Compatibility of Distant Hybridization between Different Sterile Lines of Rapeseed and Vegetable Varieties of Cruciferae

Compatibility of distant hybridization was studied by crossing 5 different rapeseed sterile lines with different vegetable varieties of Cruciferae.This is aimed at selecting rapeseed sterile lines and vegetable varieties with high hybridization compability.The results show that compatibilities of the crosses of the same sterile line with vegetable varieties of different types are remarkably different,and the compatibility of 714A is the highest.When different sterile lines are crossed with the same type of varieties,714A shows the highest hydridization compatibility,while 681A the lowest.The compatibilities of most hybridized combinations is low in the combinations crossed by different sterile lines and different hybridized combination F 1.The compatibility also is low in the combination crossed by 681A and vegetable varieties of Cruciferae with special traits.
