘Pink Beauty’ and ‘Pretty Beauty’ and a white-flowered cultivars ‘Honeoye’.The flower and fruit characteristics of offspring were investigated in order to obtain new ornamental and eatable strawberry species，and provide fundamental basis for red-flowered strawberry cross breeding.The results showed that fruit-setting rates of the two hybrid combinations，‘Honeoye × Pink Beauty’ and ‘Honeoye×Pretty Beauty’ were 73.21% and 70.21% respectively，while were 20.13% and 32.96% respectively in their reciprocal crosses.The proportion of red-flowered seedlings and white-flowered seedlings in the offspring was 1∶2.3.The flower color appeared white，light pink，pink，deep pink and red in the offspring，some petals basally deep and white spots phenomenon.In the offspring of ‘Honeoye×Pink Beauty’，the range of the maximum fruit weight was from 10.4 g to 27.4 g，no super parent strain.In the offspring of ‘Pink Beauty× Honeoye’，the range of the average single fruit weight was 15.2 g，the maximum fruit weight was 59.4 g，wihich could be used in fruit cultivation as intermediate materials.In the offspring of reciprocal crosses of ‘Honeoye’ and ‘Pink Beauty’ had no super high-parent phenomenon in average single fruit weight，yield per individual，hardness and so on；but two individuals with high vitamin C content of 116.2 mg·(100g)-1 and 104.9 mg·(100g)-1 respectively was obtained，the characteristics was significantly better than that of both parents.
