the chilling requirement of northern highbush blueberries ( Goldy and Lyrene 1984 ; Moore, 1965 ; Sharpe, 1953 ; Sharpe and Darrow, 1959 ). Hybridization between tetraploid northern highbush blueberry cultivars and diploid V. darrowii was first

have successfully produced several hybrids in Vaccinium ( Ballington, 1980 , 2001 ; Darrow and Camp, 1945 ; Lyrene, 2011 ; Rousi, 1963 ), but our previous attempts to cross diploid shashanbo with tetraploid highbush blueberry cultivars have not

-incompatible. The number of hybrid plants we obtained by pollinating 4301 flowers of tetraploid highbush blueberries with pollen from diploid V. elliottii (≈18 triploids and three tetraploids) was extremely low compared with the results of tetraploid × diploid

. This study had two goals: 1) to see if hybrids could be obtained by crossing tetraploid highbush blueberry cultivars with tetraploid V. arboreum produced using colchicine and 2) to see if the hybrids would be sterile or fertile. Materials and Methods

hybrids between highbush blueberry cultivars and tetraploid V. stamineum plants obtained by colchicine treatment of seeds and seedlings. The goal was to produce a broad-based hybrid population that could be used to combine horticulturally desirable
