Abstract:

To obtain hybrid fruit of blueberry cultivars, improve the efficiency of blueberry seedling nursery, select Chippewa, Bluecrop, Darrow, Northland, Duke, and Powderblue 6 different blueberry cultivated varieties as parents, artificial hybridization pollination test was taken and the hybrid seed breeding was proceeded. The results indicated that: low temperature and dry were useful for the preservation of blueberry pollen; blueberries of different haploidisations existed the phenomenon that they were not androlepsised; after the hybrid fruit mature the size and weight had difference; the germination rate of the hybrid pollination seed was 4%, GA3 could remarkably improve the emergence rate and the author generalized the blueberry artificial hybridization and seedling cultivation.
